Error Causes
This table refers to 05 Error Causes Menu messages. Refer to these
messages when the ERROR LED is on or flashing.
Message Problem Solution
05A Over Current Excessive load on the AC
output. Reset the inverter by pressing the On/Off switch to
OFF, then to SRCH or ON. If unit comes on, then
check for a heavy load (above the inverter’s
capacity) on the inverter’s output. If the 05A Over
Current error happens again, disconnect all wires on
the AC input and output and reset the inverter again.
If the inverter comes on, then check your AC wire
system for shorts or miswired connections.
05B Transformer
Overtemp or
05C Heatsink
Overtemp AC input voltage may be
too high while charging.
Operating too large of a
load for too long while
inverting.
Ambient temperature may
be high.
Inverter cooling fan may
have failed.
Inverter airflow intake
may be blocked.
Charging setting is too
high based on ambient
temperature around
inverter.
Check for high input AC voltage.
Remove excessive loads.
Let inverter cooldown and try restarting.
Hold a piece of paper to inverter vents to check the
fan (the fan is hard to hear). If the fan has failed, have
the inverter serviced.
Increase clearance around the inverter or unclog the
fan air intake.
Lower the 12E Max Charge Amps AC setting.
05D Low Battery
Voltage Battery voltage is below
the 11C Low Battery
Cut Out VDC settings. Check for the correct battery voltage at the inverter’s
DC input terminals. Check for an external DC load
on the batteries. Check condition of batteries and
recharge if possible or adjust your
11C Low Battery Cut Out VDC to a lower setting.
05E High Battery
Voltage Battery voltage is above
the 11A High Battery
Cut Out VDC settings. Check for the correct battery voltage at the inverter’s
DC input terminals. Ensure your DC source is
regulated below your high battery cut out or adjust
your 11A High Battery Cut Out VDC to a higher
setting.
