The reason for "bonding" non current carrying metallic components to "ground" is to equalize the electrical potential to ground in the event of a short circuit inside the equipment. If you come in contact with those now energized components, you could die. This could save your life. As someone who has nearly died from an electrocution due to a missing bond to the ground, I am fanatic for proper grounding and bonding. I do agree with you relating to rebar for a ground rod. I would refer you to your local electrical code to determine if rebar and what diameter is accepted in your locality. Lightning will destroy almost anything. There is no grounding system that is truly effective against a direct lightning strike. Directing lightning away from your solar panels, as you described, is a valid point. BTW: the metal on my panels/wind turbines and neutral conductors have been bonded to ground rods for over 20 years. There are no failures yet due to lightning, even though there has been lightning in the area multiple times. I just opened the box, so I'll probably get hit next week! 16:57

@JOHNDANIEL1 11 месяцев назад

People who find voltage coming from their solar panel frames are the folks who worry me 😂. They need to ask why one isolated piece of aluminum (solar panel frames) makes its own power, but another one of identical build (aluminum window frame) don't. And funny thing is when I removed all the ground wires it disappeared. People who put a array up far from their homes ground rod and don't connect the solar ground to their home also seem to have no transient voltage from their panel frames. Hmmm.

@heatclift4532 2 месяца назад

Your right, grounding is not part of a DC circuit. But I think you missed a point: earth ground on DC circuits serves a slightly different purpose. It's for your SAFETY. It provides the shortest path for DC current to flow in case of an unbalanced leak (positive/negative only leak, where there is little to no ISC until touched by something that completes the circuit). Without the earth ground, if the circuit has a leak, the current will flow through anything touching the ground, INCLUDING YOU. So yeah, in low voltage it's almost useless, but on an array of 10+ 600W PV panels where the circuit has 400V+, it's a life saver....

@JOHNDANIEL1 2 месяца назад

I think I've said here and everywhere that exceeding 60vdc should have a fault system. That includes neon alert bulbs from frame to independent ground to active grounding but not residential shared.

@Blackbird-zo1su 11 дней назад

Exceeding 60vdc meaning input from the panels? I have circuit breakers on my solar system in my rv. My system is not grounded. My rv is not grounded. I know I’ve asked this question before, but now I’m unsure of what I should do. Can you help?

@JOHNDANIEL1 11 дней назад

@@Blackbird-zo1su If your choosing to go as high as 60 volts DC, you need real safety by using at least inline fuses or breakers. I prefer staying under 44 volt, ( pair of 100 watt panels in series is 44 open voltage ) and likely to be felt but not likely to injure. Over that it gains deadly levels fast. You do not need to ground the panel frames, no one has to. But creating a short safety is wise no matter what your voltage is. Best breakers to use are Mathus, you need a box amzn.to/4fgc0Zd And sized breakers that are just higher then your panel amps amzn.to/3SiWDVN Example - 300 watts solar would be 25 amps in a 12 volt system. Always buy a few extra breakers, and always get a box with at least 1 or 2 more spaces than your solar already uses so you can expand or option other sources.

@FishFish1995 6 месяцев назад

Thank you for the precious info. I have an important question if you could help me with it. I have an off-grid inverter that has a voltage of 60V between Neutral and Ground of the inverter AC output. I am new in solar systems... I hear that this voltage should be 0V in order for RCD breakers to work properly. After some research, some say that a way to solve this issue is to bridge ground and neutral on the electrical panel and ground them both. Now I can see you say that inverters don't need to be grounded, but if there is a voltage between neutral and ground and you need protection from an RCD breaker, a way must be found... I'm actually looking for a solution... What's your opinion regarding neutral/ground bridging on the inverter AC output? Thankful for any kind of reply 👍

If you are looking for a truly awesome lightning repelling/diverting system, look up Nikola Tesla's lightning rod/repeller. It looks almost like an umbrella, but is designed to perform very similar to how you describe setting up the solar panels on metal roofing. Really interesting stuff. Another thing that most people fail to grasp is that when lightning strikes the ground, the ground itself becomes energized and having something grounded to the spot that is energized can cause something that is sometimes known as "ground source lightning" and can also cause those grounded objects to become energized and be much MUCH more dangerous than an ungrounded metal object. The main reason I am so involved with grounding/ground isolating stuff is my expensive radio equipment requires a good ground for proper signal propagation, but improper grounding can cause ground loops and lightning and even electric discharge damage by those same electromagnetic waves being transmitted and received. I learned a long time ago that there is a LOT of bad information out there regarding grounding. Another thing people don't realize is that electricity does not just take the path of less resistance, it is actually really complex. See Ohm's law to truly understand how electrical energy will take all paths to ground and divide equally along those paths according to the resistance and then faraday's laws to see how adding inductance and capacitance can have a major impact on it. The simple subject of grounding is so insanely complex that most electricians and electrical engineers don't fully understand it, there is just so much nuance that goes into it.

