Troubleshooting
This unit features eight LED indicators and an alarm buzzer to help diagnose any malfunctions.
In the event of malfunction, the inverter will sound the buzzer to alert you prior to shutting
down its output. You should immediately check which LEDs are glowing to determine the
cause of the malfunction.
LED / Issue
Meaning
LOW VOLTAGE LED is ON
The input voltage is too low for normal operation.
Fix:
Check that the power source is appropriately rated for the application.
Check that the input wiring and connections are not corroded or dam-
aged.
If using
InverterWizard
, check the Low Voltage Alarm parameters are
properly set for the voltage of battery you are using, for example: 21V for
a 24V battery and 28V for a 32V battery.
If the above are checked and in working order, the cause is likely an
internal component failure and the unit must be returned for repair.
HIGH VOLTAGE LED is ON
The input voltage is too high for normal operation.
Fix:
Check that the power source is appropriately rated for the application
The inverter can be damaged if the input voltage exceeds the rating indi-
cated on the label. Over-voltage damage is not covered under warranty.
If the above are checked and in working order, the cause is likely an
internal component failure and the unit must be returned for repair.
OVER TEMP LED is ON
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.
The inverter will automatically derate its max. power rating to try to
maintain a safe operating temperature. If the internal temperature
exceeds the safe maximum, the unit will shut off its outputs. When the
temperature drops to safe operating range, the inverter will autorecover.
If the fans are NOT running,the unit must be returned for repair.
OVER LOAD LED is ON
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.
TIP:
FOR QUICK REFERENCE, IF THE UNIT IS EXPERIENCING A MALFUNCTION THE
INVERT LED WILL BE OFF AND ALSO THE BYPASS LED WILL GLOW RED.
