There should be no issues. My rule of thumb is very hard starting 15 horsepower three phase motor will start and run with a quality 30 kilowatt three-phase generator. That's across the line starting with massive current. You can program your VFD such that there is no massive surge and so a 10 horsepower on a 30 kilowatt will be absolutely no problem.
