Ah I see, mine is only a 20A breaker. Would it not simply trip the breaker? The mains cable must only be about 10 meters from the 20A breaker and another 3m to the inverter so the voltage drop should be fairly low.
I'm currently away, all that is wired is Active,Neutral,Earth &U,V,W, motor earth.
Correct me if I'm wrong but if U,V,W were wired wrong would it not just spin the wrong way?
Would something like this be better?

I know it's only 650Hz but I don't need much over 16krpm..
A friend has offered to lend me an Schnieder electric atv320 although it's only 2.2kW might be worth a try?
