Below are power calculators to help you determine the size of generator needed for your application. You can also calculate unit conversions and other power related calculations.
**DISCLAIMER: Electrical calculations are often complex. Besides “run” current, there are many other factors to consider. E.g. ambient temperature, altitude, iron losses, motor efficiencies, etc. The power calculators below are offered only to assist in formulating general estimations. Please seek the assistance of a certified electrician. If you would like assistance analyzing your current situation, please feel welcome to contact us.
To correctly determining the needed generator size, you must do more than simple add the wattage ratings of the devices the generator will power. For example, the “starting” current needed by an air conditioning unit is much greater than the “run” current for that same unit. If the “run” current is the only thing considered, the generator selected may easily be unable to handle the load.
A generator’s typical “load” may include air conditioning units, heating, lights, refrigerators and appliances, battery charges/inverters, and audio/video equipment. Several involved calculations are needed to determine the total electrical and mechanical demand that a generator must be able to satisfy.
