I may be in the minority here, but rather than struggle with keeping a fridge going, I would simply consume all the perishables first and then switch to stored goods. This would mean powdered/condensed milk which rarely tastes like fresh unless mixed in cocoa, etc. Such are the sacrifices demanded in emergencies....

I simply don't like messing with gennies. One of the nice things about working at Channel Islands National park is that for years the island developments have been powered by solar and wind. Walk into a station and flip the switch; dust off the solar panel once in a while and enjoy the peace and tranquility...priceless!
