That's only if you want to backfeed. If you just want to supply your home in an outage, it's pretty straightforward to get a permit and have a transfer switch installed.
Something tells me that it will be a while before we have EVs with built-in 240V split-phase inverters.
- bob29 6y agoHyundia announced an EV with built in inverter, they call it Vehicle To Load[1]. Like you mention with a transfer switch your whole house could be a "load" For a non-emergency it probably makes sense to use a <70% depleted 2nd life battery, and save the new battery for transportation usage.

- rootusrootus 6y agoI didn't see anything in there about inverter output, other than it's pretty modest at 3.6 kW. My guess is it will do 120V, like most(all) built-in car inverters right now. IMO, a good V2L setup needs to have split phase 240V in the US. But that would add significantly to the manufacturing cost of the car, so I won't hold my breath.
- chipsa 6y agoMost EV internal chargers are setup only for rectification. However, there's some slightly more expensive designs that would let it also act as an inverter. I believe this is what's spec'd for the Cybertruck.
