How To Select A Home Standby Generator

With residential standby power systems, there are a variety of output sizes from 12 kW and higher. The best match will depend on the power (wattage) requirements of your home and the available fuel types. Some appliances with electric motors (refrigeration, air conditioners), require up to 2 to 3 times the listed wattage. The generator should be 20% larger than calculated requirements. Also, additional capacity allows more circuits to be added for future use.

How Much Power Do You Need?

Generators produce AC voltage, very similar to the voltage available in your home, however while your electric utility company produces sufficient power for all your electric powered devices, a home standby generator is limited in power output directly related to the engine horsepower. The amount of power that a generator can produce is rated in watts. Rated power is less than peak power as certain components lose efficiency as they are heated from use.

To determine wattage requirements you should determine which devices need to be powered simultaneously and what are the starting requirements. The wattage chart is provided below to assist you. Remember that with simple “power management” techniques, a small generator can provide adequate power for home or recreational applications.

The wattages listed below are based on estimated wattage requirements. For exact wattages, check the data plate or operator’s manual of the item you wish to power. Some appliances need a “surge” of energy when starting. This means that the amount of electrical power needed to start the appliance may exceed the amount needed to maintain its use. Electrical appliances and tools normally come with a label indicating voltage, cycles/Hz, amperage (amps) and electrical power needed to run the appliance or tool.
