Backup power - what you got?

[corpusse]

7500 watt generator. It powers the tank entirely including lighting + fridge and freezer. One thing I did not realize after living my whole life in Mississauga where there never were long power failures is generators eat gas like crazy. Sure I can power everything but a full tank only lasts about 11-12hrs. I keep an extra 5 gallons around so I can always go 24hrs without leaving the house.

I was just reading about someone in Puerto Rico keeping their tank on a generator / solar panels for 40 days. If that happened here I'd probably run out of gas money before I lost the will to refill the generator twice a day.
