Status codes

Service class 1
Status codes of these class only arise momentarily and are caused by the public grid.
The initial response of the inverter in this case is to disconnect itself from the grid. The grid
is subsequently checked for the stipulated monitoring period. If no further problem has
been detected by the end of this period, then the inverter will resume feeding energy into
the grid.
Code Description
102 Grid voltage above permit-
ted limit
103 Grid voltage below permit-
ted limit
105 Mains frequency above
permitted limit
106 Mains frequency below per-
mitted limit
106
Check the AC voltage ON the inverter connections:
the AC voltage must be 230 V (+ 10 % / - 5 %)*
Carrying out an AC reset: Disconnect the inverter when not under load from the AC
supply and switch it back on
The mains voltage tolerance depends on the country setup