@JOHNDANIEL1 Год назад

I base my study and results on 2 things, Sir Benny Franklin and Faraday's laws. Faraday using a all copper roof on a cabin next to a all wood shingle roof was trying to prove how copper was dangerous, He was a pissy man. He learned the opposite. He learned that electrochemistry was not that simple, the lightning on the project in north France on the coast, right in the marsh, a storm hot spot, it struck the carbon loaded chimney of the wooden house 3 times. Never touched the copper house or its chimney right next to it. Conclusion by Vander Hoff the resident, the copper make the house protected. Private notes to his parish. In reality it made the load of the ground sourcing much more spread out. In reality, lightning DID strike both. But the concentration of energy diffusing outward was spread out on the all copper, leaving no real damage. But the energy was so focused on the wood framed houses chimney it blew the top off it and the cast iron frame from Ingles ship wrights, which both homes had, down below warped. Little is known of his off Britain experiments done by fellows, but his findings on electrolysis caused by as he put it, the silent energy, showed how the later designs of the Faraday cage came about. Note to be accurate, I am prejudiced toward his Savant Qualities, I am kin to Sarah Barnard, she was married to Michael Faraday, her grand father is direct blood line from my Germanic/Lithuanian roots.

I'm about to install a 360w solar panel backup system into my cabin which is on the grid. I bought a SunGoldPower 12v inverter/charger that will be fed from a regular household 15 amp circuit/outlet. The batteries are charged by the inverter/charger when the grid is up, but by the solar panels when the grid is down. The inverter/charger has a ground to the 200amp service panel through regular 14 awg house wiring. But it also has another grounding lug off its metal case. I was contemplating using that lug to ground my solar panels, but found your video as I do research on grounding. I think I'll do some more research, but this video has me re-thinking what I thought before.

@JOHNDANIEL1 8 месяцев назад

Just realize the design of the power grid, with the earth involved, power created by rotating mass is not in any way the same as the generation/conversion of power from DC current. The "HAIR ON FIRE" panic stricken fear mongers who demand you ground connect all your DC circuits would fire you in 1 second if you drove a ground rod through the floor of their pick up to "ground it" since it has a AC alternator and DC circuits. Solar for safety is fused. All DC should be fused. But be very careful back flowing your inverter through some residential wiring since it can be bonded common with neutral (ground direct) and may fry your inverters or introduce stray voltage in your existing ground circuits.

@avlisk 8 месяцев назад

Thank you for the quick reply. I do know that the main panel they just installed is bonded common to neutral at the outside box. The power is then distributed inside to a 200amp service panel which (of course) is not bonded ground to neutral. It's one of those circuits that feeds my living room outlet where the SunGoldPower inverter/charger will be plugged in. Keep up the good work, it's appreciated by us still "in school". @@JOHNDANIEL1

A “detachable" 12” tall copper lightning rod (Strike termination device) attached to the center of the roof ridge should offer protection from lighting strikes. Although a lighting rod does not invite lightening strikes, if one does occur, the lightning will be directed to the path of least resistance from the rooftop copper clad lightening rod to the ground (Internationally known as Earthing). A lightening rod directs the lightning flow through a continuous, low-impedance, ground electrical conductor (GEC) #6 - #4 rated American Wire Gauge (AWG), stranded copper conductor protected in green nonconductive sheathing, bonded to a ground rod embedded in the earth. It is preferable to have a continuous GEC; however, if a splice is necessary, only irreversible compression type connectors listed as ground and bonding equipment should be used. The lighting rod(s) is tethered (bonded), by the grounding conductor, to a copper clad 8’ ground rod(s) which safely dissipates the electrical energy in to the ground. Since electricity always tries to return to its source, the ground rod is not intended for ground faults (Between two hot wires or a hot and a neutral) but to dissipate static electricity buildup or external electrical surges from lightning strikes to its source, the ground.

@briankober4879 6 месяцев назад

I think you make a good argument regarding attracting lightning to a different ground source other than through your modules and houses grounding system. I.e. erecting a large lightning rod or grounding your houses via an existing perimeter fence as these would make for a safer path to discharge a lighting bolt around a houses property. With that said, for many homes in the U.S. these methods of handling lightning surges just are not available. Some houses do not have an existing fence they can turn into a lightning attractor/arrestor and building a large lightning rod taller than the house is just not feasible as there often isn’t any yard space. Although at times it seems the NEC is pedaling new codes to sell additional electrical components and installation, I do not think at its core that it is its purpose. ESPECIALLY with regard to grounding codes the purpose is to continue to make residential electrical circuits safer. In fact, building a large lighting rod or creating a grounding fence as you have suggested would In the end be more expensive to the homeowner(for most houses) than bonding solar modules together as part of a homes lighting protection. You are correct in saying a circuit does not need a ground to operate, the modules will produce power without a ground. However, the grounding conductor is installed for use in worst case scenarios such as a lightning surge BUT ALSO for shorts within a circuit or static electricity build up. These problems are all best solved via a ground. To divert unwanted current quickly rather than exist as unwanted voltage running across the module’s frames. You mention that vehicles and tractors are not grounded to earth. Of course they are not, having a constant connection to earth in all motor vehicles across the country is not feasible. However if it was I bet it would be required. Now consider trucks that move hazardous materials, static buildup within the truck due to normal operation can ignite flammable materials and this has been known for many years. Sometimes these trucks DO have a connection to earth via a chain dragged along the ground to dissipate the voltage differential. Perhaps for off grid systems or systems in dispersed residential settings a better grounding system should be in place than using the house ands its infrastructure(solar modules) to handle lightning surges. But in most cases, congested neighborhoods would be better off with each house able to handle a surge independently. The modules on the roof could be damaged by lightning and if no path to earth is created the surge could burn up the wiring of the solar system causing a fire. The goal is NOT to attract lightning(even if this is an unwanted byproduct). Lightning is an unpredictable energy source and it is best for a house to just be as prepared as it can be.

