Kill-a-Watt & 1986 Onan 4.0 BFA
Good afternoon, So the other day I plugged the KAW into a Rat Shack MSW inverter and got something like 135 volts. Of course my cheap meters were reading between 90 and 100, so I thought it should...

My coach has a BF 4.0. The output is clean and the unit is very stable. I keep a KAW and an extension cord in the case I have to tweak it (altitude).
I also have a 1Kw MSW inverter. They lie. It is not a Modified Sine Wave, it is a Modified Square Wave. I do have an O-scope and have looked. As best my expensive instruments can figure it is about 50% distortion. (This could make speech unintelligible.) Indeed, the KAW Freaks Out when I try to use it on the inverter power. I do not believe that either of mine (I have two different models) are true RMS. I say this because my Flukes that are true RMS give me different values.
