Table 2.1 provides a list of some common AC appliances / devices that require high, short
duration surge of power during start up. An “Inverter Sizing Factor” has been recom-
mended against each which is a Multiplication Factor to be applied to the Maximum
Continuous Running Power Rating (Active Power Rating in Watts) of the AC appliance
/ device to arrive at the Maximum Continuous Running Power Rating of the inverter
(Multiply the Maximum Continuous Running Power Rating (Active Power Rating in
Watts) of the appliance / device by recommended Sizing Factor to arrive at the Maxi-
mum Continuous Running Power Rating of the inverter.
TABLE 2.1: INVERTER SIZING FACTOR
Type of Device or Appliance
Inverter
Sizing Factor
(See note 1)
Air Conditioner / Refrigerator / Freezer (Compressor based) 5
Air Compressor 4
Sump Pump / Well Pump / Submersible Pump 3
Dishwasher / Clothes Washer 3
Microwave (where rated output power is the cooking power) 2
Furnace Fan 3
Industrial Motor 3
Portable Kerosene / Diesel Fuel Heater 3
Circular Saw / Bench Grinder 3
Incandescent / Halogen / Quartz Lamps 3
Laser Printer / Other Devices using Infrared Quartz Halogen Heaters 4
Switch Mode Power Supplies (SMPS): no Power Factor correction 2
Photographic Strobe / Flash Lights 4 (See Note 2)
NOTES FOR TABLE 2.1
1. Multiply the Maximum Continuous Running Power Rating (Active Power Rating in
Watts) of the appliance / device by the recommended Sizing Factor to arrive at the
Maximum Continuous Running Power Rating of the inverter.
2. For photographic strobe / flash unit, the Surge Power Rating of the inverter should be
> 4 times the Watt Sec rating of photographic strobe / flash unit.
