The new "inverter microwaves" use pulse-width-modulation to keep more-or-less steady heat instead of the magnetron going on for a git, going off for a bit, etc. From all the test reports I've read - it makes a big difference in the quality of heating and defrosting. Much more even and steady. But that aspect does not interest me. My interest is getting a microwave that is more "linear", so to speak. I.e., turn it down to 1/2 power and it actually only draws 1/2 power from the AC source. A conventional microwave draws full power at any power setting. Just does it "on and off" for different time intervals.
I just ordered one from Panasonic. I'm anxious to see if it actually makes a difference in amp draw when using on lower heat.
Conventional microwaves have a tough time running from inverters due to DC input voltage problems. A conventional 12 volt inverter will run most equipment with an input of 10.5- 16 volts. But - when hooked to a microwave- once the input drops below 13.5 volts the oven works poorly. Needless to say when running off a battery bank - voltage will always be below 13 volts unless something is charging the battery bank while being used.
