Using the Remote Control DC Amps LED Bar Graph

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.
Little or no	• Wiring connections—check both the AC and DC connections.
output from	• AC input voltage—low voltage input will result in low DC output
battery	current. Expect reduced charger output from generators under 6500
charger	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.
