CHARGER FAULT MESSAGE
CAUSE
ACTION
Charger over current fault
An internal error has caused excessive
current draw
Return to supplier

The output voltage is too high (above
18V)
Check battery is correct type (12V, 6
cell)
Charger over temperature. Allow to cool
The unit has over heated
Allow to cool, charging will
recommence automatically

Output battery is below 0°C
Charger will halt charging until battery
is above 5°C
Output battery over temperature
Output battery is above 60°C
Charger will halt charging until battery
is below 55°C
Dry cell detected in output battery
Charger has detected a dry cell in
output battery
Replace battery
Shorted cell detected in output battery

Warnings
CHARGER WARNING MESSAGE
CAUSE
ACTION
AC supply over voltage
The internal AC converter output
voltage is too high
Contact supplier
AC supply over temperature. Allow to cool
The internal AC converter temperature
is too high
Contact supplier
DC supply over voltage
The DC input voltage is too high (over
32V)
Check DC input, refer to specified input
range
Solar supply over voltage
The solar input voltage is too high
(above 32V)
Check solar input, refer to specified
input range
No battery sensor connected
The supplied battery sensor is not
connected or is faulty
Connect battery sensor, if faulty return
to supplier
Battery SoC low! Disconnect all loads
House battery is almost flat
Reduce/remove loads on house battery
Battery voltage low! Disconnect all loads
Loads exceeding charge available from
input sources
Connect additional input source or
disconnect loads
Bad cable detected
Too much voltage drop between
charger and battery sensor
Check cable for correct sizing
requirements
Load Disconnect output shorted
Load disconnect output faulty
Contact supplier
Other issues
FAULT
ACTION
Low output current can occur when the unit is hot and
temperature derating is implemented to protect the Charger
Check that the unit is in a well ventilated space
The current display shows a negative current when there
are no loads on the house battery and the house battery is
charging
The current shunt connection is reversed
Noticable oscillations between Boost and Absorption stages
Check and select the correct battery type
