Sharp eye Mister Sandals! That pic I sent is a little outdated. You were totally right about the voltage being too low with panels in parallel. I wired 2 in series and now it’s charging/working fine. If I understand you correctly though you’re saying that I’m over stressing the wiring?

25?! That’s crazy ? Any recommendations on the best BMS?

Gotcha. Would you mind sending a link for an easy to install BMS? I’ve seen a few that seem to be a pain to implement (or else are VERY expensive) Thanks

No BMS - if I can regulate the min/max voltages and battery temperature from the SC and Inverter, is it needed? RE batteries: I hope not ??‍♂️ They are Li-ion Tesla modules

ok here’s where I’m at; I’ve got the batteries charging from the panels through the charge controller. Seems to be working fine. Today I’m going to hook them up to the inverter and maybe the battery protect (Although I’m wondering if that’s even needed if my inverter has a shut off when...

UPDATE! Bit the bullet on rigid. I just got off the phone with SanTan and they are going to expedite 3 T400H Tesla Panels to me. So now I know exactly what I'm working with as far as panels go. If I need to get a different SCC or Inverter I'll do it. I still need to get the BMS as well...

What exactly is wrong with mine? Do you have a link for what you feel would be a better overall value?

I put links to all my equipment in the first post, including the SCC. Does that or anything else look insufficient assuming I find a decent solar panel replacement?

Yeah biggest concern is weight. I’ve already initiated the return on these panels I have. Looking at some locally to replace them. I agree with what you said about maximizing space, just a game of finding panels with dimensions that will fit my space right. I’m considering these 400w Tesla...

Thanks JK14. Would it be worth testing these panels and trying to figure out the “average” volts/amps or is that too risky and I should buy some like in the last Amazon link I sent?

Reno

https://www.orionbms.com/manuals/pdf/tesla_modules.pdf Last page is where I read it

Ideally Reno, but I can travel to get the panels if needed. (Just cost-benefit of paying a little more to have them local or shipped to me)

I’m in the Reno, NV area. Any recommendations on an easy-to-implement BMS for these modules?? Thank you all!!

HRTKD I already own the two Tesla modules, no return on those…I read that running them in parallel is a lot more complex than in series, hence my call for 48v…

MisterSandals I’m currently in the Reno area to assemble the trailer. Will be deploying in in the Tracy CA area. 6x12 roof area with a little wiggle room on either end..no fixtures. HRTKD I’ll look locally for rigid but I need to find some lightweight ones.. Ampster I want a BMS and any sort...

You guys have indicated that it's best to return my panels and get something else. Maybe these ones?? Seems like a reputable brand and I could get 6 of them on my trailer for a 1200W system. Looking at Ecoworthy and Renogy flex panels as well..

The batteries have the OEM BMS board on them but I have no idea what I need to do to make it work. Ideally I could find something plug and play with a digital interface haha As far as charging the car level 2, I really just want to filter extra power in the batteries at the end of the day into...

Yeah HRTKD that's what I was trying to say haha 6s3p Good advice on the fuses between panels I didn't know about that (y) Hedges thanks for your input. I'd like to be able to level 2 charge my car but maybe this isn't the right inverter? I know when I plug my car into a 120v outlet it charges...

Thank you for your reply! I spent a lot of time agonizing over the right panels to buy. I know these ones are "cheap" but I figured I could get what I can out of them and be happy with it and if for some reason it performed WAY under expectations I could return them and buy a name brand. I've...

Hi guys, My name is Colton and I just created this account. I'm a total noob when it comes to setting up my own solar/battery storage system but I'm eager to learn and have been reading/watching videos like crazy over the last little bit to try to get up to speed. I have an enclosed cargo...
