My original microwave (circa 1999) would sometimes start and then stop cooking on inverter power. I replaced it with a Panasonic. This one is reliable on inverter power but makes a lot more noise.
I conducted experiments heating water on shore power and microwave power. As I recall, with the Panasonic, one minute on microwave power raised a cup of water from 75 degrees or so to 130 degrees while shore power raised it to about 145 degrees.
I thought about returning the Panasonic and trying something else because of the noise but my wife said it didn't bother her so I kept it. It's either 800 watts or 900 watts (don't remember) and slight ly larger inside than the one it replaced but fit in the same location.
It doesn't have an "always on" clock which is a good feature when you will be turning the power off on a regular basis.
