I did take some footage of the readings. My pop stopped over with his oscilloscope and we probed the generator and power inverter.
Depressed depressed...
Both the genset and the powervertor were square. The powervertor had crazy anomalies at zero crossing. The generator was fairly clean, but also a square wave. From what I have read, pure sine wave power inverters are the way to go, so I am now looking.
I am open to suggestions for true-sine power inverters if you can recommend one.
Here is a picture of the generator's -120 volt square wave. <<- (square wave?
that just sounds wrong
) You can see a little spike in voltage at the beginning and end of the cycle. It was very small, we were zoomed in pretty far.
Next is a video of the +120v portion of the cycle:

Here is a video of the power inverter probe. I thought we were doing something wrong:

Sorry, but I tried to resample them to mpegs, but windows movie maker just kept crashing, so I couldn't edit them and bring the size down. I don't think avi videos stream, you'll have to wait for the whole video to download before it will play.
Enjoy, and hit me with some power inverter suggestions if you have any.
ciao !!
