cAUSe
battery voltage too low Pre-charge the battery
The external fuse in
the battery connection
cable has blown.
battery is not
connected
battery is connected
with the wrong
polarity
battery is defective
Charging interrupted
due to excessive
charging current
( > 20A)
Load output is
switched off due to
excessive load current
Load output is
switched off due to
short circuit at load
output
Load output is
switched off due to
overheating of the
solar charge controller
Load output is
switched off due to
too low battery voltage
ReMeDy
replace the external fuse
1. Unclamp all connections
2. Connect a (new) battery with
the correct polarity
3. reconnect the solar module
and loads
Charging automatically continues
as soon as the charging current
lies within the permissible range
- reduce load current, if necessary
switch off or disconnect loads
- Check loads
- Disconnect loads
- Correct the cause of the short
circuit
- reconnect loads
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 load output automatically
switches oN again as soon as the
battery voltage lies within the
permissible range
- Pre-charge the battery
- Use additional Low Voltage
Disconnect (LVD) for loads > 20A
that are connected directly to
the battery
- Check the battery and replace
if necessary
