Symptom
Possible Cause
Recommended Solution
No output power.
Inverter LED is
OFF
Inverter is switched OFF
Turn the Inverter ON
Battery voltage is too low. The battery voltage
level has dropped below the Low Battery Cut
Off (LBCO)
Check all connections for a break in the circuit:
Fuses, Circuit breakers, Cable terminals. The
Batteries need charging.
Battery voltage is too high. The Inverter
automatically resets and resumes operation
when the battery voltage level has dropped
below the HBCI set point.
This condition usually only occurs when an
additional charging source (solar panels) is used
to charge the batteries. Remove or disconnect the
additional charging source so the voltage of the
battery bank can drop.
Over-temperature condition: The internal
temperature of the Inverter has risen above
acceptable limits; caused by loads too great
for the inverter to operate continuously, or by
lack of ventilation to the Inverter.
Reduce the AC loads (appliances) that are
operating.
Check ventilation around the Inverter. Ensure all
ventilation openings are clear and un-obstructed
AC over-load condition: The inverter has
turned off because the connected loads are
larger than the Inverter/Chargers output
capacity, or the output wires are shorted.
Reset the unit by holding down the main On/Off
button on the top left of the Inverter/Charger. If this
does not remedy the issue, disconnect from DC
power and try again.
Internal fault.
To clear this fault, an Inverter reset is required.
Remove DC power to the Inverter, or press and
hold down the ON/OFF switch for 15 seconds.
No output power.
Inverter LED is
ON
Unit is in search mode, which means load is
too small for search mode circuit detection.
Turn on a load greater than 5 watts to bring
Inverter/Charger to full output power, or turn off
search function with the IC Series Remote.
Low output or
surge power.
Inverter LED is
ON
Loose or corroded battery cables.
Clean and tighten all cables.
Low batteries.
Recharge or replace batteries.
Loose AC output connections.
Tighten AC output connections.
Battery cables are the wrong length or gauge.
Verify recommended cable lengths and gauges
from the manual. Replace cables as necessary.
Low charging rate
when connected
to AC Utility
Power
Charge rate set too low.
Adjust charge rate or shore settings on remote
Low AC voltage (< 90 VAC).
Check AC input wiring.
Low charging rate
when connected
generator
Generator output is too low to power both load
and charger.
Reduce the load, and increase the generator’s
RPMs.
Adjust charge rate or shore settings on remote.
Charger does not
charge
Loose or corroded battery cables.
Clean and tighten battery cables.
Defective batteries.
Replace batteries.
Wrong charger settings.
Adjust the charger settings.
Wrong AC input voltage.
Verify proper AC input voltage.
