Back Up Power

So Fall and Winter are approaching. We have heavy rain and lots of snow which cause power outages.
I am looking for some type of generator and battery that can power my room when these times occur.

Here is what I have going:
1 - 400w HPS
1 - 400w MH
4 - CFL 23w (100w equivalent)
6 - 12" fans
3 - 4" exhaust fans

Any thoughts?

When I used to do a stealth cabinet grow with LEDs I used to use those batter back up systems for household electronics like computers, etc.

but with all the the stuff you're running I think you might need a gas powered genny, a small one but still gas powered. There might be other options that I dont know about though.
