Generator Sizing
A generator should be sized to provide enough power for all the loads and the battery charger.
¾ Available generator power may be limited by ratings for circuit breakers and/or generator connectors.
¾ The generator must be able to provide current to all inverters on a given phase or leg. Minimum generator
wattage 1 is usually recommended to be twice the wattage of the inverter system. Many generators may not
be able to maintain AC voltage or frequency for long periods of time if they are loaded more than 80% of
rated capacity.
NOTES:
1 This is the wattage value after deratings for the following: peak verses continuous power, load power factor considerations, fuel type,
altitude, and ambient temperature.
