Multicluster Operation SMA Solar Technology AG
126 SI5048-TEN093630 Technical Description
Each Multicluster Piggy-Back (MC-PB) is delivered with one yellow and one gray RJ45 communication
cable and two plugs (termination resistors).
You require the yellow cable to establish communication between the master of the main cluster and
the masters of the extension clusters.
The gray cable is used for external communication (via RS485) needed for the system monitoring
(Sunny WebBox).
RJ45 Cable
The RJ45 communication cable is a standard Cat5e-FTP cable (simple shielding), with gold
contacts.
Multicluster Piggy-Back
If just one cluster is used in connection with an MC-BOX, no Multicluster Piggy-Back is
required.
