Recommissioning the Multicluster-Box

Load shedding in the first two operating hours
The state of charge (SOC) recorded by battery management and the available battery
capacity (SOH) will deviate strongly from the actual values of SOC and SOH for a newly
connected battery. During operation, the values recorded by battery management will
gradually approach the real values. In the first two operating hours with the new battery, these
deviations can lead to load shedding and corresponding messages. These messages will be
displayed on the Sunny Island user interface.
Requirements:
☐ The Multicluster-Box must be properly installed.
☐ All cables must be correctly connected.
☐ All cables must be tightly enclosed by a membrane or cable entry.
☐ All power cables must be secured inside or outside.
☐ The multicluster system must be grounded outside the Multicluster-Box on either the generator
side or the load side.
☐ The neutral conductor must be connected to the grounding conductor.
Procedure:
1. Ensure that the power cables are secured with a strain relief.
2. Close the Multicluster-Box.
3. Commission the multicluster system (see documentation of the Sunny Island).
4. In order to receive service assignments for the multicluster system, all system data must be
recorded in the information sheet for Sunny Island systems and made available to Service. To
do this, access the information sheet at www.SMA-Solar.com.
