I finally got it drawn up. Here is the PV ground mount the way I plan to set it up 2@6s2p and 1@3s2p. The only way I can think to get AC to the GW "AC in" is to add 2 new panels. One to be a new main 200A panel and the other to be a solar production panel only and change my original main house panel with almost all the house circuits in it to a Sub Panel with a generator Interlock kit to prevent Grid and PV power in the same box at the same time. It would also allow me to switch back to grid only easily if needed. This seems to be the only way that I can use solar 1st then batteries 2nd then have the grid pair AC with the Inverter AC if the PV or battery can't handle the load. If the grid goes down, I would use PV then Battery then the natural gas generator as a last resort. Please look at my drawings and let me know if anything is done wrong. I do realize I don't show sharing or paralleling the inverters and the wiring is basically what is connected to what and doesn't show L1, L2 or N connections. N and grounds are bonded in the Transfer switch per my electrician, the 1st box after the meter. Please comment positive or negative. I'm ready to purchase all this, but need to know if it will work. "Signature Solar DIY" just said they are just a parts dealer(Noting the DIY in their name) and I need to DIY. I was hoping for a little more considering this is an $18,000.00 purchase from them. I would appreciate any help anyone could give.
