Solar Panel Wiring vs Volts and Amps 

Thank you - great informative video series. Maybe discuss the affect of the sun shading when hits the panels in "series" vs. "parallel" and then vs. "series/parallel" setups?

These are incredibly helpful videos brother! Thank you for sharing your knowledge.

Just keep watching again and again. After about a year you will start understand enough to at least ask questions

Great videos. Which configuration would charge a battery fastest? For example, does wiring it with higher voltage but less amps result in slower charging due to lower amps, or does the higher voltage increase the speed of charging?

The quiz was great. I failed before your presentation, and passed after. I appreciate the work you put into the videos and the quiz.

Finally someone explaining not just the maths, but why you’d do it. I’ve been looking for this info for a while. Great job.

Oh my! I’ve had sooo much trouble wrapping my mind around this! Thanks so much for the simple video. I learned so much in 10 minutes!

This is EXACTLY the video and information I've been looking for!!! THANK YOU!!

How could it still be confusing after the amazingly great way you’ve taught this. The combination of your succinct and accurate words alongside visuals was the best I’ve seen yet. Thanks for all the time you put to this.

So if I have a 400w, 80v, 5amp system, would it only be storing 5 amps an hour to my batteries or would the controller actually put our more than that when it transfers over?

I love ur way of explaining the dif panel configurations my question is when looking at the back of my 4 240w 37.2v panels i see 4 dif amp ratings im trying to figure out witch amp rating to go by 1. Maximum Power Current 7.89amps 2. Short Circuit Current 8.73amps 3.Maximum Serious Fuse 15amps 4. Minimum Bypass Diode 15amps when wiring witch amp rating u referring to ? thanks

Good Morning ! Does this mean i could use 9 gopower 190 watt panels in 3 arays and work with the 10 ga wire all the way down to a victron 150/100 controler ?

This series is fantastic! Some of the info you cover I already knew well, but I still fully enjoy watching. Even if you don't plan on doing any of this stuff yourself, if you own a solar system, you owe it to yourself to watch this series so you can at least understand what is going on with it. Great job Nate! Kudos!

Im having a bit of trouble with my system. I have everything set up but my charge controller even tho it's setup in direct sunlight the charge controller is stuck in night mode.

Thank you! GREAT explanation video. Much appreciated.

Thanks for th very helpful video. I have followed your video to installed my solar system on my van. I have installed 3 210 watts of solar panel parallel with Victron 150-70 TR smart solar controller with 50Amp dual pole breaker. now My breaker gets very hot and trips the breaker after a while. I have used 10 guage wires per your instruction. Any inputs? Thanks

I was hoping you would address the function of the MPPT charge controller in how it coverts the surplus Volts into Amps and what the math is or how efficient the conversion is. Also, how the panels function when one panel is in shade and how that effects the output in V and A in Series vs Parallel.

Thanks for the awesome video. I am looking at 4 x 200W solar with a 27W VoC rating per panel and 9.66A output. I have a 100/50 Victron MPPT and with this setup in Series would exceed by 8W ( ie:108W) - will this still operate OK in series without damaging the solar controller or should I use the series / parellel solution to obtian 54Voc and 19.32A. Love the Videos !!

Very important info, Loved it ✌️🇺🇸☮️🗽

Thanks for the video, thanks for the channel. This is the first video of your's that I have seen. The Google algorythm suggested your channel. Sounds like your channel is exactly the channel for me. Just bought a house where I will be building a workshop for building out a camper van soonish. Thumbs up and a subscribe from Charlotte, North Carolina. And yes, I will be making use of your pop-quizes. Better to fail a quiz, than start a fire. : )

The only confusing thing about all of this is which one is best to charge your batteries? When living in the van, you’re using amps, and concerned with how many AH your bank has. Do you want to push the most amps into the battery, or the most volts into the battery? Nobody bothers to tell you which is actually preferred or which will charge your batteries to full faster. Could you please cover this?!

Hi, pls can u do a picture diagram video on how to connect solar panels for a 48v system (Number of panels and how to connect them together (280w ,300w, 325w or 350w 24V)

excellent video, extremely informative! thank you explorist

What if I array is parallel and the other array is series ...Then combined them is it possible..bec in series volts same amps added 1st array THEN 2nd array parallel volts same And amps added ..So the first array different volts and amps ...Likewise the 2nd array different volts and amps .

