Inverter Loads

The XPower Plus will operate most AC loads within its power rating: 1000 watts for the XPower 1200 Plus and 1500 watts for the XPower 1750 Plus. However, some appliances and equipment may be difficult to operate, and other appliances may actually be damaged if you try to operate them with the XPower Plus. Please read “High Surge Loads” and “Trouble Loads” carefully.

High Surge Loads

Some induction motors used in freezers, pumps, and other motor-operated equipment require high surge currents to start. The XPower Plus may not be able to start some of these motors even though their rated current draw is within the inverter’s limits. The XPower Plus will normally start single- phase induction motors rated at 1/2 horsepower or less.

If a motor refuses to start, observe the INPUT VOLTAGE DISPLAY while trying to start the motor. If the indicator drops below 11 volts while the XPower Plus is trying to start the motor, this low voltage condition may
