Inverter Operation
Inverter Loads
The XPower Inverter 1000 will operate most AC loads within its power
rating. 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 motor-operated
equipment require high surge currents to start. The inverter may not be able
to start some of these motors even though their rated current draw is within
the inverter’s limits. The inverter will normally start single-phase induction
motors rated at 1/2 horsepower or less.
Trouble Loads
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 viii 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.
Connecting Appliances to the Inverter
Since regular amounts of AC current flows between the inverter and your
appliances, commonly available extension cords can be used to connect the
inverter to your appliances. If your appliance will be connected at a
considerable distance from the inverter, it is much more practical and less
expensive to lengthen the AC wiring than it is to lengthen the DC wiring.
Routine Maintenance
Maintaining the Inverter
Minimal maintenance is required to keep your inverter operating properly.
Periodically you should:
• clean the exterior of the unit with a damp cloth to prevent the
accumulation of dust and dirt,
• ensure that the DC cables are secure and fasteners are tight, and
• make sure the ventilation openings on the DC panel and bottom of the
inverter are not clogged.
