The allowable XPower Plus input voltage ranges are shown in the
following table:
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
Operating
Condition
Voltage Range Comment
Normal 10 V–15 V
Optimum
Performance 12 V–13 V
Low Voltage Alarm 10.7 V or less The audible low battery alarm sounds.
Low Voltage
Shutdown less than 10 V The inverter shuts down to protect the
battery from being over-discharged.
High Voltage
Shutdown 15 V or more The inverter shuts down to protect
itself from excessive input voltage.
Note: Although the XPower Plus
incorporates over-voltage protection,
it can still be damaged if input voltage
exceeds 16 V.
