Great RotoVerter
Mart,
Good work getting your RotoVerter up and operational! I HIGHLY RECOMMEND that you purchase a "Kill-A-Watt" meter to further your experiments. This meter will allow you to measure the voltage, current, watts, power factor, and volt-amperes reactive going into your RotoVerter. For $35, its an excellent investment. It will increase the total amount of information you have about the running characteristics of your RotoVerter by a factor of 10.
The reason you can't run the RotoVerter from your inverter and batteries is that you cannot overcome the huge "start surge" required to get the motor up to speed. This overloads your inverter. You might need a 1500 Watt inverter to START the motor, even though it is RUNNING on about 230 Watts, once it gets up to speed.
If you have seen my DVD Electric Motor Secrets, I show how to build a Dynamometer and run a mechanical work production test. If you want to really KNOW the efficiency of your RotoVerter, I suggest you build a dynamometer and run a Dyno test while measuring the inputs with the Kill-A-Watt meter. That will tell you the WHOLE TRUTH about the efficiency of your RotoVerter.
Keep up the Great Work!!!
Peter

the spring scales needed to test this would be like out of the struts of my car 
he he
There are experiments we have done which are based on more then just PF
