May as well power the plant with it on those days.
You'll also need to keep it running all day to provide the few minutes per hour of use. Expect it to be powered by a 6 cylinder diesel engine. Not quite as big as the hospital gensets. You'll be looking at a genset that is typically used to provide backup power to large commercial buildings like schools, chicken farms, dairies, and police stations. That motor will suck major amps at startup.
Note that folks using little tiny 1 HP well pumps report needing no less than a 5000 watt genset even though 1HP = 745.6999 watts.Ī single phase 10HP motor is pretty rare. That's running watts and the startup current will be the bugger. My HP calculator tells me that 10HP=7456.9987 watts.
