Behaviour
1. Snow covered or very dirty
modules
2. Insufficient power from the
modules for feed in operation
3. Input not used
1. DC main switch open
2. PV generator not connected
3. DC voltage too low for feed-
ing in
4. Reversal voltage of PV gen-
erator
5. DC operating mode: fix volt-
age and wrong voltage
6. Measuring error on the pow-
er stage set
1. DC main switch open
2. PV generator not connected
3. DC voltage too low for feed-
ing in
4. Reversal voltage of PV gen-
erator
5. DC operating mode: fix volt-
age and wrong voltage
6. Measuring error on the pow-
er stage set
1. Old software
2. Old software
3. Incompatible hardware com-
binations
1. Old software
2. Old software
3. Incompatible hardware com-
binations
1. Too high grid frequency
2. Grid disturbances
3. Wrong settings
1. Writing data to SD card
failed
1. No error, AFCI is deactivat-
ed
1. Too high grid voltage
2. Grid disturbances
3. Wrong settings
An external custom device per-
forms a signal state change
1. Occurs once
2. Occurs permanently
Remedy
1. Clean modules or remove
snow
2. Check other service codes
3. Configure inverter as mon-
ostring
1. Close DC main switch
2. Connect PV generator
3. Wait for more irradiance or
check modules
4. Change polarity of PV gen-
erator
5. Check MPP settings / volt-
age
6. Change DC board. After-
wards if necessary AC board
1. Close DC main switch

3. Check settings
1. Format SD card
1. If AFCI has to be switched
on, use tool
1. Automatically corrected
2. Software update
3. Check settings
Check the external signal or
the input signal configuration
1. Restart inverter
