4–2
The remote control LEDs are numbered by counting up from the bottom.
LED Number
Indication
1
Illuminates if the unit shuts down for any reason.
2
Over-temperature. Allow to cool.
3
The unit detected a failure. Call Xantrex technical support.
4
Inverter overload caused by too large a load or short circuit. Reset by
cycling power switch or plugging in incoming AC power.
5
Battery overload caused by excessively discharged batteries. See
page 3–15.
6
Incoming AC backfeed. Potentially damaging to the unit. Disconnect
incoming AC power and correct the condition.
7
Triac thermal run away. Turn off and allow to cool down.
8
High battery voltage shutdown during charge mode. Check all charging
sources for proper voltage. Reset by cycling the power switch.
9 and 10
Not used for troubleshooting.
Problem
Things to Check
No inverter
•
Battery voltage under load.
output
•
Battery connections and DC fuse.
•
Circuit breaker on front panel.
•
Thermal condition, high power loads or inadequate ventilation may
cause overheating.
•
Overloads or short circuit, check for excessive loads or bad wiring
connections.
Low inverter
Confirm that your volt meter is a true RMS meter. Standard volt meters
output
will not accurately read the waveform of the inverter and may read
voltage
anywhere from 180 VAC to 240 VAC. If a true RMS meter is not
available, check the brightness of an incandescent light bulb. If it
appears normal, the output voltage is properly regulated.

watts.
•
AC reverse polarity—check for voltage between the incoming blue
and green wires. If 240 volts AC is measured, this is reverse polarity.
Microwave

Microwave ovens will normally cook slowly on inverters due to a
oven cooking
slightly low peak AC voltage.
slowly
•
Cooking speed will be determined by battery voltage. Low voltage
results in increased cooking time. Support the battery bank with an
alternator or other charging source for quicker cooking.
