Power Output
The XM 1800 can deliver up to 1000 watts (XM 1000) or 1800 watts
(XM 1800) continuous power. The wattage rating applies to resistive
loads such as incandescent lights.
Input Voltage
The allowable XM 1800 input voltage ranges are shown in the following
table:
Operating
Condition Voltage Range Comment
Normal 11–15.0 V
Optimum
Performance
12.0–13.0 V
Low Voltage Alarm 11.0 V or less The low battery alarm beeps once
every two seconds and the display
shows fault code E01 alternating with
the battery voltage.
Low Voltage
Shutdown
Less than
10.5 V
The low battery alarm beeps every
second and the display shows fault
code E02 alternating with the battery
voltage. The status LED turns red and
the inverter shuts down to protect the
battery from being over-discharged.
High Voltage
Shutdown
15.5 V or more The over-voltage alarm beeps every
second and the display shows fault
code E03 alternating with the battery
voltage. The status LED turns red and
the inverter shuts down to protect
itself from excessive input voltage.
Note: Although the XM 1800
incorporates over-voltage protection,
it can still be damaged if input
voltage exceeds 16 V.
