Troubleshooting
This unit features eight LED indicators and an alarm buzzer to help diagnose any malfunctions.
The Inverter will sound the buzzer to alert you prior to shutting down. You should immediately
check the LED indicators to determine the cause of the shutdown.
LED Indicator
Meaning
LOW VOLTAGE
The input voltage is too low for normal operation.
Fix:
Check that the rating of the DC power source is appropriate for the
application. Check that the input cables and connections are not
corroded or damaged.
If using InverterWizard, check the Low Voltage parameters are set
properly for the battery voltage you are using, for example: 21V for a
24V battery and 28V for a 32V battery.
If everything else is normal, the cause is likely an internal compo-
nent failure and the unit must be returned for repair.
HIGH VOLTAGE
The input voltage is too high for normal operation.
Fix:
Check that the rating of the DC power source is appropriate for
the application. The Inverter can be damaged if the input voltage
exceeds the maximum rating. Over-voltage damage is not covered
under warranty.
If the power source is functioning correctly, the cause is likely an
internal component failure and the unit must be returned for repair.
OVER TEMP
The unit’s internal temperature is too hot for normal operation.
Fix:
Check that the unit’s cooling fans are functioning. If the fans are run-
ning, you may need to remount the Inverter for improved ventilation.
If the fans are NOT running, the Inverter must be returned to the
manufacturer for repair.
OVER LOAD
The load is drawing too much current from the Inverter
Fix:
The unit has been operating at peak current for longer than its
intended duty cycle. Reduce the load by disconnecting some devices
from the unit’s AC output.
