Hi ,
I’m installing a ground mount solar system with multiple strings. I’m running DC from the multiple strings a long distance to the house where I will put the inverters. I have a few grounding questions and I haven’t been able to get exact answers with a lot of reading:
1. I think I can combine the bare copper grounding wire from my racking and panels into one bare copper wire that will run the distance in my PVC conduit with the DC wires and connect to the two inverters. Is that OK to do? Note that I have a grounding rod buried at the arrays and will also connect to this.
2. I have a bunch of excess bare copper wire. Can I use this for my AC output that will tie into my main house panel, or does it need to be insulated ground wire? I’m using flexible aluminum conduit between the inverters and the main house panel.
thanks
Steve
