Choosing The Right Generator for you!



  • 1KW =             1000W
  • 1KVA =             800W
  • 1HP =             750W
  • 1KVA =             4Amps (Single phase)
  • Watts =             Volts x Amps
  • Amps =             Watts/Volts

General Rule #1

Compressors and other induction motors (e.g. Fridges, freezers and air conditioners) will require a minimum of 3 times the HP of the motor to the KVA to start. For example, an air conditioner with 1HP motor will require 3KVA every time that motor cycles in.

General Rule #2

Common Applications – Welders & Compressors:

  • 120amp welder or 8CFM compressor requires a minimum of 5KVA
  • 140amp welder or 10CFM compressor requires a minimum of 6KVA
  • 160amp welder or 12CFM compressor requires a minimum of 7KVA
  • 180amp welder or 14CFM compressor requires a minimum 8KVA

General Rule #3

To work out the generator size required, simply add the wattage of all appliances or construction tools likely to be used at the same time. Don’t forget to allow for any induction motors. Use the Common formulas above to calculate your minimum KVA required.
