I looked into them about a year ago...and if I remember right even the really expensive ones could only run 1000 watts for about 20 minutes.

A backup generator would be the best way to go, but as someone mentioned on here, the lower end ones kick out really dirty power. Some thermostats will just give you an error. Either a better generator, or just running a room heater would be probably solve the problem.
