6.4.3 Communication for Multi-device Connection
To increase its performance, the Sunny Island 5048 can be connected in parallel or in
a 3-phase system with other Sunny Island 5048 devices. The devices communicate with
each other through an RJ45 communication cable.
The RJ45 communication cable is a common 1:1 computer cable.
Each Sunny Island 5048 device is delivered with one black and one white RJ45
communication cable.
You require the black cable to establish (internal) communication between several
Sunny Island 5048 devices. If you only have one Sunny Island 5048 in your
cluster, the cable is not required.
The white cable is used for external communication (via RS232 or RS485), see
also section 6.5 "Interface for External Communication" (Page 51).
Make sure that you have selected a multi-phase/parallel configuration in the
Quick Configuration Guide (see section 8 "(First) Commissioning" (Page 57)).
