Event number Message, cause and corrective measures
8615
Box encoding does not correspond to software settings
Box coding conflicts with software settings: Configuration of the Sunny Island inverters does
not match the Multicluster-Box.
Corrective measures:
8616
Cluster incomplete
Due to a short circuit on the load side, the supply voltage of the Sunny Island at line conduc-
tor Lxx drops and can no longer be maintained. This causes the voltage supply of contactor
Q10/Q110 of the Multicluster-Box to fail.
Corrective measures:
8617
Extension clusters have a country data set configured that is different to that of the
main cluster
At least in 1 extension cluster, the Sunny Islands are set to another country standard than the
Sunny Islands in the main cluster.
