This is not as "nice" and integrated as V2H but it definitely works (I tested and used it myself):viewtopic.php?f=12&t=25623&p=536383&hilit=Power+inverter#p536383
I calculated even with only 14 kWh available in my old leaf, that if it was just to power the fridge, tv, some small appliances, it would last for at least several days.
But if you want to power the ENTIRE home including A/C etc, then yes even 60 kWh would last barely 2 days.
