No. A 10hp phase perfect will run a 10hp motor. A 20hp a 20hp motor, etc. There is plenty of info on their website, and they speak in terms you can understand if you call. A great product.
A good setup for a 1 man is to go with the 10hp PP, then run your diust collector off a separate inverter that is single phase in, 3 phase out. If you have machines over 10 hp like a wide belt, you'll need to go larger of course.
