Description
The grid 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 grid 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 grid voltage 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 grid voltage at the inverter is greater than the maximum 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 output voltage averaged over the legally prescribed period of time
lies outside the permissible tolerance range. 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. The inverter switches off due to legally prescribed
requirements and waits for a prescribed time before switching on again.
If the fault remains present, the inverter switches off again.
Contact your installer.

The residual current exceeds the permissible value. Due to legal require-
ments, the inverter switches automatically off while the error state is
present.
Contact your installer.

The isolation 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.

At least one of the internal fans of the inverter is faulty. In certain situa-
tions the inverter will feed less power into the grid (derating).
Contact your installer.

Despite power reduction, the maximum permissible internal 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. Check that the cooling fins and ventilation grill are free from soiling;
see Section 12, p. 75.
3. Contact your installer if this message occurs frequently.
The input voltage at the inverter is greater than the maximum permissible
value.
Switch off the main DC switch at the inverter and contact your in-

staller.
There is no grid voltage present (inverter running independently). For
safety reasons, the inverter must not feed into the grid.
Contact your installer if this error occurs frequently.

the grid for too long. Yields cannot be stored and event messages will
have the wrong date.
Correct the time under Settings / Time/Date.