Set them in concrete in a triangle 3 points at 4 feet apart 18" deep in concrete. You taper them to a peak, using bolts or plating connect the tops as you place another one in the center with a added 10 foot 6" piece down low under the 4th one ( single piece home depot $15), to end up about 29 feet total tube height. Very stable. You place 1/2 rebar up the center of the 4th one, the middle tube till its 2 feet out the top of the center tube with additional 1/2 rebar welded or clamped with heavy cable clamps till your down to the bottom and into the ground of the center tube about 2+ foot deeper than its 12 to 18" concrete. I may do a drawing and place it on my web page www.mydcvolts.com that I have been forgetting to update for a few months LOL! This 30+ feet is generally much much taller than any solar, much taller by 10+" feet than a 2 story home, and more static attractive than any trees. You can go a little higher with a little common sense addition or adaptation. Mine cost about $130 to build, and is why I will not worry about my solar.

The thing is your dc wires will then be your shortest path to ground through your inverter and through you who is using some equipment. You should have surge protectors on both the + and - lines on your panels. You then ground your frame so that that is the shorter path to ground.

What about the sub-panel that is supplied by the inverter with 240v, the circuits will need a ground to meet code ? So do I connect a ground wire from the main panel? There is no other connection to the grid system, yet. Or would I connect to a ground rod (rebar) ?

@JOHNDANIEL1 3 месяца назад

When you go to AC voltage and anything over 60 volts DC then proper breakers and grounding is required on the AC side if its to join a existing system, the DC side can be left ungrounded as long as you have proper breakers but if your doing the most evil thing on the planet *GRID TIE* connecting then you must pay all the massive fees, follow every rule, connect to all ground connections and expect your pay off in a few hundred years. As for the panel frames, you can ground by choice unless forced to do so, using a ground rod on them separate from anything your house is using and over 25 feet from a existing ground. Myself, I choose NOT to attract lightning to my panels but instead a dedicated lightning post but if you can get good replacement insurance on the panels then it's not a horrible idea to attract lightning so you can get new ones ever so often from a insurance claim.

It won't protect from lightning damage, indeed will make the panels a "lightning rod", but will protect personnel from any potential buildup, either static or for feedback thru the cells from the inverter. Obviously, you can't ground panel frames on an RV, but doesn't mean a home installation isn't better if frames are grounded.

@JOHNDANIEL1 5 месяцев назад

Ground if you feel its for you. But just know that about 99% of those who say they have voltage in their panel frames got it from sharing a single homes ground rod with the common neutral/structural ground bonded 120/240 utility panels, inverters ground lug, solar controllers ground lug and solar panels. So if you do ground them, DO NOT connect that circuit to the home or inverters system, ground them separately at least 30 feet away from any existing ground rod. They do collect atmospheric static in rare conditions but so does you car pop you with a static jolt from time to time.

@tomasvanhoof9786 Год назад

AFAIK, there are 2 different reasons for grounding: (a) for functionality reasons (AC transformer, electrical wire fence, ...) and (b) for safety. With (a) you connect one of the wires to the ground which acts as an extra conductor, and with (b) you connect metal frame parts to an earthing rod or loop. With (b) in place, you prevent people from being shocked when touching the metal frame if a damaged DC or AC cable also touches that frame. Without grounding, the electricity goes from the defective cable via the frame through your body to the ground, which can be deadly. With the frame grounded, the pathway of least resistance is via the ground wire to the ground, so when you touch the frame then, almost no or very little current will go through your body. As well as the situation that the Ground Fault Current Interuptor can detect the dangerous situation and disconnect the electricity, indicating there is a dangerous situation that should be corrected. Or in case of solar panels, the inverter detects that there is an insulation fault that should be looked in to. PV systems are being grounded for protection of your loved ones, and other people. I'm no expert, only an apprentice, the experts can correct or agree with me.

@beebop9808 8 месяцев назад

You're right except that the DC circuit from your panels is an isolated circuit. There is no potential to earth ground unless you create it by bonding the return (-) to ground first. Shorting the positive wire to the frame will do nothing unless the positive and negative both are shorted. Then something is going to blow, hopefully fuses that you've installed on your panels instead of your panels. Equipment grounding is absolutely best practice where that potential exists and does include most all AC circuits and non-isolated DC circuits.

Thank you for the video. After watching your video I did not ground my system. I am having problems with my EG4 inverters. flickering lights, incinsitent power. Tech support asked if I grounded my panels. I told them no. they told me I needed to. I decided to use some leftover pv wire I had and ground my panels to satify that being the issue or not. While installing the grougning I could hear a electrich buzz every time i touched my pannels, I even got a light shock at one point. I pulled out my multimeter and had 140VAC and 1amp on the panel racking and frames. Turns out many all in one inverters do not isolate their PV inputt from AC output and it leaks into the pv lines and gets into the racking somehow? Once grounded the cuurent is no longer in the panles. just wonding your thoughts on this? would appriciate the input. also grounging the array did not solve any of the issues i was having with flickering and what not. thanks

