Code Description
301 Current peak found on grid
302 Current peak found on PV
generator
303 Heat sink temperature too
high
306 POWER LOW
307 DC LOW
308 The intermediate circuit
voltage exceeds max. per-
missible limit
100
Behavior
1. Voltage drop in public grid
2. Grid impedance outside of
permissible values
3. Bad contact: wall bracket <-
-> inverter
4. Measurement error on filter
PC board
5. Incorrect capacity on device
1. Bad contact: wall bracket <-
-> inverter
2. Voltage drop in public grid
3. Measurement error on pow-
er module
1. Ventilation opening blocked
2. Ambient temperature too
high
3. Internal or external fans not
connected
4. Internal or external fans
faulty
5. Bad contact: power module
<--> heat sink
6. Measurement error on pow-
er module
7. Ventilator power on Recerbo
faulty
1. DC power too low for infeed
2. Measurement error on pow-
er module
1. Open the main DC switch.
2. PV generator not connected
3. DC voltage too low for infeed
4. Reverse voltage of PV gen-
erator
5. DC operating mode: fixed
voltage + incorrect voltage
6. Measurement error on pow-
er module
1. Voltage drop in alternating
current grid
2. Bad contact: wall bracket <-
-> inverter
3. Measurement error on pow-
er module
