I just finished installing a (New) Yanmar L70 (7hp) on my portable 5kw generator which originally was equipped with a Yanmar L90 (9hp) diesel.
My question pertains to the fixed losses required to turn the generator at rated speed and energize the field.
Other than the increased power required to turn the larger cooling fan does anyone know the difference in power output of a 5kw versus 10kw generator head using the same input HP?
Advantages/Disadvantages of oversizing the generator head?