@JOHNDANIEL1 5 месяцев назад

What do you suppose caused totally isolated aluminum frames to be electrified? It's like saying I installed a inverter and solar into my Dodge van, now my Chevy pick up parked near it shocks me every time I touch it. Literally, the same way of thinking! The voltage you get when touching a ground wire to a panel is from the existing ground wire "supplied common ( bonded circuits)" loop being made, It happens when your panels are mounted on metal racking on metal frames or metal roofs. This does not ever happen to any electrically floating un grounded panels mounted on wood! Wonder why right! Induced current is looking for a conductor when your playing with it, and find it in reverse by a ground that's connected to a homes existing system of wiring which has a bonded Common(neutral)/Ground design. Technically, your making a jumper, and it makes many things behave odd. People seem to think a inverters output is identical to a power plants system, it is not. It is a imperfect clone not designed to rely on earth ground for balance. It's not a identical product. Yet, using a All-In-One inverter charger is not the problem that will make 100% non-electrified aluminum become current carrying items, connecting it to something upstream is what does that. See how it all behaves when you DO NOT connect and share your inverter to the homes metal, ground, or bonded utility based and still connected to utility, system!

@@chasegj Yes, Just do a experiment. Remove the ground line on the inverter or run 2 wire for 120 volt, 3 wire for 240 volt and watch how the whole thing changes. Consider how you would wire the same system into a old school bus/RV, Grounding is to chassis, not to anything else. NO ground rod, no ground strap related to AC voltage on the panels, but some do a DC ground to chassis due to static from 70 mph air flowing over panels. And no one gets electrocuted, it is safe there, so its same for a home system. RV's do not bond ground and neutral and if they do they tell you to separate it if installing a inverter. The ground on them is often only metal BOX to chassis, not a shared Neutral bar to Chassis. I prove this all by disconnecting the ground, plugging into a inverter, and then measuring the volts from the ground wire to the ground post on the inverter and getting wild voltage on it anytime it is fed into a bonded power box. This feedback sometime affects your DC negative to your panels.

When a AC unit kicks on, a high inductive load happens, and your on utility plug in, the common can get high loaded, it's spike can feed to ground, the chassis, and POOF your inverter or controllers eat it!

This solar breaker box is not connected to the barn grid power subpanel. How do I ground the solar power breaker box? The inverter has a grounding lug, the PV combiner box has a grounding bar in it also. Are the three components mentioned (solar breaker box, PV combiner box, inverter) all grounded together and connected to an earth grounding electrode? I have decided not to ground the 180 watt panels due to the lightning issue. Thanks for your videos!

@JOHNDANIEL1 Год назад

Using a multi meter, with everything up and operating go and test from those ground lugs to the Positive & Negative on your DC system/Battery +/-. See if you get any circuit power, such as 10+ Volts DC in your results. If you do not, its only chassis grounding and you can using a 10 awg wire connect those items together and earth ground them for a simple static controlling ground. Static can gather in a chassis for a DC system ( touch the outside of your car body get a little ZAP when weather and atmospheric is right ) That only requires 3 feet of stripped copper coiled up in a 18" to 24" deep hole in the ground near your system. As for safety on your solar frames or any roof mounted metals, go at least 50 feet and place a basic lightning rod 10+ feet higher than your solar is and you will cover those needs too.

@JOHNDANIEL1 Год назад

When you connect a inverter, to a existing ground of a building or house then your sharing that ground. If a electrical condition exist that relies on that ground you can end up with a damaged inverter. They place this option on inverters to pass a improper UL and NEC rating. It is ok to do this with generators with a AVR in them, not ever to be done with brushless generators for the same reason. I only run on a GFCI from the inverter, then only use 2 wire on all shared circuits. Many inverters are different, but almost all will not run safe, especially high frequency models, sharing a ground with existing wiring. The best outcome is NOT to share house wiring, install new dedicated unless your buying a pricy quasi grid tie style inverter but using them means a huge cut in ability when grid fails.

@johnbrizendine7716 Год назад

@@JOHNDANIEL1 Exactly!!! The only reason a UPS can do that; even though it's not really the same as having an inverter tied directly to the main breaker box, is because it has a lot of power conditioning circuitry and is specifically designed to act as a filter/conditioner for the grounded power going into it and to also automatically switch to backup battery power if the main power going into it is lost or over voltage or under voltage. I don't actually use inverters in my solar setups, I use all industrial grade high power with high power factor rack mounted APC UPS units that I have custom programmed for working as both UPS and standalone inverter systems.

Is there a possibility you will get shocked as water passes down your body and rolls off the roof to the earth which is ground? I have a 12 volt off grid system and my panels are all under 50 volts dc and in series, so I am not worried about grounding them. But some guys have systems where the DC volts can be 200 volts plus since they wired their panels in parallel. Thanks, if you have the time to answer.

If your wired wrong and your using the isolated aluminum frames as a conductor your already on the wrong path. However, if your up on a roof when rain is obvious your also starting the day bad. As for the rain and shock hazard the roof being metal far exceeds your conductivity of pure water ( rain water has no magnesium or saline in it to conduct much power under 500 volts ). **The scenario is like saying: *If I jump out a plane without a parachute but the ground is all marshmallows, and the wind is blowing 900 mph how hard will I hit the apple tree that's not there!* In other words, random rarity that if you die, it's a world record worth bragging about in the afterlife!

