On power factor correction one would have to do some research as to the generator's ability to compensate for loads that were leaning inductive (ELI) or Capacitive (....the ICE man), starting surges and all that. Going to assume the problem would be handling big inductive loads. One would think the heat pumps are capacitively compensated to run in the 0.85 PF arena which is the limit for my COOP. I don't know where inrush surges fit in, aka are they limited to 0.85 too or is there an exception and if so what it is.
On single phase are you talking about a 240V swinging Wye where the 3rd phase is magically produced from the single phase power line? We had a community water well installed and no 3 phase was available. The pumps required 3 phase and the power company put in such a contraption since at the time we couldn't afford to pay the $50k required to bring in the 3rd line. Not familiar with any of the specifics, just know the overview. On our high HP well pumps, it was a nightmare. I am not aware of the design of the pumps as to how they looked to the power co.....L-R-C. But after about 6 months of putting up with it, we magically found the money (side note at a bank) and got it installed. End of problem.
On what you get for what they specify, one would surely have to look at the equipment specs to see the conditions for the rating. 17-18kVA out of a 30 kVA unit sounds kinda low to me.
Best I can do as my pedigree was not industrial power and it's application.

Today's Featured Article - A Lifetime of Farm Machinery - by Joe Michaels. I am a mechanical engineer by profession, specializing in powerplant work. I worked as a machinist and engine erector, with time spent overseas. I have always had a love for machinery, and an appreciation for farming and farm machinery.
