What size portable Generator do I need in my house during a power outage?
Most average homes of 1200 to 3000 sq. ft. can run critical items in the home by using a 5000 - 7000 watt generator. The most common items that need emergency power during a blackout would be the furnace blower motor, refrigerator, freezer, lights, TV, sump pump, and water pumps. Larger Home would require Generator Systems in the 10kW - 15kW range.

What's the difference between running and surge watts?
The running watts of a generator equals the amount of power the unit can produce continuously, while the surge wattage is the additional power that the generator can produce for short periods of time to start items in your home that require larger amounts of electricity for initial start-up than when they are running.
