One-level load shedding is integrated into the Multicluster-Box. The load-shedding contactor is controlled directly by the master of the main cluster via communication with the Multicluster-Box. If you install an additional load-shedding contactor in a multicluster system, it is controlled with a multifunction relay in the master of extension cluster 1. Additional load-shedding contactors cannot be controlled by the main cluster.
The battery protection mode protects the battery.
If the state of charge (SOC) of the battery falls below the thresholds, battery protection mode is activated. In battery protection mode, the Sunny Island switches to energy-saving mode or switches itself off. The battery protection mode has 3 levels. 1 state of charge threshold can be set for each level. Level 1 and 2 of the battery protection mode have specific start and end times and are therefore dependent on the time of day ( > Setting Time-Dependent Functions).
