How to match your generator to your power demands.

1. First, discover your total electrical load, using the power chart. Make a list of all lights and electrical appliances you wish your generator to supply.

2. Establish your steady state load - the lights and appliances you expect to operate at any one time.

3. When electric motors form part of your appliances (see note below), calculate your maximum demand by adding the extra power required to start the electric motor to your steady state load.

4. Choose your generator to match your maximum power demand.

Note: Electric motors need more power to start than to run. Use the simple formula of 3 x the motor horsepower to add to your required kW. For motors starting under load (e.g compressors) or submersible
pumps, a higher value is required. This guide applies to modern motor design only.
