The sine wave actually looks quite good no hint of saturation, clipping or wave deformity. Only a single trace, rather than a twisted rope. I suspect that when placed under a load much of the "broken" curve will smooth out. I would also suspect that yet another layer of fine grained noise will disappear from the PP2000 when it gets a taste of this sine wave.

Bud, yes you are right, this is a no-load wave.  You might be also right in your prediction that after I load the generator then the curve might smooth out. I took a lot of work to start the beast and expected more gratifying result. The conversion with automation and excitement circuits to single phase, dealing with 20A currents and 60A start up currents – all of it a pain in ass. I did not put any load in the game as I would like to put a runtime capacitance between the A and C line as now my generator get 3 phase only during start up and as soon the motor get cruse speed a relay shuts down the C line. During the run the motor run from 2 phases and it is losing 1/3 of power, I need to put a run time cap to fake the 3rd phase and to get more efficiency power from it. So, to use the motor-generator option is not a plug and play situation. Now, where can I find chip 250V paper and oil non-polarized caps of a few hundreds mfd I do not know. In the past I was trashing them as they had no use for me but now I need to buy them.
