502
An isolation fault between
DC+ / DC- to earth has
been detected
1. Isolation fault at the PV gen-
erator
1. Check cables and PV gener-
ator
509
No feed-in operation for 24
hours
1. Snow covered or very dirty
modules
1. Clean modules or remove
snow
2. Insufficient power from the
modules for feed in operation
2. Check other service codes
515
EEPROM communication
failure
1. Occurs once
1. Restart inverter
2. Filter calibration value not
correct
2. Change AC board. After-
wards if necessary DC board
516
Communication error inside
the power stage set
1. Occurs once
1. Restart inverter
2. Power stage set defective
2. Change board
517
Power stage set derating
caused by too high temper-
ature
1. Ventilation opening blocked
1. Clean openings
2. Too high ambient tempera-
ture
2. Change mounting place
3. Fan cables not connected
3. Connect fan cables
4. Fan defective
4. Change fan
5. Bad contact: power modul <-
> heat sink
5. Check phase change paste
6. Filter board defective
6. Change filter board
7. Recerbo defective
7. Change Recerbo
8. Measuring error on the pow-
er stage set
8. Change board
519
Communication error inside
the power stage set
1. Occurs once
1. Restart inverter
2. Filter board defective
2. Change filter board
520
No feed-in fpr 24 hours from
DC1 Input
1. Snow covered or very dirty
modules
1. Clean modules or remove
snow
2. Insufficient power from the
modules for feed in operation
2. Check other service codes
3. Input not used
3. Configure inverter as mon-
ostring
521
No feed-in fpr 24 hours from
DC2 Input
1. Snow covered or very dirty
modules
1. Clean modules or remove
snow
2. Insufficient power from the
modules for feed in operation
2. Check other service codes
3. Input not used
3. Configure inverter as mon-
ostring
522
DC LOW Ch1
1. DC main switch open
1. Close DC main switch
2. PV generator not connected
2. Connect PV generator
3. DC voltage too low for feed-
ing in
3. Wait for more irradiance or
check modules
4. Reversal voltage of PV gen-
erator
4. Change polarity of PV gen-
erator
5. DC operating mode: fix volt-
age and wrong voltage
5. Check MPP settings / volt-
age
6. Measuring error on the pow-
er stage set
6. Change DC board. After-
wards if necessary AC board
