12v inverter draw on batteries with microwave
If I get a 2000w inverter for my MH and use my 1100w microwave, what will be the draw off the house batteries? Using Ohm's Law I calculate about 9 amps draw at 120v. Then converting from 120v to 12...

I calculate about 100amp draw. That's per hour, right?

if I run the microwave for about 15 minutes, I am using about 25amp hours.
