Back to the original thread subject.....
I needed a generator to run some water wells around here if/when the electricity went out, so I had long discussions with a generator designer to decide what I needed.  I wanted a generator to run the pumps, but also, as long as I was at it, have a generator I could plug into the house.  Finally settled on a small, four-cylinder Lombardini diesel and hung a 30 KW generator end on it.  Way more generator capacity than the motor could produce, but big enough to start the various motors around which had high Locked Rotor Amp starting loads.  It puts out around 11.5 KW.  Wet stacking was discussed, and, according to the engine manufacturer, if run for long periods, the engine would need about a minimum 30% load to keep it from happening.  So, I wired the thing up for both 240 and 120 volts, and carry around two of those 1500-watt resistance heaters.  That's a total of 3KW if I need it.  If I'm concerned about the load or lack thereof, I simply plug in one or two of those heaters.  It doesn't increase the fuel burn very much at all, and keeps the engine happy.  It will also start two central AC compressor units.  ;D

If you have a compressor or electric motor with a high inrush amperage, buy one of these and install on compressor or motor - Unlike a hard start which will reduce start duration but not appreciable reduce the LRA, these Hyper Soft starts reduce Inrush amps by at least 60% - i.e. a compressor with a LRA of 100 amps will be reduced to an inrush of 40 AMPS or less.

We are selling a lot of them for just this reason, the ability to use a much smaller genet than would other wise be required to handle these loads which often represent the single largest requirement when you size a standby generator.

Also helpful if your lights dim when your well pump or compressor kicks on - solves that problem as well.
