...the generator 220v is incompatible with "household" 220v.
This is due to the phasing difference.
Household 220v is at 120 degree phase shift. Generator 220v is at 180 degree phase shift.
Resistance appliances, like a water heater, will probably work ok.
However, a 220v electric motor that is phase sensitive (e.g. capacitor start) can have trouble.
Easiest solution is DO NOT run 220v anything with it.
Only use 120v unless you are willing to ensure phase shift compatability.
Of course, the above is somewhat academic if you are only running 120v.

A normal single phase residential service is 180 degree, at least around here, just like the generators. Industrial three phase delta or Y are 120 out of phase, but at least in my corner of the US, most homes have a single phase service using a 240V center-tapped transformer. That makes 180 degrees.
My Champion runs my 240v air compressor and 1 HP 240v well pumps without problems. Both are single phase 240V motors with capacitor start.
