Thank you

I’m looking for more of a RV off grid AC panel or a combo AC/DC panel for my off grid RV Semi trailer. House panels from Home Depot run about 5 inches deep. I hoping to find in a 2 x 3 framed wall. Will have 220 breakers for charging electric car and dryer. So I was looking for a 200amp panel...

Thank you for all that information. Very informative.

I’m building a tiny house from a refridge semi trailer. Getting ready for plumbing/electrical. I got a great deal on 22 used solar panels total of 6500 watts. But some 350, most 300, and some 250. I also will have shade issues. I’m interested in micro inverters but mostly see them in set ups...

Anyone know where to get a 12v 200a BMS for lithium

So looks into these. I see TS4 A F. And some TS4 R F. Another thing to figure out. What’s life of these? I Found some open box R F

Definitely expect to take a bit to charge the 48 volt battery bank. Probably looking to add a panel or two message depending on my roof space. I’ll look into your suggestions. Thank you

recently I needed more amp hours in my van. I had three of the 12v valence batteries. My system has the 12v 3000 watt pure sign inverter, 4 100w solar panels, a 50am Renogy DC to DC with MPPT. This system worked fine but I run the inverter 100% for a small energy efficient AC fridge, and my...

I have 16 of the LifePo4 100amp 3.2 volt cells hooked up to give me 400 amp hours at 12volts. I use the 120a 12v 4s BMS from overkill. I also have a 3000 pure with 6000 surge inverter. Everything works well until 1. I start pulling around 1500-1600 watts. The BMS shuts batteries off. 2. If I go...

6500 watts to start.

I got my Van battery bank going pretty good. I have eight PO4 100amp hour batteries, two in series and than the four banks parallel. Hooked up my 4 bank BMS with phone app. It works good. I am thinking it should say 800AH but it says 100AH? I am thinking off adding another eight batteries as I...

So this may seem really obvious, I see that on the BMS app I can go in and change the AH from 100 to 200. Would that make the batteries last twice as long. I was thinking the batteries where at 25% because of the app, not because they stopped working. Or to double the batteries life (AH). Do I...

Going to be installing my huge semi off grid solar panel soon. I am definitely going to be dealing with shading issues. I all ready have two EG4 6500 inverter chargers. So I feel using micro inverter would leave the Pv inputs empty. So possibly I’d be using the optimizers. Just started seeing...

Yes, I have two circuit fuse breakers. One between alternator and system and one between systems Snd inverter

Would I need two new 12 volt BMS’s? I was think splitting the bank in have and parallel the two twelve banks. I just wasn’t sure about the BMS

My 12v 3000w inverter went out. I decided to upgrade to two EG4 LL 48v 100ah batteries with the EG4 3000 charge Inverter and plan on charging my Leaf from it. (That’s why I went so big). A few issues I’m having and any suggestions greatly appreciated. The charge inverter requires 45v to...

I am interested in mounting these underneath a semi trailer I’m converting to an RV. Want to put them either flat in a large ventilated compartment. Asked signature Solar if this would be okay. Answer was follow installation instructions in manual. Manual says on a non combustible wall, and...

Solar panels going on semi trailer. And definitely going to have shade issues. Definitely seem like the optimizers would be a great help for shade. Do I need a combiner box as well?

Thanks for all this great information. Definitely explains why I couldn’t find many talking about micro inverters for off grid systems. Looks like I’ll need isolators. I’m stuck with location and we love the trees.

Thanks, The semi is going to be a RV basically I’m converting it. The layout I’m still working on, but wanted to figure out this optimizer and combiner box thing. I check out that thread thanks.

I have the two EG4 6500 and the big 300lbs 48 volt battery. 285 amp hours. Might up grade to two of those if needed.
