Hi Nate, again I want to thank you for all the help that all your Videos you provided., I installed 840 Watts with my 4 -100 amp BBs and they work great. My class A is Almost all Electric, Samsung Fridge, Induction cooktop, Microwave, Tv, Hot Water is by Propane or Electric and force Heat is with Propane. I use approx. 30% of Bat. thru night ( Fridge and Misc) The morning I throw everything at the Array, Mr Coffee, Toaster, and Induction... check it out... I can make it through the day without running the Gen. as long as I have about 7 hours of sun.. It's working great and I am Loving it ! So again Thank you!

For car camping and hunting I cable lock a 220 watt Off Grid TREK solar "blanket" to the two crossbars on the roof of my compact SUV. Then I plug the blanket into my BLUETTI AC200 MAX. During late summer and early fall it powers a small cooler all day and charges the 2 batteries of my e-mountain bike at themed of the day. It worked very well this year for 5 days of hunting in north central Nevada. IT's also a comforting system to have for extended power outages.

I like how you do these informative videos, very clear🎯😎☕ I really need to get off my behind and get a system set up, for my watchmans trailer,( it's a crude, 8x12 box, from a fire/rescue ambulance. Kinda short, inside and plan on raising the roof later on. I need enough power to operate a small chest freezer, DVD player, flatscreen tv and a few lights,,,and AC unit, 5k btu, mounted at back wall.( necessary during summer🔥) Main thing holding me back is not being able to save enough money, the expense of running a small invertor/generator ( gasoline), is not getting any cheaper. Crazy part about it is, if I didn't need to run the generator, for freezer and AC, I could more easily save money, for the solar power set up.

@terrybrown3199 3 года назад

Using your 3, 100 watt panel setup vs a single 300 watt panel I'm curious if the only benefit to having multiple panels would be if the panel quit working? Could you limp by on 2 panels with reduced power consumption or would the system not even operate with one panel down. In my mind having the benefit of limping along on reduced power is better than putting all my watts in one solar panel?

@AlyssaGuthery 5 дней назад

I have a set of the 4, 25 watt panels and you can choose how many to plug in, so yes! 💯 I have also heard that having different styles of panels are important for low light v higher wattage per panel. The harbor freight panels are good for low light (I got the kit to start out my solar journey) and it's still working on rainy days 3 years later. The higher voltage panels are excellent for full sun to charge more efficiently!

@edgibson1202 2 года назад

Have you ever been involved with Solar on a motor yacht? We have a 50 foot one and all the lighting is 12 volt. I am installing a new refrigerator and freezer, both will run on 12/24 as well as 120 volt. If it wasn't for the 3 - 120 volt air conditioner units I think I could figure it out. The AC's draw about 25 to 30 Amp to start then about 15 to 20 for run. We live in Florida where it hot all the time and have a lot of sun. I figured one time that all the 120 except the AC would be around 1800 watts. There is a 12 v battery charger that charger 3 batteries that could be charged via a solar charger I think. That would remove that 120 volt load maybe. Looking for some ideas on this. I have room for at least 4 - panels 2 x 4.

So when trying to meet the second metric of solar panel voltage are we looking a the "open circuit voltage" rating for each panel? Then multiplying that by how ever many panels in series there are?

@EXPLORISTlife 3 года назад

Use the Maximum Power Voltage (Vmp) for that metric. The Open Circuit Voltage is really only useful for sizing the charge controller in terms of maximum voltage input from the array.

Hi, great videos! You have helped me a lot during my van build. Could you kindly help me with a question… I’m connecting two solar panels to my solar controller tomorrow and I was wondering if I can just solder them instead of using mc4 connectors? I brought two mc4 branch connectors as four wires need to connect in two from the controller. The connection is just terrible and I was very tidy on crimping them. This connection is inside van so doesn’t need to be a water tight seal but I do need a strong connection! I pain on soldering two positives to the positive and two negatives to the negative. And make sure the put plenty to heat shrink so they do not connect in the wall space. Your thoughts on this would be very grateful Many thanks Justin

@smokethirteen 2 года назад

You missed one important factor. Higher voltage between the panels and the charge controller is preferred because the wire size can be greatly reduced making it cheaper and easy for routing and high voltage give less efficiency loss.

Hi Nate, I know it's been a while but I'm hoping you would see my comment/question. You mentioned the array voltage should be at least 20V over battery bank voltage for best MPPT charge controller performance. So then in your example with the 3 x 100W panels if they are wired in parallel the V is only 20V, meaning you can only wire them in series?

