Q: I am looking at the 30kw unit with the gm 4cyl motor. My concern is the operating rpm of 3600, it seems a bit high for a sustained amount of time for an automobile engine.

by Ed Imsland from California on January 24, 2011

A: 3600 RPM is standard on many portable and standby generators.

If you are looking for something in a lower RPM, check out the models available that operate at 1800 RPM for lower noise and fuel consumption.

Kohler 35 Res
I selected the 30RES but I really have a 35RES model. Right after power was restored following hurricane Gustav, I looked at generator sets.

Kohler Generator
High quality product, runs the house. The only problem was, the instructions say to connect the control wires to 3 and 4 in the generator, there is a terminal block that is numbered from 1 to 16, Make sure you look at the larger white wires, they are number, don't look at the numbered terminal block. We hooked it to the 3 and 4 terminal block and blow a $327.00 control board. Something easily over looked. Other than that a very nice machine.
