Status Display Explanation Action By
OS 11 Measured values Power limitation: If the generator
power is too high, the inverter limits
itself to the maximum power (e.g. in
the midday hours if the generator has
been too largely dimensioned).
- -
OS 29 Check ground
fault fuse
A ground fault was detected on the
DC side.
 Check the PV gen-
erator
E
FS 30 Voltage
trans. fault
The current and voltage measure-
ments in the inverter are not plausible.
- -
FS 32 Fault
Self-test
The internal grid separation relay test
has failed.
 Notify your author-
ised electrician if the
fault occurs several
times.
E
FS 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 author-
ised electrician if the
fault occurs several
times.
E
FS 34 Internal commu-
nication error
A communication error has occurred
in the internal data transmission.
 Notify your author-
ised electrician.
E
 Check the data
cable.
FS 35 Protect. shut-
down SW
Protection 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. shut-
down HW
Protection shutdown of the hardware
(AC overvoltage, AC overcurrent, DC
link overvoltage).
Not a fault
Grid-related shutdown,
the grid connects again
automatically.
-
FS 38 Generator over-
voltage error
The voltage of the DC generator is too
high. The PV generator is incorrectly
dimensioned.
 Notify your author-
ised electrician.
E
FS 41 Line failure:
undervolt. L1
The voltage of a grid phase is too low;
the grid cannot be fed into. The phase
experiencing failure is displayed.
 Notify your author-
ised electrician.
E
FS 42 Line failure:
overvolt. L1
The voltage of a grid phase is too high,
the grid cannot be fed into.
The phase experiencing failure is dis-
played.
 Notify your author-
ised electrician.
E
FS 43 Line failure:
undervolt. L2
The voltage of a grid phase is too low;
the grid cannot be fed into. The phase
experiencing failure is displayed.
 Notify your author-
ised electrician.
E
