I have a 7500 watt briggs. I can run the whole house basically fridge, furnace, television, as many lights as needed, the computers, and 6 Rena canister filters,9 Aquaclear hob
's, and the blower in my fish room that supplies about 70 tanks!! My next move is a 14,000 automatic start permanent generator so I can run the AC
unit for our house.
