Thank you! That is very solid advice and I appreciate it. You are right that the bms was in LVD mode and we put 4 12v batteries in series to get 48v and "jump started" the battery bank, then turned on the inverters successfully, and when the charge light came on, we removed the connection to the...

We ordered this kit that comes with 2 inverters and 4 batteries. https://sungoldpower.com/collections/off-grid-solar-kit/products/off-grid-solar-kit-13000w-48vdc-120vac-240v-20-48kwh-powerwall-lithium-battery-12-x-370-watts-solar-panels-sgm-1320m I have read the manual but can't find details...

This is my first system so please go easy on me. My Dad ordered the SGR-13KM Solar Kit from SunGoldPower.com with 14 solar panels and my cousin suggested we hook up the panels in a way that will give us the best of both worlds, high voltage and high amperage. The more I think about the way he...

The system ran fine but now we are getting a BP error. It was running on battery at night and around 5:00am, the whole system cut off. Now the voltage on the batteries when testing with a multimeter is around 3V. We then proceeded to hook up the generator to the inverters but it's not recharging...

Yea I mostly understand series vs parallel and how the volts and amps add up. I think you answered my question with saying that all parallel strings must be the same voltage. The 3 possible ways of hooking up 14 panels that you explained lines up with the logic and research I've done. Noone is...

good observation. Using splitters. Each custom made cable would have a splitter on one end. With it all hooked up, you only end up with the Positive from p1 and the negative from p14 needing a 100ft wire going to the inverters (in my cousins model). Max PV Mppt Operation Voltage = 90-390VDC...

I do or I wouldn't have posted this question? but it's not that simple. The short answer is that I'm the guy that has 20 years of experience with technology (but none setting up solar systems) and I should have all the answers.

Yea sorry I thought it would be better than my chicken scratch on a piece of paper, but i give in. I have even more questions now that I see it on paper. Would your advice change knowing that It's going to 2 inverters? Wouldn't the 7s2p configuration have an amperage of only 26.26 and the...

Thank you for confirming what Hedges said. Yea I think I just did things out of order. I started in the manual and none of it made sense. Then my cousin gave his recommendation, then I researched, and now I posted. I should have went back to the manual but not sure that it would have totally...