@JOHNDANIEL1 Месяц назад

Yep, wrong about that. The Solar panel is a device that only makes DC voltage. A Solar Controller is a device that takes that "wattage" and converts it to DC Charging to place the results into a storage battery system. From that storage battery you get again, DC voltage until you send that to a Inverter, which is a device that synthetically makes a alternating current/voltage to use on AC devices. Since a Inverter is not a power generation system ( utility ) it is making the conversion from DC to AC power with some form of buck boosting and switches to create a sine wave, usually Mosfets and transformers. That process only creates 2 fields. Some are both synthesized as both hot + Line 1, hot - line 2 and some from pure sinusoidal wave of ZERO on Hertz. NONE are using a ground to create the output. The controller circuit in a inverter is used as the safety system, it actually can not fail either, so it is safer than a actual "earth Ground" since it does not require numerous connections to function. It works as follows. *Billy grabbed the output of a inverter, he was SHOCKED to see it immediately shut off. He heard from the brilliant code talkers that it would kill him. Then Billy learned a Inverter is sensitive to "wave variation" and will fault so fast that it's considered the safest power system to use in Ambulances and Hospital equipment since only 1.5% wave variation will fault it to stop working verses up to 15% in a Utility Grid non GFCI systems with double bonded circuits.* The Ground post on a inverter do not actually do anything but chassis grounding, however you do not have voltage in the chassis, TILL YOU GROUND IT!!!

Consider this basic reality. A solar panel is in no way different in electrical conductivity than a aluminum house window. Yes the cells in the glass make power however none is sent through the metal frames and no electrical characteristic exist until you do one unusual thing to the solar panel that you do not do to your aluminum house windows. The one thing that "enhances, conducts and creates" it's electrical property is when - YOU GROUND IT. Science, if you still believe in it Post Covid 19, says one thing. When you add a earth ground to anything that is not electrically phased then you introduce a non-natural attraction to lightning and a atmospheric eddy current into that item. To show you how that works. Get a 100 foot extension cord, using one wire in it ground well one end. Go to the other end and with a multimeter place the + probe into the ground and the neg probe onto the corresponding wire you grounded 100 feet away. Note the now existence of voltage. The earth is electric. And when you connect isolated aluminum panel frame to it, you end that neutral isolation and induce a pending static charge.

Connecting to a ground with a inverter will damage the inverters, it will stop or damage your induced short detection safety system in that inverter so may makers knowing "people do not understand the output is NOT utility" often make a burn trace on the board to vaporize when a bonded system is connected to. A industry secret but a must have ability.

It may be pointed out the following, for US-users: 1. Two-wire DC systems between 60-300 V are required to be grounded (i.e. to ground one current-carrying wire, usually the negative) [sec. 250.162(A) of the 2020 NEC]. 3. PV system grounding is not required but is allowed [sec. 690.41(A)(1) and 690.41(A)(4)]. In other words, it’s optional to ground the negative or positive wires of a PV array. 4. PV equipment grounding is required [sec. 690.43]. In other words, the electrician must ground the metal frames of the PV modules (solar panels). 5. The NEC really just requires to connect an EGC to the exposed metal parts of the PV system, not to install a new grounding electrode system. But installing a new grounding electrode system and connecting it to the PV equipment is allowed and optional. 6. In telecom systems, all 48-V systems have the positive wire grounded.

As explained in the video, this is for DC non commercial systems and home power use. Mine is 12 to 36 volt, many I have installed are 140 to 300 volt and require a arrestor and some structural grounding by code but not the panels frames. All must be fused, all are fused, but no DC circuit can share a ground with a AC system. We installed NiCad in many Telecom systems, mostly Sprint, some T-mobile. No grounding on the 56 volt modules was ever done, just the battery case and shunts had a circuit breaker to ground. All the solar used on those were 90 volt and frameless with no ground on them but the cables were in metal conduit that was grounded.

0:23: The US uses a TN-C-S grounding arrangement for the low-voltage (secondary) distribution system. The neutral wire between the secondary winding of the transformer and each house’s service disconnect is considered a PEN conductor, it combines the neutral and ground wires into one. After the service disconnect, it splits into a separate neutral wire and ground wire. However, I disagree with the statement said @ 0:25 that the transformer ground wire is part of the circuit. It’s not. It does carry current, since the neutral wire is multi-point grounded by grounding it once at the transformer and also at each house once. But it’s not supposed to be used as the *main* return path for current, neither for normal conditions nor for line-to-case faults. It’s not a SWER (single-wire earth-return) system.

@JOHNDANIEL1 6 месяцев назад

What your referring to is Common / Neutral and ground Bonding. A process is to increase the speed and safety of the circuit breakers. By doing so you get the line ( hot ) less able to default the energy into a identical size conductor ( neutral/common). Just do what 3 teens in Dallas did, Walk up to a few dozen poles and chop the "non circuit" ground wire. See how many smart meters responded back to the utility with shut down request. Then it was over 200 of them. It is a part of the engineered design to promote the center taps balance and return. When we installed over 130 massive wind turbines in the Texas Panhandle, western Nebraska, and most of southern Idaho from 2005 to 2008 the swash control switch on the transformers readings came solely from the ground cables. Not the HVT or the TRC. A simple test used in the past was to connect the hot line to a ground directly to check the amp draw before circuit interruption. If Ground was not or never a circuit, it would do nothing.

