Microwave on PSW vs MSW Inverter- Results
I have been using a MSW inverter to run the microwave for several years now, and decided to try a PSW inverter. I expected the microwave to run a little better and for the inverter to draw more amps from the battery. But how much?
The microwave is a 2001 Kenmore (LG) output 1100w, input label says 1510w, so expecting about 150 amps draw using the times 10 rule. Battery bank is 450AH of deep cycle AGMs and appropriate wiring. The MSW inverter has worked just fine with that running this microwave.
I did a straight swap with the same wiring.
So the results are:
MSW- 123 amps, PSW- 162 amps (so it must want more than that 1510w)
Cooking power difference at full power doing a cup of cold water for two minutes, then check temp of water.
MSW- 150 degrees F, PSW- 175 degrees F
New inverter is this one:

(In the ad, Inverters-R-US can't spell "complement" for some reason :( )
The MSW I have been using is this one (except it was on sale for $200)
