Add up all the Running (Rated) Watts required to operate your appliances. Now find the item with the highest Additional Starting Watts.

Add this number to your total to find the Total Watts needed for your portable generator / LPG generator.

ApplianceRunning (Rated) WattsAdditional Starting Watts
Refrigerator 700 220
Television 500 0
1/2 HP Furnace Fan 800 2350
Lights (6x75Watts) 450 0
Total Running (Rated) Watts 2450
(Highest) Additional Starting Watts 2350
Total Starting Watts 4800

1. Add up all the Running (Rated) Watts to achieve the Total Running (Rated) Watts.
2. Add the highest Additional Starting Watts to the Total Running (Rated) Watts to achieve the Total Starting Watts.

In this example, you will need a portable generator that produces at least 2450 Total Running (Rated) Watts, and 4800 Total Starting Watts. In this example the 5kW generator would be required.


Using the numbers you calculated in Step 2, find the portable generator that best suits your energy needs.
