Error Message
Grid voltage is not correct (overvoltage or undervoltage), thus
inhibiting the grid-feeding process.
The grid frequency is not correct (excessive or low frequency),
making the grid-feeding process impossible.
There is an impedance jump in the AC network. This can be
caused by e.g. bridging high capacity.
A grid voltage error, grid current problem, grid frequency or grid
impedance problem has occurred. The inverter has switched off
to protect against damage.
8
An internal failure occurred. It will clear itself and the unit starts
again.
