Description
The mains frequency at the inverter is less than the minimum permissible
value. Due to legal requirements, the inverter switches automatically off
while the error state is present.
Contact your installer if this error occurs frequently.

The mains frequency at the inverter is greater than the maximum permis-
sible value. Due to legal requirements, the inverter switches automatically
off while the error state is present.
Contact your installer if this error occurs frequently.

After switching off, the inverter cannot resume feeding because the grid
frequency exceeds the legally prescribed switch-on value.
Contact your installer if this error occurs frequently.

The mains voltage at the inverter is less than the minimum permissible
value for a short period of time. Due to legal requirements, the inverter
switches automatically off while the error state is present.
Contact your installer if this error occurs frequently.

The mains voltage at the inverter is greater than the maximum permis-
sible value for a short period of time. Due to legal requirements, the
inverter switches automatically off while the error state is present.
Contact your installer if this error occurs frequently.

The output voltage averaged over 10 minutes lies outside the permissible
tolerance range. Due to legal requirements, the inverter switches auto-
matically off while the error state is present.
Contact your installer if this error occurs frequently.

The DC current portion fed into the grid by the inverter exceeds the maxi-
mum permissible value. Due to legal requirements, the inverter switches
automatically off while the error state is present.
Contact your installer.

The residual current flowing from the positive or negative inputs to earth
via the photovoltaic modules exceeds the maximum permissible value.
Due to legal requirements, the inverter switches automatically off while
the error state is present.
Contact your installer.

reasons, the inverter must not feed into the grid.
Contact your installer.

The functional earthing conductor is not connected. For safety reasons
the inverter must not feed into the grid.
Contact your installer.

The insulation resistance between the positive or negative input and
earth is less than the permissible value. For safety reasons, the inverter
must not feed into the grid.
Contact your installer.

The internal fan of the inverter is faulty. In certain situations, the inverter
will feed less power into the grid (derating).
Contact your installer.

Despite derating, the maximum permissible temperature has been
exceeded. The inverter feeds no power into the grid until the maximum
permissible temperature is no longer exceeded.
1. Check that the installation conditions are satisfied.
2. Contact your installer if this message occurs frequently.
The DC input voltage at the inverter is greater than the maximum permis-
sible value.
Switch off the main DC switch at the inverter and contact your in-

staller.
The input current at the inverter exceeds the permissible value. The in-
verter limits the current to the permissible value.
Contact your installer if this message occurs frequently.
