Event number Message, cause and corrective measures
8612
No message from cluster master (only slave)
Communication to the master is interrupted.
Corrective measures:
8613
Cluster incomplete
Voltage of the main cluster cannot be measured at L1 / L2 / L3.
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
The voltage supply of contactor Q10 /Q110 has failed due to a short circuit in the stand-
alone grid.
Corrective measures:
8617
Extension cluster has a country data set configured that is different to that of the
main cluster
At least in one extension cluster, the Sunny Islands are set to another country standard than
the Sunny Islands in the main cluster.
Corrective measures:
Operating Manual
• Ensure that undamaged CAT5e cables are used for communication and that the cables
are plugged in correctly.
• Ensure that the communication bus is equipped with a terminator at both ends.
• Ensure that all circuit breakers of the Sunny Island inverters in the Multicluster-Box are
closed.
• Ensure that the cabling at connection AC1 is correctly installed.
• Check whether the value set for parameter Type of AC subdistribution matches the
connected Multicluster-Box.
• If the value does not match, restart the installation assistant (see Section 9.1, page 118).
• Contact the Service (see Section 19, page 189).
• Eliminate the short circuit.
• Set the same country standard (parameter Country standard set) in all Sunny Island
inverters in the main cluster and in the extension cluster.
