Montreal is about to be hit by a bad ice storm -- 2-3 cm of ice on everything forecasted. I hope they got it wrong, but if not, I may lose power for a few days.

May be time to invest into an ecoflow home battery and a vehicle that can do v2h.
@monsieuricon in theory any vehicle can do v2h, if you use its 12v system to trickle charge a home backup battery. check out https://www.evextend.com/ . I have the inverter kit but haven't gone for the backup system yet
