It's going to be better if you have a PSW inverter though and some are getting pretty cheap these days.
Seems strange economics to save a few bucks on an inverter and put who-knows-what at risk. But that's just me.
There is no proof that MSW does any harm to a compressor motor, only those that say it could, may, possibly, or some other form of conjecture.
This is our 14th year with a residential using MSW, and the second MH with the same set up. Previous coach was sold four years ago and the new owners are still using the same 14 year old Amana.
Seems to me it would be poor economics to purchase an inverter when one already exists.
It is not conjecture but fact that MSW inverters cause motors to draw more current, start harder, and have a shortened lifespan. There is much research on line posted by testing labs for "off the grid" equipment.
Remember that all MSW inverters are not created equally. Some have more "steps" to smooth out the square wave than others and those will not be as bad as the ones with fewer steps.
I would like to read some of the test results you refer to, but have not been able to locate any. Everything I find says refrigerator compressors suffer little or no adverse affects from MSW inverters.
