No we can run the entire house on it except for the oven and washer/dryer. We are very happy with it and if you don't need to run the oven and washer/dryer it should work just fine for you. We can run lights, heater, TV, coffee pot, computers and microwave. We had it hooked up to the house power so when the lights go out we just swich over to the generator power and love it.
240v is to 220v as 110v is 20 120v.... Appliance's rated for 120v run at 110v. some lighting runs at 270v and a 240v appliance would be overload but on a 220 circuit would only be slightly under power.........the 240v is the limit not the ABSOLUTE it could run at 210v
