3 USER GUIDE
Faults
CHARGER FAULT MESSAGE
Charger over current fault
Charger over voltage fault
Unit over temperature fault. Allow to cool
Output battery under temperature fault
Output battery over temperature fault
Dry cell detected in output battery
Shorted cell detected in output battery
Warnings
CHARGER WARNING MESSAGE
AC supply over voltage
AC supply over temperature
DC supply over voltage
Solar supply over voltage
No battery sensor connected
Low battery State of Charge
Bad cable detected
Load Disconnect output shorted
Battery voltage low! Disconnect all loads
Other issues
FAULT
Low output current can occur when the unit is hot and
temperature derating is implemented to protect the Charger
The current display shows a negative current when there
are no loads on the house battery and the house battery is
charging
Noticeable oscillations between Boost and Absorption stages Check and select the correct battery type
CAUSE
An internal error has caused excessive
current draw
The output voltage is too high (above
18V)
The unit has over heated
Output battery is below 32°F
Output battery is above 140°F
Charger has detected a dry cell in
output battery
Charger has detected a shorted cell in
output battery
CAUSE
The internal AC converter output
voltage is too high
The internal AC converter temperature
is too high
The DC input voltage is too high (over
32V)
The solar input voltage is too high
(above 32V)
The supplied battery sensor is not
connected or is faulty
House battery is almost flat
Too much voltage drop between
charger and battery sensor
Load disconnect output faulty
Loads exceeding charge available from
input sources
ACTION
Check that the unit is in a well ventilated space
The current shunt connection is reversed
33
ACTION
Return to supplier
Check battery is correct type (12V, 6
cell)
Allow to cool, charging will
recommence automatically
Charger will halt charging until battery
is above 41°F
Charger will halt charging until battery
is below 131°F
Replace battery
Replace battery
ACTION
Contact supplier
Contact supplier
Check DC input, refer to specified input
range
Check solar input, refer to specified
input range
Connect battery sensor, if faulty return
to supplier
Reduce/remove loads on house battery
Check cable for correct sizing
requirements
Contact supplier
Connect additional input source or
disconnect loads
