 
Inverter Generator Load Chart
Sizing the right inverter generator for your needs can be
determined by adding up the combined loads of all the devices
you intend to power.
Wattage
Review the listed wattage on the device as
well as the startup wattage of any motor driven devices like
refrigerators, air conditioners and pumps. Choosing the
correctly sized generator for your load can help prevent damage
to the generator and devices as well saving you fuel. The chart
below provides approximate load information for common devices.
The following formula voltage x amps can be used to determine
watts.

 For a more accurate assessment of appliance efficiency and overall power consumption, consider the use of an electricity usage monitor. These devices are inexpensive and can help to cut costs as you discover which appliances and devices are consuming the most electricity. One of the most popular units available today is the P4400 Kill A Watt Electricity Usage Monitor manufactured by P3 International. This unit not only calculates electrical usage but also helps to evaluate the quality of the power being provided to appliances. It can be used to test outlets and under voltage conditions or brownouts.