I had my panels in parallel. Changing them into series-parallel really increased the amps into the batteries. My voltage into the charge controller was too low. Increasing the volts increased my amps. Thanks a ton for these very useful videos!

I really liked how you explained this, but I have just learned that there is a schematic to the panels which includes max. power, max. volts, short circuit current and open circuit voltage. When you were giving your diagram at the begging, which are you using. My 100 watt panels don’t have the same numbers that you used and I understand that can be important. None of my numbers were whole numbers and the multiplication didn’t work. Thank you!!

Outstanding informational video Again! I reviewed this video 4 months ago, but it didn't sink in until I actually had the solar panels set up. I am humbled by your knowledge and help.

What about the mppt max PV input power? I have a 20amp mppt Nominal system voltage 12v/24v Auto work. It has a Max. PV open circuit voltage of 60v. It has Max. PV input power of 260watts (12v) and 520watts (24v) Im confused about how much this mppt can handle. If my panels are configured at 24v and battery is at 12v. Can I go with Max. PV input power 520watts (24v)? Or is this referring to the battery needing to also be at 24v? Thanks for any help. After seeing your video another question arose. Shouldnt my mppt be able to handle 60v x 20a = 1.2kw(1200w)?

Your are incredibly helpful and this is by far the best video out there I've researched for helping to understand how to not only connect panels but in the best way. I'm about to put together my 6 panels to my bluetti and I'm actually excited because I have much more confidence now from your very clear tutorials. Thank you so much!!!

Hello, great video! I need some advice, I would like to know how much solar panel and how strong does my battery and converter have to be to run a submersible water pump. Also how strong dies the inverter have to be to work for a water pump. I only need it to run about an hour per day. Let me know please.

sie is 0.5 A IS SUFFICIANT TO CHARGE 3A BATTERY THROUGH 30 A CHARGER CONTOLLER

Man I am still lost and watts law doesn't add up I have 8 - 200watt panels (24.3 Open Circit Voltage VOC) & Maximum Power Circit IMP 9.80A... I have a 150 Volt Maximum HOW would I wire this and have it add up to 1600watts and stay under 150 Volts??? Thank You For Your Help my mind is mush getting old stinks.

Cheers for the video! Great as always. I'd like to pick somebody's brain on something. Can I use 50 mm2 copper cable to connect together a 48v energy bank (8 batteries) and then to the inverter? I have this cable so I may well use it instead of buying a thinner one. But, being a layperson, I wonder whether, perhaps, this will result negatively on the efficiency/ efficacy of the system ...? Well, that was actually a question in case somebody has an idea.

Hello from 🌞 Arizona. I have a ECO FLOW Delta Max Pro with solar imput maximums of 15 amps, and 150 volt max. Could you please tell me the max setup with 100W 24V panels, looks to me like most in series to keep the amps under 15A. Thanks SO MUCH. 👍

420w panels x 12 panels. Series parallel setup 4 panels in a series. Total 96 Volts 52.5 Amps. Which gauge wire to the charge controller from the combined box?

Hey man I am in a problem . I got 2 Q CELLS Q.PEAK DUO BLK-G5 315 And 1 Epever MPPT Solar Controller 12V/24V Charger 150V Controller+Meter Tracer4215BN I am assuming my sistem is not compatible 48v to 24v controller . So could you make a video how to separate the solar panels from 48to24v . A guy in this platform separéd a 1p24v to 1p12vx2

you are awesome!! this is the most I have understood anything about solar so far. for clarity, i have a 1500w array of poly- rigid panels. i have been going crazy trying to figure out how i can hook this up on my bus. so I think I got it with this video. they are 250w panels. so i am looking at connecting them in series 2, 2, 2 (total 6 panels) and then connect in paralell and use two 100/50amp controllers... is that correct?

