Power Factor is a electrical method of equating efficency in an inductive load. Unity power factor is 1. this loosely equates to no losses in the system at .85PF we do have losses in the copper and iron.

Loads also have a power factor that effects output for example a incandecent globe is a pure resistive load and will have unity power factor. A fluro is an inductive load and will have a lagging power factor. A capacitive load will have a leading power factor.

Bob I think your gen set probally should turm at 3000RPM, a 300 RPM unit would have a 22 pole gensetand be turned by a diesel ships engine.
