Hi, I am new to solar system DIY and am trying to install an EG4 3000 EHV-48 inverter to 2 EG4 Lifepower4 Rack mounted 48V 100 Ah batteries. I have them connected to 4 solar panels in series producing 120-160vdc. The system works to power a heat gun with the AC 120v power, but when I check the outlet with a plug in fault detector it gives an open ground fault. The fault goes away if I plug 120vAC from the house to the inverter. I intend to use this to recharge my 2020 Ford Fusion plug in Hybrid. It takes 9kw to get to work and back and I have 10kw of batteries. When I plug the charger cord in I get a fault light. I have contacted signature solar and they are supposed to be having a level 2 tech contact me, but it has been over a week and no joy. I have attached a hand drawn wiring diagram. There will be more circuits eventually, but I want to get the desired result before I expand the system. Any help will be appreciated.
