My all electric house is in a rural area. The generator that came with the place is a 20KW Onan, The bad news is in can't handle the house. I think it is the Aux Heat on the heat pump that is the problem. I have to also power the well pump and the septic pump.
Is your house single or 3-phase?I'd be curious how much horsepower your well and septic pumps require. The most I've seen is 15hp @ 11kW, but that is pretty massive for an average home, even an off-grid one. Typical requirements would be in 0.75kW - 5kW range, which is a wide range.
Do you know how much power the heat pump requires?I'd struggle to see how a 20kW generator struggles to to run a home, unless you've also got heated floors, saunas, steam baths, water and space heaters, electric stoves and ovens all running at the same time :-).
