Generators sound great until you have to feed the monster.
How much fuel can you keep on hand and how hard will it be to find after a hurricane? That was the biggest complaint I heard after Charlie.
I am also not sure where you got the "72 deep cycle batteries" from. A decent battery will store one KWH so 800w should be less than 10 in the summer. I got into a lot of this when I was looking at electric cars. My thinking is one set of batteries might actually do both. Use them in a car day to day and also use them to back up your house power in emergencies. My current plan is basically the same deal except I have that 12v alternator/engine deal I made and a golf cart I have in the garage.
I am really just trying to avoid one more engine that won't start when I need it
