That's a silly function that's you'd likely never use. Takes so much power to run a house especially hvac it would be completely impractical. Buy a cheap generator for the rare occasion you'll need it for that.
Limiting energy out to 10-15 kw-hr per day, the The car battery could power most homes for a day or two.
The real benefit is in using the car battery to arbitrage electricity. Charging from a solar bank (or grid) when surplus energy is available and selling back to the grid when supplies are tight. Admittedly not all utilities currently offer opportunities to do this , but in the future more will.

Or...if a power outage is localized one could use V2H and then leave at a good time and go to a fast charger and reload. Whether V2H is a better choice than doing nothing, doing something (like V2L for refrigerator, etc.) or putting in a generator system is a different question.
