6. Maintenance
The solar charge controller is maintenance-free.
All components of the PV system must be checked at least annually, according to the
specifications of the respective manufacturers.
Ensure adequate ventilation of the cooling element.
Check the cable strain relief.
Check that all cable connections are secure.
Tighten screws if necessary.
Terminal corrosion
7. Faults and remedies
Fault Cause Remedy
No display battery voltage too low • pre-charge the battery 
the external fuse in the
battery connection cable has
blown.
• replace the external fuse

battery is not connected • unclamp all connections
connect a (new) battery with
the correct polarity
reconnect the solar module
and loads

load output is switched off
due to excessive load current
• reduce load current, if neces-
sary switch off or disconnect
loads
check loads


load output is switched off
due to short circuit at load
output
• disconnect loads
correct the cause of the short
circuit
reconnect loads

load output is switched off
due to overheating of the
solar charge controller
• the load output automatically
switches on again once the
solar charge controller has
cooled down
improve the cooling air
circulation
remove any other heat
sources
check the conditions of use
and the mounting location

the battery voltage lies within
the permissible range
pre-charge the battery
equip loads directly con-
nected to the battery with
