Thanks everyone but it sounds like a bunch of "educated guesses".
Isn't there some precise math?
Sure
2 is weak and marginal at best for a 2000 watt inverter. Minimum recommended by Xantrex is 400 amp hours.
3 don't go there.
4 is about minimum and should work fine. They work fine for me. 15 full minutes will still be a heavy discharge especially in one swoop. My MW draws about 1650 watts and 150 to 170 amps from the battery. So the 1000 should be easier. But is that cooking power or input power?
6 if space and money are easy this is the way to go.
