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...

we use the MW 90% of our cooking
upgrade the alternator to a high performance version that puts out more amps than the standard version and does this at lower RPM's
solar..is nice..but it only supplies power during the day
it does NOTHING to help at night when you want to warm something up
but there is a big difference in ONE minute to warm a cup of coffee
or the Two minutes needed to heat a cup to make hot tea or soup
and 15minutes to cook something
with good batteries and wiring "warming' something at night is NOT a problem
baking a potato is another matter
Depending on the size of the potato! :B
We use our MW a lot. Using it with the inverter we'll only run it for a couple of minutes, maybe up to five which is enough for a vegies for the 2 of us. We then let the battery voltage recover (several minutes) before the next lot. Our 484 AH of batteries are producing 160 Amps or more--the longer it runs the more amps it draws as voltage drops.
Anything more than that its gen time. It usually needs the exercise anyway.