You only need to understand George Westinghouse and Nikola Tesla to understand why the ground is used in generative energy. en.wikipedia.org/wiki/George_Westinghouse And the process is same now as then but we went astray on why so much is to be "grounded" and what it means. They all ( the professionals ) seem to connect electrical generation "ground" with Lightning protection "ground" and compound it and the problems by joining the 2 as the same. They ARE NOT!!! Same name, different outcome. For mechanical generated energy you must use the ground as a balancing design due to remote used transformers. With Lightning using a ground is creating a unnatural pathway for lightning to pass through what ever you ground. Centuries ago a lightning rod was used and not placed near homes, typically placed on a barn or other and consisted of Irion from height to depth in earth due to its innate chemically connective history of lightning preferring high ferrous oxide containing soil (ground) to strike. Go figure, 350 years ago they knew this!! And they not would have connected to a shared ground rod with your utility system. But 85 years ago a drunk code writing bureaucrat was born to change it all!

@Joey-kv6qr Год назад

Yes by code anything that has conduit on the roof of any house needs to be grounded this includes solar panels. The key is to that it needs its own separate ground do not use the same ground as the utility. Its just a lot safer for solar panels to have its own ground wire if they are on the roof. If lightning does strike the solar panels on a roof its just better for it to be directed to go towards ground. If the solar panels do not have ground it will most likely follow the wires towards the batteries and destroy everything connected to it, but I'm thinking that will happen regardless if its properly grounded or not since lightning is incredibly powerful but its still a lot safer to ground the solar panels. Flexible solar panels do not have conduit or aluminum frame those will not need a ground. Also while its rare its not impossible for a lightning to strike the top of a car even if it has solar panels or not, for the most part you will be safe because if lightning hits the top of RV the shell of the RV will become energized and go towards ground thru all 4 tires - you will definitely still have a lot of electronics fried up though regardless. You just have to hope lightning never strikes your car or roof & never park under a tree when its raining. I'm thinking since inverters will never have a surge it won't need a ground to send that surge to ground, maybe only if it gets a lightning strike but again if a lightning strikes you'd most likely need to make major repairs to home for weeks you just have to hope it never happens.

@JOHNDANIEL1 Год назад

The real cure is remote higher targets like lightning rods. Or placing solar on metal roofs. Using metal roofs makes it where the lightning discharge is so expansive that it repels into atmospheric static. No single point collection or dispersion. In test of a AC unit on a roof of a building, the one on wood framing was destroyed by lightning, the one mounted on a full sheet metal roof had its relays damaged. Not allowing the 1 mm wide arc of lightning to concentrate all its energy into one square foot of discharge weakens its ability to do damage.

I'm not here to diss you. You, as a man and a father just recently gained my respect. 😊 But... you do seem to be a little confused in regard to electricity and electronics. I will not start blabbing about my experience but: *Grounding* in any electrical circuit is a protection feature. In AC systems it can also properly protect us from electrocution. In DC systems, grounding protects the electronic components and protects us too from loosing cash, housing, life and limbs. There are three main big dangers in solar power systems that can be reduced with propper grounding: Electrostatic buildup - your panels and cables mihht be high-up somewhere and if they float (electrically) in regard to the ground, they can acumulate really big electrostatic charges. These can really damage electronics even if it can't pose a (direct) life or health issue. Faults and EMI/RFI - now these won't work in impropper instalations but, in general, poropper grounding and propper overload protection systems can prevent electrocution, electrical fires and radio interference. Induced surge currents from lighthning strikes - now, if your system is struck by lightning you're screwed, period. But if the strike is not direct, dangerous currents are still induced in your system. The later can be adressed by propper grounding and propper protectiin circuits. The ground is a _third_ conductor in any circuit. It is the conductor we humans are in contact with. It is regarded as a neutral refference and usefull in fault detection and mitigation. As anything else on this particular planet, impropper grounding can do more harm than good. Stuff that is high-up should be grounded or have pathways to grpund for surges. Stuff that can leak currents on the outside sould be grounded.

@JOHNDANIEL1 Год назад

Not confused one bit, but if grounding solar panel frames is important to you, do it. Grounding unpowered things that are on everything will need a few trillion tons of copper. Argument being equal, unless its to be cherry picked to eliminate inconvenient facts. See you at the aluminum skylight grounding party.

Let me tell you about a personal experience I had a month ago. I lost $5 worth of equipment but that is not the point. My pv system at my new home is currently under construction. Nothing fancy or big, just 1.2kw of pv on the roof. The grounding and suppressors are still work in progress and I forgot to disconnect the array when I left for a while. There was a storm, not much but with some lightning in the area. The house was disconnected from mains, the charger was disconnected from the battery but still plugged in the solar array. One digital voltage/current monitor was fried. Nothing else but if the esd/surge protection box would've been grounded (and populated with the appropriate IGDs :)) ) nothing would've happened. Stay safe. The costs of grounding and protections are no match for the costs of property, health or life.

If lightning were to hit your solar panels, there would be a severe amount of current that would be best served going through a ground wire into the ground, then trying to find another path such as going into your equipment, destroying it. That principal is quite simple. Additionally, power created in the power plant runs through the hot wire and goes back to the power plant on the neutral. The ground is not part of the circuit as you as you inappropriately state. In the event that the neutral got severed, and therefore the power needed to return back to its source, that is why the ground exists. To give that current a place to go. Also, whether you're on or "off "the grid, people still have to pay property tax and abide by local codes. So get yourself a piece of wire and a grounding rod, and do it the right way . Now I will add one caveat. When it comes to "required "grounding that is only for systems that are over 50 V. If you were in your RV which is a 12 V system, then obviously a ground would not be required. Even if you were running 48 V and then stepping that down to 12 same principle, but once you exceed 50 V you're not going to want to have any accidental current, running through you as you step out of your RV onto the ground. ...

