Xantrex PROwatt 1750, Owner'S Manual

Operation
4–6
Inverter Loads
The PROwatt 1750 will operate most AC loads within its power rating
(1750 watts / 15 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 1750. 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 1750 may not
be able to start some of these motors even though their rated current draw
is within the inverter’s limits. The PROwatt 1750 will normally start
single-phase induction motors rated at 3/4 horsepower or less.
If a motor refuses to start, observe the
VOLTS
indicator while trying to
start the motor. If the indicator drops below 11 V while the Prowatt 1750
is trying to start the motor, this 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.
Trouble Loads
Some appliances, including the types listed below, may be damaged if
they are connected to the PROwatt 1750:
•
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 1750,
contact the manufacturer of the device.
CAUTION
Some equipment may be damaged by the PROwatt 1750’s
quasi-square wave output.
