Current peak on the PV
generator
1. Bad contact: wall bracket <-
> inverter
1. Check AC wall bracket
screws
2. Voltage drop in the public
mains
2. Automatic correction
3. Measuring error on the pow-
er stage set
3. Change DC board. After-
wards if necessary AC board
303
Too high heat sink temper-
ature
1. Ventilation opening blocked
1. Clean openings
2. Too high ambient tempera-
ture
2. Change mounting place
3. In- or outside fan cable not
connected
3. Connect fan cable
4. In- or outside fan defective
4. Change fan
5. Bad contact: wall bracket <-
> heat sink
5. Check phase change paste
6. Measuring error on the pow-
er stage set
6. Change AC board
7. Fan output on Recerbo de-
fective
7. Change Recerbo
306
POWER LOW
1. DC power is too low for feed-
ing in
1. Wait for more irradiance or
check PV modules
2. Measuring error on the pow-
er stage set
2. Change DC board. After-
wards if necessary AC board
307
DC LOW
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 PV modules
4. Reversal voltage of PV gen-
erator
4. Reverse polarity of PV gen-
erator
5. DC operation mode: fix volt-
age + 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
308
The intermediate circuit
voltage
1. Voltage drop on AC grid
1. Automatic correction
2. Bad contact: wall bracket <-
> inverter
2. Check AC wall bracket
screws
3. Measuring error on the pow-
er stage set
3. Change AC board
309
Too high DC1 voltage
1. PV generator voltage too
high in MPP1
1. Check PV configuration
2. Wrong DC cabling in MPP 1
2. Check DC cabling
3. Measuring error on the pow-
er stage set
3. Change DC board. After-
wards if necessary AC board
313
Too high DC2 voltage
1. PV generator voltage too
high in MPP 2
1. Check PV configuration
2. Wrong DC cabling in MPP 2
2. Check DC cabling
3. Measuring error on the pow-
er stage set
3. Change DC board. After-
wards if necessary AC board
