I see. A single Powerwall cannot coexist with that much PV; you'll have to either isolate the Powerwall from the PV in a partial backup and let the PV shut down in an outage or use contactors or something to disconnect all but (again IIRC) 7.6kW AC of the PV so it can run off grid with a single Powerwall. You would need three Powerwalls for it all to run off grid.Okay. Yes, it is a baseline quote without rework or upgrades included. We are adding it to the customer's existing array of 21.56kW, Fronius inverter at ground mount.
