Event number
Message, cause and corrective measures
8003
Derating occurred
The inverter at Lxx reduces the battery charging current due to overheating.
Corrective measures:
• Reduce the total power of the loads, e.g. by staggering their use over time.
• Clean the fan (see Section 11.7, page 97).
• If the inverter reduces its power often, increase the power (install a more powerful
device type or more inverters of the same type).

Communication failure
The cause must be determined by the Service.
Corrective measures:
• Contact the Service.
8609
A slave is in error state, cluster is stopped
A slave has a fault status, cluster is stopped.
Corrective measures:
• Read off the pending and logged warnings and errors and eliminate the causes.
• Contact the Service.
8610
8611
Error in the cluster configuration
The addresses of the slaves in the cluster are incorrect.
Corrective measures:
• Change the addresses of the slaves in the cluster.
8612
No message from cluster master (only slave)
Communication to the master is interrupted.
Corrective measures:
• 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.
8613
Cluster incomplete
Voltage of the main cluster cannot be measured at Lxx.
Corrective measures
• Ensure that all miniature circuit breakers of the Sunny Island inverters in the Multicluster-
Box are closed.
• Ensure that the cabling at connection
AC1
is correctly installed.
