I personally use a generator, bought my first one for $200 bucks used, and it could power most of the house. Then I had my business buy a much better one that could power the house and is designed to be used with electronics. Basically supplies a much cleaner power supply.
What I am getting at, is that you can look for a used gas generator and probably get it cheap, in many cases the same price as buying UPS's or battery packs. And with a generator the power is unlimited, as long as it is gassed up.
