Boat versus RV Generator
Just curious of why our Onan generators in our boat and RV are designed to operate differently. In the 2006 boat (11KW) it operates at a constant RPM regardless of load but in the 2018 RV (8KW) it ru...

Way more efficient by the way.. For any given trip it will suck less than half the fuel your Motor home's generator will.
Depends on the loading.
- Under light load, Inverter-Generators are more efficient as they can throttle back and use less fuel.
- Under heavy load, the losses converting DC to AC make them a little less efficient.
So if you are maxing out a small generator running the air/con on a hot day where the air/con never cycles, you will probably use slightly more fuel due the conversion losses.
On the other hand, if the air/con is only running 25% of the time, you will probably save fuel as 75% of the time the generator is throttled way back to idle speed.
