All this and little info. :(
A generator that is built for 24/7 service is referred to as PRIME POWER rated.
If rented a prime power generator will be installed, and maintained by the rentor. They take care of maintenance. This is not inexpensive.
A new home typically has 200 amp 240 service. A huge generator equivalent.
At a 20 Kw load it would not be unusual to see a 1 gal/hr fuel consumption, This would be with a 12-turn unit meaning 1,200 RPM, An 18-turn unit uses typically 12% more fuel.
Look at the starting load on a single worm-drive Skilsaw. Typically 2 Kw. Electric homes are terribly inefficient money wise. I remember at Lake Tahoe, condominiums with 3,300 kWh monthly usage. I pencilled out a preliminary design for solar power in my place in Mexico. NINETY group 27 lithium batteries, and eighty 300+ watt solar panels. For an all-electric home with Air Conditioning and dehimification for 1,700 square feet, electric clothes washing and drying, R/O system.
Fun, ain't it?
