Questions Regarding Multicluster Systems
Extension clusters remain in standby or energy-saving mode even though the main cluster is in inverter mode?
The data cable between the masters of the individual clusters might not be connected. The master of the main cluster cannot forward the "Start" command to the masters of the extension clusters.
Why is the multicluster system not supplying full power?
An extension cluster or individual Sunny Island inverters of an extension cluster might have failed.
Why are high levels of energy being transferred between the clusters in the multicluster system?
The state of charge of the batteries might differ temporarily. The off-grid system equalizes different states of charge automatically.
The nominal frequencies and nominal voltages may be defined differently.
Select Device > Inverter and set the parameters Inverter nominal voltage and Inverter nominal frequency to the same value for all masters.
The battery capacities might differ significantly.
Distribute the battery capacities to the clusters as evenly as possible.
Individual battery cells of a battery might have failed.
Disconnect defective battery cells and set the new rated voltage and capacity ( > Replacing the Battery).
