Symbol Cause
The mains frequency that is present at the
inverter exceeds the permissible value.
Due to legal regulations, the inverter
automatically switches off while the fault is
present.
The mains frequency that is present at the
inverter falls below the permissible value.
Due to legal regulations, the inverter
automatically switches off while the fault is
present.
The inverter has detected that a network
relay is defective and therefore does not
feed into the network.
After switching off, the inverter cannot con-
tinue to feed in because the mains voltage
falls below the statutory activation value.
The output voltage that is averaged over a
statutory period of time exceeds the permiss-
ible tolerance range.
The inverter automatically switches off while
the fault is present.
The output voltage that is averaged over
a statutory period of time falls below the
permissible tolerance range.
The inverter automatically switches off while
the fault is present.
The mains voltage that is present at the
inverter exceeds the permissible value.
Due to legal regulations, the inverter
automatically switches off while the fault is
present.
After switching off, the inverter cannot con-
tinue to feed in because the mains voltage
exceeds the statutory activation value.
The mains voltage that is present at the
inverter falls below the permissible value.
Due to legal regulations, the inverter
automatically switches off while the fault is
present.
The proportion of direct current power that is
fed into the network by the inverter exceeds
the permissible value.
Due to legal regulations, the inverter
automatically switches off while the fault is
present.
The input voltage that is present at the in-
verter exceeds the permissible value.
The input current at the inverter exceeds the
permissible value.
The inverter limits the current to the permiss-
ible value.
Communication with the inverter is not pos-
sible via the RS485 interface.

–
Ensure that the photovoltaic voltage is
lower than the maximum input voltage
for the inverter.
–
Ensure that the photovoltaic generator
is correctly dimensioned for use with the
inverter.