Thank you so much for your great explanation. Thank you for sharing you time and knowledge. 🙏💪

Wonderful explanation. I have a question which I think you already answered but I just wanted to verify. My Victron MPPT 100/50 controller sometimes turns OFF, stating Insufficient PV Power, and that PV must be at least 5V above battery power (12V LiFePo 3 battery bank). Today battery voltage was 13.8V and VOC was ~17V. I'm in Utah in the summer and this happens sometimes for 2 days at a time in sunny weather. My two 220W NewPowa solar panels are wired in parallel, with a VOC of ~20V. It seems like I may need to rearrange the wiring to connect the panels in Series, raising my VOC to ~40V. Does that sound correct? Personal note: I find it amazing that you actually put in the effort to answer all of our questions and I find some of your answers hilarious. Keep it up, please!

great information. Many thanks

The solar that came with our boat uses different size panels of on known voltage and watts. Guess I can measure the voltage at the controller. My question is I want to add 4 identical 100 watt panels to go to my house bank can I just wire them in separately using a parallel, series connection then go thru a separate controller and everything including the existing solar panels into my house bank? Is there a better way? S

I need to wire 8x 370w 45.69 voc, 10.30isc panels in series parallel with a voltage of 102v and 52amps. How would I achieve this? What size wire do I need from the panels to the mppt charge controller?

Question about a JP21-19/900 - 72VDC, 900w, 1.2HP, 62ft, 92GPM, Solar Water Pump with MPPT Controller - I have 4 x 270watt @ 35.5v Solar Panels. Will the controller handle 142 volts coming in and deliver the required 92v if connected in series? Or will I have to connect 3 panels in series and 1 panel in parallel to them? Or possibly 2 pairs of panels in series and then connected in parallel? I would like to use all 4 panels if possible??? Thank You for your expertise.

Hi, thanks for the nice, simple and educative videos. Series or parallel? Which one can charge the batteries faster?. Thanks in advance and greetings from Gambia

Hi Nate, After reviewing many of your great videos, it just doesn’t look like there is a “great” alternative for our 75% of-the-time cloud shading, on the coast in Alaska. Tried to subscribe to your private group, but it was not currently available, so I am hoping that you will be able to make the time to respond to my question. Option #1, Hybrid Parallel: (Four total, 120w panels, 6.79a, 17.68v each panel) 2 separate, 2-panel systems, each parallel = 17.54a, 17.68v each system (BUT inadequate voltage for 12v battery power storage minimum and mppt efficiency). Option #2, Series: Single, Four total, 120w panels = 6.79a, 70.72v (BUT “series” reduces all panels to lowest during “75% of-the-time” cloud shading). Option #3, Hybrid, Series-Parallel: Four total, 120w panels = 13.58a, 35.36v. (BUT 35.36v is probably still inadequate for 12v battery storage and mppt efficiency, considering “75% of-the-time” cloud shading). Leaning towards "series", but what am I missing? I can't say enough about all the great help you provide! Thanks again. Dave M.

I have 36 250 wall panels with specs: Rated Power: 250W Open circuit voltage (VOC): 37.6 V Max power voltage (VMP): 30.3 V Short circuit current (ISC): 8.85 A Max power current: 8.27 A Power Tolerance 0/+3% Maximum system voltage: 600V (UL) Fuse Rating: 15 A Ideas on how to wire this to keep costs down? Area will have very little if any shading.

What if.....3 panels 20/5 arranged serially will be 60/5 and 2 panels 20/5 arranged serially will be 40/2... if we arrange 60/5 and 40/5 parrellely..what will be the outpu

So if I have 6 panels 195W Mono Solar Panel Open-Circuit Voltage (Voc): 22.8V Short circuit current (Isc): 12.23A Working current (Iop): 10.27A Size: 1480*668*35mm（58.3x26.3x1.4 in） Weight: 28.2 lbs (12.79kg) and a 4-String Solar Power Combiner with a 60A solar controller - how would you recommend hooking it up ?

Can I ask which method will charge my batteries faster. I could pull it apart but would appreciate some feedback. Thanks for the great vids

Not sure if I missed it somewhere, but the calculation of V to the MPPT shouldn't that be using the VOC figure not the nominal V panel. Ie my Winaico 260W 20v panels actually have a VOC of 37.9V according to the data sheet. That makes a huge difference in potential voltage supply at the MPPT. (I Think) Can you clarify that for me Nate.