You do not understand electricity. For one, Airplanes have NO ground rods their bodies pass lightning around the shell out to the earth, but they have a 60 volt DC electrical system. Ships have a 36 volt system under 9 meters, 72 volt dc over 9 meters, and no ground. Solar panels are not connected via their metal panel frame to the +/- of your DC circuit, no matter from 0 volts to 1500 volts. The only way you will enhance, or migrate a lightning strike to you is by using a ground. It's called a Attraction. The only way you will energize a piece of aluminum, whether on a solar panel or on your work bench is with a ground wire, not by letting it stand alone. The standard Metro Overhead has up to 4 hot wires, Rural usually 2, a active and second active and NO NEUTRAL. Only one hot goes to a transformer on split phase, 2 do on 3/4 phase. They are All hots unless it is industrial and designed to be non standard. The years we worked for Siemens Electric building huge wind turbines we never had a "Neutral" in any transmission lines. Top wire on a pole is a ground, not a neutral. It is connected to a ground on every pole, not a neutral. ***I jumped the paint and pictures part of this General Electric training video to get you to exactly that GROUND that is part of the circuit you claim does not exist.

And the GTE Transformers wiring diagrams. So this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xMZkKI5rleg.htmlsi=PNLDp7lmDTt5FwVL also with details on that "circuit" of ground, neutral created via ground, also details it. Still, not a neutral. A neutral is a ground, it returns to the Transformer ground post, not a overhead or underground feeder, but to the ground matching tap ( top wire & solid 13 coils on end of pole 6 awg rural, 13 coils of 4 gauge Metro Ground tab/cable) A neutral is what your making from the house, to the transformer in response to create flow, not from the power plant to your house. That is why when you "bond Neutral and ground" your only adding short circuit support to the mains.

You ground the panels NOT for lightning strike protection! That is an entire separate part of the NEC code for that as discussed by mike holt. The reason you ground solar panels is that when there is a near strike, your metal parts will INDUCT voltage that needs to be dissipated to ground. You can see this on metal roofs exploding and arcing to ground when a nearby lightning strike occurs from induction. There is video evidence of this and it causes fires and also causes damage to your panels if you didn't ground them. Its not about return neutral to earth voltage like AC, but its about dissipating induction voltage, that also why Delta three phase ungrounded systems were phased out from equipment failure due to inductive currents jumping across equipment.

@MrRLPhoto 9 месяцев назад

*also forgot to add this, safety equipment that protects against Arc Fault on DC current, which you know does NOT extinguish itself (Gain solar vids on this) Need a ground connection to the Negative DC solar connection. Then you use GFDI type breakers to detect if your solar array is arcing somewhere causing a fire. Grounding is important but yes, it is not quite the same as AC grounding.

Inverters for US market most all have markings of B or L for line ( black on romex ) W or C ( white on romex ) and a ground G or E for earth on them ( bare wire on romex.) Using a ohm meter you can check inverter chassis to find ground on those terminals if the markings are screwy China based done. Otherwise the inverter is not a utility level voltage, its a simulation so you will get voltage, trace responding voltage, a ghost basically, like in your test but not always actual output. Not sending out amps. As for wire color, I would not base your safety on it. Consider all hot. But if you really want a simple solution, you just power it off, remove battery, power switch cycle it to drain any power inside, then do a test on the outlets ( continuity testing ) them match and mark the proper ones. On the outlets you will have ( wide blade is common white wire, narrow is hot line black wire and ground if connected inside in the outlet is the ground post.)

⁠"expands conduction". No, Iron oxide neo particles in soil, reduced to carbon. And therefore it does not promote conductivity in the soil. But you go ahead and get somebody electrocuted in a "tragic accident", because sometimes that's what it takes for a person to change their opinion.

You got a lot of work ahead of you on Iron then going out warning all the Cell Phone companies who use it, the AM radio stations since the 1920's who use it, and the hydro electric dams that base their system on it. In fact, a few hundred million use it in their homes as ground rods. It's 1.2 mil thick copper plated high iron steal rods you buy at Home Depot. Iron in the ground will turn to a number of minerals over time, about 8,000 years it's man altered refined state can be a large amount of carbon. I really don't expect to be in that era discussing it though.

Treat your inverters as a island and it will run right. And you won't put wild voltage from refrigerator/air conditioner and transformer feedback into your solar either.

