Behaviour
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
1. Occurs once
2. Occurs permanently
1. Auto test Italy was started
and not finished or failed
1. Defective temperature sen-
sor μC
2. Defective circuit on the pow-
er stage
1. Defective temperature sen-
sor in DC module 2
2. Defective circuit on the pow-
er stage
1. Grounding problem
Remedy
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