Hi there, great information. I have a question, I have 2 X 100 W panels connected in series going into a renogy rover 20amp charge controller. I am charging 12 volt lifepo4 batteries. I'm getting 35-40 volts and 9ish amps so around 350 Watts and this shouldn't be happening, I don't think the amps should be doubled so is this the MPPT increasing the current or do I have another issue?

I have four 200w panels wired in parallel like you have at 4:02 in your video. But my Bluetti AC300 shows only 180w at 22v. I was expecting around 800w. What am I doing wrong? The panels are Renogy RSP200D. Open Circuit Voltage 27v. Short Circuit Current 9.66a

I have 3x rich solar panel 200w 24v (Voc) 45.4V (Isc) 5.83Ax3=17.49A . My inverter LV2424 MAX PV INPUT (VOC) 145V, I'm using paralel connection so my (Voc) volt will stay the same but my (Isc) amp will increase can my amp can go more than what it shows in the chart? I need help for this thank you in advance

Can I use a 200 watt solar generator to charge my 2000 watt solar generator? The Anderson input jack stopped working on my 2000 watt, and I'm boondocking so can't use shore power. The only other input port/jack on my 2000 is a 3 prong plug. I can plug it into the wall of my RV and turn on my coach generator (gas), but don't want to and it's noisy and shuts off before I get much charged anyway. TY

Love your videos, very helpful!. I have a victron 100|20 in the caravan with 2x 120ah lithium. At the moment I only have one panel but I want to add 3 more, each panel is 160w, and put out 8.74 amps each, the regulator has max charge output of 20amps am I best to wire in series to increased the voltage and keep the amps the same. The VOC of the panels are 21.9v Series 21.9v x 3 is 65.70 volts With 8.74amps I've never delt with wire in voltage, only I'm amps, what size wire it's best suited for 65 volts? I'd like to wire in series parraell mainly for the cable sizing but it will mean I'll need to upgrade my regulator

Thanks for this great video and giving back to the community! If u dont mind, i need some advice on my config. I have a goal zero yeti 6000x that can take an input of 600w 14-50v 50A MC4. I have 4 sharp solar panels at Pmax 140w, Poc 24.85, Isc 7.81. I was thinking of doing a series parallel that shud get be to 560w, 50v, 15A. Use a power joiner and 10 gauge wire to my yeti. Is that sound?

I have a customer who can get 14 200watt panels on his roof...... help.... advice please.... 2800 watts. 8- 12v 300ah lithium batts.

This is a question of charging efficiency, not cost-efficiency. The goal is to gather as much sun as possible through out the day on a small system where roof space is very limited. The system will have only 240 watts of panels. Since the Victron MPPT's state, they don't activate until the solar panels are providing 5v over the battery voltage, more panels in series will get to that voltage quicker. The question is, how much do you really gain? One setup is using the 100/20 with four 60 watt panels and the other uses six 40 watt panels with the 150/35. How much more efficenct would the six-panel system gather over the four-panel system? (maybe this is a video idea????)

Nate, Can I wire 3 panels in series parallel? I have three 315 watt (9.41 amps * 33.46 V) solar panels on my van roof and a Victron MPPT 100 / 50 smart solar? My battery bank is 600 ah Battle Born. Thank you for all this very helpful information!

Great video!! Silly me should have watched this before wiring my 3x solar panels in parallel...wondering if you would know why my setup only charges at 6-7amps with 3x 120w panels wired in parrallel with dual batteries sitting at 12.2v (drained on purpose)? Renogy 30amp MPPT controller. Thanks

So my array is 16 250 watt panels, 4 strings in parallel. The current @ pmax is 8.27. The volts @ pmax is 30.3. Open circuit volts are 37.6. Not sure which volts to figure but i guessed the 30.3. Im coming up with 121 volts and 33 amps. Is that correct? Then im shopping for a charge controller and they all say 12v 24v 48v etc. What size charge controller do i need? And inverter as well? Its not too confusing but im brand new to this and i cant afford to screw it up. Thanks

