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 :-).
