Modified sine wave? How well does it run motors? I like the gfci part. That's smart thinking by the designers.
Yes, it is modified sine wave. Sorry, forgot to mention that.
This inverter powered our kitchen subpanel since last January when I bought it. The transformer in the microwave buzzes but it doesn't seem to affect the microwave's operation otherwise, other than the digital clock on it would "drift", which I think is pretty common with any modified sine inverter with digital clocks.
It also ran both our freezer and 'fridge for all that time - the AC amp draw on both is the same on inverter or genset power so they don't seem to care about the modified sine wave.
Since this inverter was mounted on the wall in the garage I also plugged into the other receptacle on it to power the garage subpanel to run my air compressor, bench grinder, drill press, hand drills and saws, and lights in the garage. It ran all that stuff fine except for the bench grinder. It would not start the bench grinder motor. That is a 3,450 rpm motor with no capacitor start on it. Interestingly, if I would turn on the drill press first, then the bench grinder would fire right up and run fine. Then I could turn off the drill press and the bench grinder would continue to run and I could use it.
I have no clue why it wouldn't start that bench grinder motor but I suspect it's because it isn't capacitor start. I also have no clue why turning on the drill press first would allow it to start and run the bench grinder. But that's the only real "problem" I ever had with it.