Good vids. I had an issue with my controller showing 0.5-1.5A Individually tested 4x120w 12v panels each giving 4-5A. Reconnecting cables and y cables in parallel whilst testing and was getting up to 12A (due to sunlight changes) But when connected to controller it showed 0.5-1.5amp Found draining power from the batteries caused the the panels to draw more current going up to 9.5A and today even to 16.5A So be aware if your batteries are fully charged they will trickle charge and draw less power.. But by connecting power tools, diesel etc to drain the battery it caused the panels to draw more current Hope this helps

I haven't seen a Solar set up using a Yeti Goal Zero with decent solar panels other than what Goal Zero provides. Could you do a video showing how to maximize the availability for a Goal Zero Yeti 1000x battery? Currently I have found that the unit has a built in charge controller that can handle 50V, 50amps, and up to 600watts of power. Any chance you could show the best set up for that?

I just installed 9500 GPH sump pump for a fountain in my 1/2-acre pond. I have 2 100Watt 12V solar panels with 30amp controller and 600-watt inverter and 3 lithium batteries 12V 20aH. Unfortunately, I'm only getting 8-10 minutes per hour of run time before the alarm goes off and shuts down. Do I need to add more panels to accommodate or add more batteries or both? Should i go with 12V 100aH lithium batteries over the 20aH that I have or add 2 more 20Ah. Which is best for panels and batteries series or parallel?

I have (8) 12v 100 watt solar panels, a 150v max 12/24/48v MPPT charge controller 24v split phase inverter and (2) 12v 200ah life po4 batteries in series for 24v. In what configuration should I wire my panels? I thought I had to wire my panels to equal 24v like my inverter and battery bank?

Hi Nate, (dumb question coming) I'm looking at a lithium battery's, and they have a minimum 40amp and max 70 amp charge..... So..... For these batteries to be charged up at the 40amps, my entire solar array would need to produce a minimum of 40 amps.... Correct? This is going to determine how I complete my entire solar array wiring. Thanks much!

800W in 4x200w renogy solar panels, Voc 27V, Isc 9.66A I got the renogy 60A mppt. Should I go 2S2P? I can't even find a max volt input on the controlleras it states its max is 800w, not volts. DAFUQ?

I guess I'm confused on how to read an MPPT controller in the first place. Some aren't as straight forward. I have a Growatt 48v 5000w inverter in mind that says "PV Array MPPT Voltage Range - 120Vdc~430Vdc". Does that mean the solar voltage should be between those two numbers for optimal usage?

When you lock at victrons specifications for smartsolar 100/20 mttp regulator it says nominal pv power at 12v, 290watts. What does that mean? I should get 2000watts of solararrays before I max out the regulator if calculating with your metod (best case senario, 100v at 20a?). But victrons mttp calculator goes from 100/20 to 100/30 when i add two 115w in serien time two in parrallel. My count it should only be 40v x 16a? So should still work with the 100/20 right?

I have 5; 340 watt Adani solar panels. I have a 48v Hybrid 3500w pure sine inverter 80 amp mppt controller. The Adani panels puts out 38v. 9a. The controller says it can handle 65 to 115 Vdc. What is the best way to wire the panels. Series is the preferred, being an mppt controller. Will be to much voltage though. Parallel? Or series/parallel? Maybe use less panels in series? Not knowledgeable to figure the best combination. Thanks for any answers. My name is Bill.

Im a bit confused lets see if anyone helps me... i did the cables in parallel and i get 30v, 20.3 a, 727kwh, with the battery being at 27.7v, 21.9a, then i swiched to series and i get 90v, 2.8 a, 727kwh, with the battery being at 27.3v, 9.4a.... is a small room with a small fridge, tv and fan and a few light bulbs... which set up should i use?

I get that you receive 120V/5A or 60V/10A depending on the setup... but the battery still receives 14V, yeah? So, the amps would be the same whether you do it one way or the other? But you save money on a cheaper MPPT, smaller gauge wires etc? Have I understood it right? :)

Hi mate, I just discover you. So, I ignore if you've already done about this : What about the theory saying that you take the number of watts of your panel and divide it by the voltage of your system to get the max amp that your charge controller can support? Means : 195 w ÷ 12 v : 16.25 amp. So if I have 6 panels, I need a charge controller with at least 97.5 amp capacity? Is it a true or false leading? Thanks a lot!

