We have a 26 kW natural gas generator for our home. We’ve lost power for as long as 8 days and need power to the grinder pump to be able to use the bathrooms, and one large enough to kick that over will power the entire house indefinitely. It’s getting old and unreliable and we’re going to replace it. Can the Tesla home charger can be powered by a generator? My Tesla home charger is an 06/2020 purchase.
