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 ...

MSW
The first inverter I encountered was a Tripp Lite 550. That was 38 years ago. Then Trace introduced it's "improved" modified sine wave which supposedly was a great improvement. 2-steps to the top of the still square-top waveform.
And then...
"Someone (I cannot remember whom)" supposedly introduced an inverter with 1-2-3rd step waveform. My 1995 Trace 4024 still wrinkles the waveform and the 2013 Samlex is good enough for whom it is for.
What I do not know is if the pure sign wave inverters will follow suit with the MSW units and revert to a pure square wave if a low input voltage threshold is breached. Rubbing elbows with Brontosaurs, ancient Trace inverters supposedly had the lowest spec square wave voltage threshold. The Samlex however seems impressively heavy (heatsinks and transformer) for it's output spec.