@johnbrizendine7716 Год назад

You are completely correct on the grounding attracting more static and lightning, though, especially with solar panels. The only reason I ground anything is to prevent static and electromagnetic interference, but on a solar system I always use a grounding wire with a spark gap so that it does not actually give it a ground, but with the spark gap, it will give any large static buildup a path to ground via the spark gap without actually being a ground in and of itself. I do the same with my ham radio antenna arrays and tower, if it is directly grounded, it will cause a standing wave or directly conduct the radio waves to the earth, but with a spark gap, it will allow any dangerous voltage or static charges or lightning to jump the gap and go directly to ground. A long time ago I was putting up a temporary antenna array, and it was not very high up at all, and I didn't run the ground wire/spark gap combo, and for some reason there was a LOT of static built up in the air around it and when I was running coaxial cable I got quite the static discharge, it hit me pretty hard, just glad it hit me instead of the repeater I was configuring. Flesh heals and bones knit, but semiconductors burn up. For my most expensive gear, I always use an isolation transformer and a completely separate the ground from the rest of the electrical circuit to prevent unwanted interference from the electrical grid, while preventing unwanted interference from other emissions. Grounding and how to implement grounding and knowing what to ground and what not to ground is a very VERY complex subject, depending on what equipment you are working with and if it isn't done properly will cause more issues and cost more than you could imagine. I do use TVS devices and chokes on the incoming lines from my solar panels, just in case something comes through that may damage my equipment, as well as smoothing out any ripple caused by the fast switching semiconductors in charge controller. ( In my opinion, you can never use enough chokes when wiring one component/device to another. ) The chokes to prevent small spikes and the TVS devices because they are not a conductor except above a certain voltage threshold, so it will not be a path to ground until just after it gets hit. Won't attract the discharges, but will dissipate them if they do happen to hit.

Great discourse! Why build an Electro Magnetic Pulse magnet to blow up your own stuff! Your spark gap solution is brilliant!

@JOHNDANIEL1 Год назад

I install on METAL buildings or metal roofs, I argue with lots of people telling them to use metal roofing as a install base. Now the why: You are 27X more likely to get a antenna on a chimney struck by lightning than a metal barn roof. Wonder why? Mass Squared. Lightning is 1mm in width, looks huge, thats the light. But it is seeking ground resource to build from. A large metal roof takes that charge and equalizes over volume of area. But a single antenna on a chimney gives it concentration to arc up. So, mounting on metal makes your panels less of a pinpoint target. I build ( making video later ) a array that uses metal roofing panels, that is why I got so much laying around here. Using lamination cross link methods. Very strong, very lightning resistant.

@@hellandbackhoe Electrical current runs perpendicular to electro magnetic fields, so if an electromagnetic field passes over electrical conductors, it generates some current and can cause voltage spikes and unwanted interference, so by putting a choke on all connecting wiring, it will literally absorb that extra current/interference (see faraday's law). Not sure what you mean by building an electro magnetic pulse magnet, though. The spark gap concept was widely used from the 20's through the 50's for protecting sensitive electronic equipment and preventing lightning and static discharge damage.

@lassewestvanghougaard4856 Год назад

John, The reason why solar panel FRAMES are grounded... Is NOT to protect the solar panel from lightning damage. It is to protect people that have a path to ground with their bodies. Electrical heat, Any energized conductor can melt and short with a solar panel FRAME, and this is the main purpose that enclosures and fixtures are grounded. Volt DC is just as dangerous as Volt AC (Although you could argue that AC being pulsing can hit you harder due to the oscillation) The higher the voltage, the greater electricity conducts with the human skin, and the longer the electricity can jump through air molecules. 12-48VDC (Less than 50VDC) is considered safe for mobile devices without needing grounding of parts that are near the solar FRAME because the resistance in a human body is high enough to prevent current from traveling through our limbs. For solar panels connected in paralleled, ground is not needed because the voltage does not exceed 48VDC. if you connect solar panels in a string configuration between 450-600VDC, we are dealing with voltages that considered "Medium voltage", and is capable of locking a technician/installer to the FRAME if there was a direct path to the solar panel current carrying wire. Now the current will travel through the human body all the way down to ground, however the path is established. Be very careful with voltages higher than 50-120VDC and up! Don't let your DIY project be the end of someone's life.

@JOHNDANIEL1 Год назад

Nice try. But why would a proper installed wiring job lead to such calamity? You can ground your roof too, and your carport and your trees. Lots of power lines near them too. OR Use fuses like the manufactures instruct you to do, then no matter what you do while improperly wiring your solar with under gauged risky wire to 600 volts you will not have a continuous hot short from melting crappy under rated wiring and work. **Solar frame grounding is for as described by manufacturers, solely as lightning protection not DC shorts to earth ground use. Installers have pushed this DC ground lie to the profit of a billion dollars. Use proper wire and fuses LIKE YOUR CAR DOES or even like Cellular power systems of 250 VDC transceivers uses and you will not have a issue to ground your DC power to itself or the earth.

@lassewestvanghougaard4856 Год назад

@@JOHNDANIEL1 Also, grounding your light fixtures isn't necessary in all cases either. However, it's a good idea as it makes your light fixture safer and reduces the risk of injury. I don't see how a 500-600VDC solar array is any different. (And 100% of regulators will agree with this point) If you don't want to be regulated by a "electrical professional", go ahead and keep your solar panels ungrounded.. The likelihood of 500-600VDC leaking into a solar panel frame may be very minimal. But the fuse won't trip if the Amps doesn't exceed 15A that the panel is rated for. The body has enough resistance to not exceed 15A. And I have a gut feeling that car manufacturers use 250VDC transceivers need a higher and stricture insulative regulatory guidelines in order to sell them. You can even submerge electrical equipment with the right NEMA/IP rating, I'm not saying that solar panel fabricators can't make products that are fail proof. But I don't think that most solar panels are UL listed coming from Korea/China.
