[TowerTalk] Kohler home generator hash?

[Tim Duffy]

Hello Kim:

Excellent post about soft start on your air conditioners. That is important
on generators and also for the AC mains as well. All six  (we use two 3 ton
units for shack cooling) air conditioner units here at K3LR have soft starts
and there is no drag on the AC power when they come on line.

I learned about soft start air conditioners early on when constructing
cellular networks. Without soft start the generator voltage drop would cause
significant issue for the sensitive network equipment.

FWIW, we have a small General 14 kW NG air-cooled generator with a manual
transfer switch. It's RF quiet at any frequency I can hear, from the BC band
through 450 MHz. 

As an aside, we had trouble starting our air conditioner units with it (4
ton and a 2 1/2 ton units). The start current requirements were well beyond
what it could reliably handle. But, last summer I installed some true
soft-start modules (made in Australia). The difference was staggering: I can
now start both units simultaneously without problem on generator power and
lights no longer dim when the units start on commercial power.
