Operation

Inverter Loads

The PROwatt 1000 will operate most AC loads within its power rating (1000 watts / 8 amps). 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 PROwatt 1000. Please read “Problem Loads”and “Trouble Loads” carefully.

Problem Loads

Some induction motors used in freezers, pumps, and other motor-operated equipment need high surge currents to start. The PROwatt 1000 may not be able to start some of these motors even though their rated current draw is within the inverter’s limits. The PROwatt 1000 will normally start single-phase induction motors rated at 1/2 horsepower or less.

If a motor refuses to start, observe the VOLTS indicator while you are trying to start the motor. If the indicator drops below 11 volts while the Prowatt 1000 is trying to start the motor, this may explain why the motor won’t start. Make sure the length and diameter of the battery cables are appropriate. Check that the battery connections are good and that the battery is fully charged. If the cables are sized correctly, the connections are good, and the battery is charged, but the voltage still drops below 11 volts, you may need to use a larger battery.

Trouble Loads

CAUTION

Some equipment may be damaged by the PROwatt 1000’s quasi-square wave output.

Some appliances, including the types listed below, may be damaged if they are connected to the PROwatt 1000:

•Electronics that modulate RF (radio frequency) signals on the AC line will not work and may be damaged.

•Speed controllers found in some fans, kitchen appliances, and other loads may be damaged.

•Some rechargers for small nickel-cadmium batteries can be damaged. See “Precautions For Using Rechargeable Appliances” on page viii for details.

If you are unsure about powering any device with the PROwatt 1000, contact the manufacturer of the device.
