Gweiloman Posted September 22, 2022 Share Posted September 22, 2022 Does anyone know what sort of electrical work is required in hooking up an EV battery to the house mains as a backup battery? I already have a 3Kwh solar install. Link to comment Share on other sites More sharing options...

I already have a 3Kwh solar install. The first thing you need is V to L capability built into EV. If it’s just an EV battery then you need cooling for the battery plus all the circuitry for charging. Actually installing a battery backup is reasonably simple. 1 Link to comment Share on other sites More sharing options...
