I have 4 6v batteries and a 2000w MSW inverter. I've used the microwave for short bursts like defrosting with no issues. It sounds like it's unhappy but the amp draw was within expectations.
I did notice that the clock runs faster on the inverter.
Ok some science.. The clock runs faster because it is MSW..
The clock runs fast not so much because the inverter output is MSW rather than pure sine wave, but rather because the frequency of the inverter output is something like 60.1 Hz rather than 60.0 Hz and the microwave clock uses the power line frequency for its time reference.
