I can tell you 1200 watts is not even enough, even though most refrig today do not use more than 500 to 800 watts, it is not the continuous usage you have to worry about it is the power on surge that you will have problems with. When a refrig turns on the compressor it exceeds the 1200 watt rating of the generator for a short period of time so it trips the breaker. Most generators can not handle motors inductive current draw so they trip off if you do not have a big enough generator.

Also if you go to a large one, most have a 10 or 15 amp breaker on the 110V out lines so they could trip when you have too many things being powered off them and the motor turns on. Very few have separated circuits for each 110V outlet, some have 220v and 110V outlets.

With that said if you not looking at 3000 watt or greater it will not support a refrig and other things in your house.

I have a 4000 watt generation with 220V out as well as 4 110v outlets. To make it easy I have wired it into my house main on the 220V side, but this requires disconnecting the house from the main power, not something I do not recommend unless you have a clue what you are doing.
