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...

Practical use: I have used a Mr Coffee maker with one group 24 free standing battery (no other draws) and it made 2 pots of coffee and about half way through the 3rd the low voltage protection on the inverter kicked in.
I can't remember the wattage rating for Mr. Coffee. A heating element will stand up to a lot more abuse than a motor in a microwave.
