Cause
Remedy
01
PV overvoltage
Check voltage of the solar modules
The voltage must be lower than 100 V for the
30 A version, and smaller than 150 V for the
50 A version
If the voltage of the solar modules is within the
permitted range, contact the service
02
Internal memory
error
Restart the device
If the problem persists, contact the service
03
Charging current
too high
Restart the device
If the problem persists, contact the service
04
Temperature sensor
defective
Restart the device
If the problem persists, contact the service
05
Excessive
temperature
Switch device off and restart after some time
If the problem persists, contact the service
07
Battery voltage too
low
Measure battery voltage and check setting in
program 01:
- If a 12 V battery is connected, "AUT" or 12.0 V
must be set in program 01
- If a 24 V battery is connected, "AUT" or 24.0 V
must be set in program 01
Compare the measured value for the battery
voltage and the display on the device. In the
event of discrepancy, contact the service
08
Battery voltage too
high
Measure battery voltage and check setting in
program 01:
- If a 24 V battery is connected, "AUT" or 24.0 V
must be set in program 01
- If a 48 V battery is connected, "AUT" or 48.0 V
must be set in program 01 (only applies to the
50 A version)
Compare the measured value for the battery
voltage and the display on the device. In the
event of discrepancy, contact the service