@@EXPLORISTlife Thanks I take that - it is a little bit strange. Some data sheet (or marketing paper) says, it needs some 4 V above battery voltage. So a 12V battery goes to a max of 14.4V. But I found a manual of the MPPT-75-10 - and in its text it is according to your statement.

For Victron charge controllers... the 'Battery Bank Voltage + 5V' metric is the MINIMUM that is required for the charge controller to come out of sleep mode. The Battery bank charging voltage +20V is a RECOMMENDED rule of thumb.

These array calculations are confusing if for some reason you have only 3 panels and do not want to place all of them either series or parallel for example difficult shadowing issue. What would be calculation for 3 similar 12v/5A panels where two of them would be in series and one parallel between those two?

@accountingstepbystep2229 2 года назад

Do solar panels mounted an inch or so off the roof shade the van's roof so cool things off, or due to the heat of the panels, do they heat up the van. I'm about to add solar panels to my 2020 sprinter. Along with all the Victron equipment you recommend in your videos! I have a question, If I mount my solar panels about an inch off the roof of my Sprinter, will the panels cause the roof to be hotter or cooler. In other words, even though the panels will shade the roof, will the heat from the panels cause the roof to be hotter, and therefore the inside of the van hotter as well. Thank you for your super great videos. If I don't see you doing it or recommending it, I don't do it with my Sprinter.

@EXPLORISTlife 2 года назад

Great Question! I don't have any data to back this up; but I would suspect that the heat under the solar panels would be less than the sun hitting the van body directly.

First off all I love your videos. But I can't figure this one out. Why do you need 20v extra for the mppt controller to work properly? I also used your mppt controller calculator but have some questions. I have the 75/15 mppt, I was planning on installing eather the 185w (24.11Voc) victron panel or the 215w (46.01Voc). The calculator recommended the 100/15 for the 215w and the 75/15 for the 185w. 185w is not enough voltage according to the 34.5v rule and the 215 didn't get recommended the 75/15 controller although it's only 55v 15a. I have the 75/15 controller because I used the ecoflof 110w foldable solar panel but when even partly in the shade it only produces 15w. Hope someone can clear some things up

@EXPLORISTlife 29 дней назад

The +20V is for it to work OPTIMALLY. +5V is the minimum. An MPPT needs an adequate incoming voltage range to do the 'T' part of the MPPT functionality.

@jonasvanheeke4280 29 дней назад

@donaldsmith3025 2 года назад

how close in volts & amps do panels need to be effectively wired in series. ie: 1 panel at 190 watt, 19.2 volts 9.8 amps and the second panel at 110w 17.2 volts and 6.4 amps. Is it correct as 190 + 110w = 300 watt array, 19.2 + 17.2= 36.4 v but degraded by the 6.4 amps of the lesser panel. resulting 36.4v x 6.4 amps= only 232.96 watts of the 300 watt array, thus 77.6% efficiency

I was looking at panels and I found a 100w - 24.3v panel that measures 873.62 sq inches (41.8 x 20.9) for $95. I then found a 485 w - 43.3v panel that measures 3645.6 square inches (91.4 x 40) for $224. So for a little more space and almost half the price, I could have 1 panel instead of 4?

When only two or three or all four panels could be receiving sunlight, regardless of which side they on, for example, only two panels on one side can receive sunlight when one top panel slides out. Or three panels active if one side's bottom panel can't be open. Would parallel wiring be best, or parallel-serial still acceptable?Thanks!

@truthwins9044 2 года назад

So I have 2-200 watt solar pannels wired in parallel and receiving approximately 22 v with 6 amps in full sunlight max, this is the most I’ve ever seen. Does this sound right? Please and thanks.

@victorjcano Год назад

On a good day up here in Washington state a 100 W panel gives me 5 1/2 A charge current so I would think you would get at least 20 amps if you have two 200 W panels

@richbosman9058 3 года назад

How about 6x 190 watt plus 100 amp controller

@marionsutcliffe1119 Год назад

I had been planning to arrange my 2 200w panels in series, but with a slight tilt relative to each other (why is irrelevant, please don't ask)... but now I've realised that perhaps the panel with the non-optimal tilt will give less amps, and this will limit the amps coming from the more optimally tilted panel. Is this correct? If yes, I would change my plan to ensure that they are both having the same orientation.

You're going to have better results if they are pointing the same way, but I've never tested the 'how much'.

