Operation
Inverter Loads
The inverter will operate most AC loads continuously within its power rating of 4000 W. 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 inverter. Please read “High Surge Loads” and “Trouble Loads” carefully.
High Surge Loads
Some induction motors used in freezers, pumps, and other
If a motor refuses to start, observe the BATTERY VOLTAGE INDICATOR while trying to start the motor. If the indicator drops below 11 V while the inverter is trying to start the motor, this low voltage condition may be why the motor won’t start. Make sure that the battery connections are good and that the battery is fully charged. If the connections are good and the battery is charged, but the voltage still drops below 11 V, you may need to use a larger battery or DC input cables that are larger gauge and/or shorter length.
Trouble Loads
CAUTION: Equipment damage
Some equipment may be damaged by the inverter’s modified sine wave output.
Some appliances, including the types listed below, may be damaged if they are connected to the inverter:
•Electronics that modulate RF (radio frequency) signals on the AC line will not work and may be damaged.
•Speed controllers found in some fans, power tools, kitchen appliances, and other loads may be damaged.
•Some chargers for small rechargeable batteries can be damaged. See “Precautions for Using Rechargeable Appliances” on page vii for details.
•Metal halide arc (HMI) lights can be damaged.
If you are unsure about powering any device with the inverter, contact the manufacturer of the device.
