Honestly, I don’t see the value of this. I don’t want my EV battery supplementing the power grid or supplying power to the house. I wouldn’t want to have a dead car in the morning if the power went out and it’s trying to power the house. Installation cost is another factor. You will need an ATS to isolate your house from the grid, you can backfeed power. It’s a safety issue. At this point if your are worried about the power going out, buy a generator. I think we would need like 12 Powerwalls to power our house during the summer for 1 day. Air conditioning sucks the power up. A standby generator is $10k, it’s a lot cheaper.