My two six volt Trojan T-125 deep cycle flooded lead acid batteries in series give me one 12v battery. Each has 240amp/hrs. of storage capacity. So, my total usable energy is half of that or 120amp/hrs. Can someone please give me an idea of how long I'll have enough power to run basic items like the water pump, open and close the awning, move the slide in and out, use my LED lights, play the radio, watch the 22" TV using my Samlex 300 watt inverter before I need to charge the battery. Thank you Is it better to wire my two 100-watt solar panels in series or in parallel? Thank you, safe travels 👍👍

So, If I am Limited to 25 V and 660 Watts and Using a 300 Ah Battery Bank. I would have to run the panels in parallel rather than Series, Correct? I am using a Renogy DCDC50 and the Manual says no more than 25V and 660 Watts. I was hoping to limit it to 3 or 4 Panels for my build. suggestions? Laughter?

If your max charge controller input voltage is 25V, yes, you are forced into wiring in parallel.

what happens when the wattage on solar arrays are more than the max charging watts on the battery bank? for ex. 4,500w in panels with a max battery charging input of 2,400w. and is it better to have more wattage in case of rain, shade storms etc?

How do you set your VOC 20V higher that the charge controller if it has a Max input VOC of 25VOC? Have a Renogy Dual input DC/DC 30A charger and want to add solar but assumed I’d have to run all the panels in parallel to keep the VOC bellow 25

The 20V higher than the battery bank voltage guideline is only for Victron charge controllers.

@EXPLORISTlife 3 года назад

A 24V battery bank charges at ~29V. So your array voltage should be at least 49V for best MPPT charge controller performance (given you are using an MPPT charge controller).

You can zip tie the solar panel array wiring to the bottom of the panels. That works quite well in most cases.

What voltage should I choose? I'm searching your channel and I'm not finding an obvious video about the subject.

@EXPLORISTlife 3 года назад

The voltage of the panels doesn't really matter as it can be altered depending on how the array is wired. More info on that: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6G3Mo_OHmQY.html

@@EXPLORISTlife That's not relevant to the question I asked. Let me clarify. How do I choose a system voltage? Should I do 24 or 48? Panel voltage is irrelevant as you know. Your panel string voltage should be well over your system voltage in any case. But what should my system voltage be? How do I decide that?

@EXPLORISTlife 3 года назад

(The following are my opinions, not codes/standards) For Systems requiring less than 3000W of Inverting power, use a 12V Battery Bank. 3000W-6000W = 24v 6000W+ = 48V

@@EXPLORISTlife Thank you, that's the sort of thing I am looking for. Another question would be how to integrate 120V shore power into a split phase 240V system. Unless there's a product that does that, all I can think of is just a really big battery charger. But that may be a bit more involved of a topic.

@CanadianTexaninLiguria 3 года назад

How can 100W panels charge "earlier" than 300W panels? 150 a/h a day is huge consumption.

@EXPLORISTlife 3 года назад

Sure! So, a 300W, 60V array (3x 100W, 20V panels wired in series) will reach it's minimum charging voltage earlier in the day than a 300W, 40V array (1x 300W, 40V panel) as it simply has more voltage potential to work with. Since it also has more voltage, the MPPT charge controller has more voltage to work with when 'sweeping' to find its maximum power point voltage to find the highest amperage output for the available sunlight. 150Ah is a bit below average for the people I help out. (Average is closer to 225Ah). But remember... this was just an example, and each person should do a power audit to see what THEY will use. I've helped build 100Ah systems and I've helped build 1800Ah systems.

@dmitryz4168 2 года назад

10 years ago I thought the same way and built my system. After my experience, upgrading and rewiring I am sure now that you are totally wrong. Mistake in your logic and math is Shadows. RV solar system is not house roof array or array of power station. Very often RV panels has shadows from something - trees, houses, other RV, own antennas and AC. Nature of panels they do not like shadows and drop all power if only about 10% covered by shadow. All other panels in series stop to work as well. Solution is to use smaller panels in parallel. It can be less efficient for MPPT and needs thicker wires but overall performance should be better in real world

Five years on the road for us and 'partial shading' was never really a problem. We were either in full sun, or full shade. This is, in my eyes, a non-issue.

What if it's a 48v system

@jasonbrown467 3 года назад

then build your arrays around at least 68 volts. four 20v panels in series would be 80 volts, plus your wires will eat less of your power due to that volts/amps ratio leaning heavily in favor of volts. for my 48 volt system, my controller will work with 160ocv, so naturally i take advantage of those higher volts, my 12v system receives 80ocv arrays,
