Generator 
insulation fault
There is an insulation fault on the 
PV generator. The feed-in was 
interrupted.
 Notify your
authorised 
electrician if the 
fault occurs several 
times.

The current and voltage 
measurements in the inverter are not 
plausible.

Fault
Self-test
The internal grid separation relay test 
has failed. 
 Notify your
authorised 
electrician if the 
fault occurs several 
times.

33
Fault
DC feed-in
The DC feed-in has exceeded the 
permitted value. This DC feed-in can 
be adopted from the grid onto the 
inverter so that no fault occurs.
 Notify your
authorised 
electrician if the 
fault occurs several 
times.

Internal 
communication 
error
A communication error has occurred 
in the internal data transmission. 
 Notify your
authorised 
electrician.

 Check the data
cable.

Protect. shutdown 
SW
Protective shutdown of the 
software (AC overvoltage, AC 
overcurrent, DC link overvoltage, DC 
overvoltage, DC overtemperature). 
Not a fault Grid-related 
 shutdown, the grid connects 
again automatically.
FS
36
Protect. shutdown 
HW
Protective shutdown of the 
hardware (AC overvoltage, AC 
overcurrent, DC link overvoltage). 
Not a fault Grid-related 
 shutdown, the grid connects 
again automatically.
FS

Generator 
overvoltage error
The voltage of the DC generator 
is too high. The PV generator is 
confi gured incorrectly. 
 Notify your
authorised 
electrician.

Line failure:
Under voltage L1, 
Over voltage L1
The voltage of a grid phase is too low 
or high; the grid cannot be fed into. 
The phase experiencing failure is 
displayed.
 Notify your
authorised 
electrician.

Line failure: line-to-
line voltage
The measured line-to-line voltage is 
outside of the tolerance limits.

Line failure:
Under frequency
Grid frequency is too low.
This fault may be grid-related.
