Connecting Control and Measuring Cables of the Multicluster-Box

Qualified person

For a multicluster system, the Multicluster-Box communicates control and measuring data with the three Sunny Island inverters of the main cluster via three red data cables (see Multicluster-Box documentation). The red data cables are part of the scope of delivery of the Multicluster-Box.

Cable requirements:

  • Cable length for BatVtgOut, DigIn and BatTemp: less than 30 m

Procedure:

  1. Plug the red data cables into the pin connector BackupVtgCur on the Sunny Island units of the main cluster ( > Connecting the Data Cable). Connect the master with the connection Mstr./L1, slave 1 with the connection Slv1./L2 and slave 2 with the connection Slv2./L3 on the Multicluster-Box.
