Explanation
!
In case of overheating, the inverter
switches off . Possible causes:
• ambient temperature too high,
fan covered,
inverter defective.
Residual current was detected. The
feed-in was interrupted.
A ground fault was detected at the PV
generator.
The current and voltage measure-
ments in the inverter are not within
acceptable range.
An fault has occurred in the AC/
DC-sensitive residual current device.
The internal grid separation relay test
has failed.
The DC feed-in has exceeded the per-
mitted value. This DC feed-in can be
caused by grid conditions and may not
necessarily indicate a fault.
A communication error has occurred
in the internal data transmission.
Protective shutdown of the software
(AC overvoltage, AC overcurrent, DC
link overvoltage, DC overvoltage).
Protective shutdown of the
hardware (AC overvoltage, AC overcur-
rent, DC link overvoltage).
The voltage of the DC generator is too
high. The PV generator is confi gured
incorrectly.
The voltage of a grid phase is too low;
the grid cannot be fed into. The phase
experiencing failure is displayed.