The MPPT says 100|50, what is the 50? And is that the AMPs from the Solar Panel or the Amps going to the Battery? Here is some more in the way of example: Say have 250W panel at 50V and 5A. Now if I go to a 12V battery, the Amps going to battery is about 21 Amps. But if have 24V battery, than you have about 10.5 Amps. So when sizing and looking at the Amp rating of charge controller, do you need to take into account battery voltage or do you just size the amps from the panel?

Which amp and volt numbers do I use for calculations? For example: for volts: VOC, VMP, or max system voltage? And Amps: Short circuit current ISC, Max power current, or Fuse rating?

So series keeps the amperage low so you can use smaller cables but increases the voltage so you need a bigger charge controller. Wiring in parallel increases the amperage so you may need bigger cables, but keeps the voltage lower so you don't need a bigger controller. In my setup, i'm working with 4 215w panels which i'm going to wire in 2 groups of 2 panels. That'll mean i could go with the 150/35 VE MPPT controller and not have to jump up to the 250. Now to figure out what size wiring i'm going to need..

hello, Please i have question 3 questions, I just got 2, Newpowa 180W (watt) 12V, and I'm having a hard time trying to choose a solar controller, batteries and converter. which solar controller will work best for me? and which battery and converter ? please hellllpppp 🙏💫

I have 4 100 watt Renogy panels coming down to the Victron 100/50 MPPT wired in series/parallel for 48 volts. Only get around 170 watts during bulk charge. Should I wire them all in series to see if they improve? How do I test for a bad solar panel? If they are all in series, does one bad panel cut off the entire array?

Thanks for the great tutorials. if I have 6 200 watt in 3s2p configuration, the amperage will be apx 20 and the volt are just over 80, will I need to fuse the positive to 15? I bought your diagram and I didn't see any fuse. Thanks

Hi, I’m new to the solar systems, I had a thought, I will be using 6 x 12 volt x 200 amps sealed acid batteries, I will be using 100 watt 12 volts solar panels, is it better to wire the panels for volts or amps ( obviously, keeping within the voltage rating of the inverter/charger box) thanks for your help. 😎🏍

Please help! I'm fitting 4x175watt 12volt solar panels on my van. I'm going to have 2 x agm 110amp batteries. Please tell me what size mppt you'd fit? I was thinking of having 2 in series and 2 in parallel? Please give me your thoughts on weather you'd do the same. I don't want break the bank over buying a mmpt. Thankyou in advance and you videos are the best! Simon London UK.

Nate I was able to get 150/100 MPPT Victron charge controller at a really good price from a friend but still confused on the best way to connect (Six) 100 watt panels using this charge controller because I could hook them up in series and still not reach 150 volts or I could hook them up Parallel and still not reach the 100 amps. Should I just hook them up Series Parallel and never give the charge control a real workout? How would you do it? Is using the Victron 150/100 a problem with my 600 watts of solar and 400 amp hours of batteries? Thank you for your videos I fall back on them all the time I need a refresher.

Before I send this panel back I bought a 24volt 200watt panel I will have 4 of them. I want to wire them series parallel My battery is 24v 200ah Should I use 4 12v 200watt instead.?? Is it possible or ok to connect 48v to my mppt to charge a 24v battery??

Hi I want to make a setup with 6 solar panels total. They will goi either in 2s3p or in 3s2p. The maximum series fuse rating for the 1 panel is 15A, my question is, if I go to the 2s3p configuration or the 3s2p what kind of fuses should I install? Thanks for any help.

Two of my 235W poly solar panels went out. I had four wired in parallel (panels each had 30V, 7.85A). Can I replace them with 330W mono panels or would mixing the two types or panels be an issue?

Like the series but..is there a sirexr link to the whole series. Like Lesson 1, 2, 3…. On different rv forums we get newbies asking about solar installation. I refer them to your YT channel but I’ve complaints that it’s hard to find the series and I’m at a loss to guide them. Maybe a Beginner Guide to Solar in the Playlist. I watched series or parallel to day. Won’t be long til my 6-100w panels will be ready to connect.

