Hello,
Im in Riverside County, CA and in the process of building a 3600sq.ft home. I just received the tentative bill from so-cal Edison and they want $28k to pull wire (assuming I share the pole tap). That's not including all the trenching, pull boxes, and conduit that I would have to install. Im not looking for sympathy, rather, an off grid solution to bypass edison. Since the cost is so high and the distance to the pole is so far (1200ft), the county will review/ consider an off grid install.
Equipment: I have a 400a, solar ready panel and im looking to install the following -- 2x EG4 18k Inverters; 20x 450W panels (another 20x to follow later); 6x Eg4-LL bats (another 6x batts to follow later); and a 20kw Kohler backup gen. The problem im having is it seems that almost every discussion and video pertains to grid-tied solutions or older inverter systems that don't have all the integrated functionality of the new EG4 18k so it is difficult to assess what is needed (i.e., will the PV breaker on the inverter suffice for a kill switch or will county code make me put an external one as well)...do I tie the gen into one inverter or terminal block into both...
To my question: what is the best way to connect the 2x inverters, 20x panels (2 strings of 10), single battery bank (6x batts), and back up gen to the solar ready 400a panel? Please don't say "connect the inverters to the panel" and "connect the battery bank to the inverter"...The biggest problem that im having is that no one actually shows how systems are wired together AND into the breaker panel.
PS: im not an electrician but semi-intelligent and able to size the system and make the appropriate calculations. Please excuse my ignorance as im trying to learn without making a catastrophic mistake.