What if you have 5 100w panels? ( I now see you can probably use 150/45 mppt for seies connection) I assume you have to put them in series, so you meet the victron 5v+ battery voltage threshold to start the mppt charger. You have at that point with 5 panels in series, near the 100v limit on the 100 / 50 mppt. So - do you need to move to the 150 /50 mppt victron model? Also victron electrical engineer says to wire in series to collect morning sun or shade sun because of the 5v+ battery voltage startup rule. But other people say series will not work well if one panel is in shade. But they say the parallel wiring does not have the one panel in shade problem. Using 5 Rich Solar panels.

If I have 8- 230 watt pannels wired series parallel. I get 144 volts at 36 volts open circut, if I added 4 more pannels wired the same will it stay at 144? And with 12 pannels will I exceed the charge controller amp max.? I have a midnight 3548 hybrid.

Thank you so much, this is by far the best video about solar panels I ever watch really thank you so much, you made me finally understand it 🙏🙏🙏

Can you please help , I'm trying to put together a system to power my RV . I have 4 315 watt panels 37v and I purchased a powmr 3000 watt 60 mppt solar all one the controller I believe has a max 100v and 1400 watt 24v . will these work together. Also purchased 2 renogy 12 v 200amp hrs batteries

Hello, I have a renogy 60 amp charge controller, it supports 12, 24, 36, 42 volts. I have four 200 watt panels on my roof. Should I run them all in series to run 48 volts, or parallel series to run 2 sets of 24 volts. I have a 300ah lithium battery I'm using in my rv.

Hey I have a question I have a 335w three junction box solar panel when I test the positive and negative lead cables the volts are reading backwards I keep getting -00.1 or -00.2 any ideas as to why the volts are giving me a negative reading instead of a positive???

Question ? So far I am following along and understand the math, what is series, parallel and series/parallel. What I don't know and asking is when it comes to charging the batteries, what is more important - Volts, amps or watts? I understand it is a combination of all three. But what is the most to be concerned about? (In a camper type setup. Me, it is overlanding out of the back of my truck) Thank you. I do fine your videos very informative.

Hello there 😏 I have 2 x 115watt panels and 2 x 100watt panels I want to charge my 12v battery system. I have an mppt charge controller.. A victron 100 / 20 . I 'think' i know the contoller is not big if my array is in parrell but what about in series ( 2 x 115watts together and 2 x 100watt panels ) ? Im trying to avoid having to buy a bigger controller ! Plus series seams very sensible for someone like myself living in the middle of the uk . The aroglithms kill my head lol

Hi ;Nate I am new to solar , I bought an all in one inverter 3000W ,not understanding at the time about the VOC max input , which is 75V input on the this inverter . I have 6 -100W panel , after watching your video on wiring series and parallel put me at 60V , should I add a 75V dc circuit breaker to solar array for add safety, I live in a warm climate area with a few mouths of cooler weather, concerned about the increase with cooler weather.

I have two sets three 100W, 20V, 5 amp panels. Each set of three is wired in parallel (15a, 20V) What makes more sense wire the two sets together in series to get 40V and 15a or in parallel to get 20V and 30a ?

Hi. I have an 40Ah Epever tracer AN type charge controller, 6 12v 100w solar panels and a baterry bank of 24V. What is the best panels aray please? Kind regards.

Great info and yes very confusing. I'm trying to do a pv hot water heater system. I have 6 325w sunpower panels and a 100 amp mppt controller. I'd like to skip the batterys, wire this to a 24v element in the bottom of my tank, use a snap disc thermostat 140 degree. Assuming it will never get to 140 at the bottom of my 50gal tank. I will also leave the top element tied to the grid and set it to 125 in the event there's no sun. First it sound like I need a bigger CController. How should I wire these panels? Thanks Will

Good afternoon Nate can you or someone please help me with how to wire 29 solar panels 250/30.2/8.43 amps to a sunny boy 7.0 string inverter I got it to work with 2 string's 9 panels each in series but I want to see if I can use All of them ... Thanks

That's a beautiful video you could and explains a lot it makes sense everything you said but my question to you is which will charge faster my battery my 12-volt Bank voltage amperage or amperage
