•Three LAN interfaces

•RS485 interface for communication with devices used for string-current monitoring

•Interfaces for the communication with internal inverter components

These SC-COM interfaces are wired during production. When installing the Sunny Central, connect the external data cables to the customer connection terminals in the Sunny Central.

3.2 Network Concept

In order to transmit the data faster and more efficiently, the SC-COM is equipped with two additional LAN interfaces. This enables two separate networks to be created as required. Due to the two separate networks, a faster rate of data communication with extremely short response times is achieved. If your network has sufficient data transmission speed, one network may be sufficient for both types of data.

Control Network LAN2

In the control network, the specifications of the network operator for grid management, such as target values for active and reactive power, are transmitted. The SC-COM transmits these specifications to the Sunny Central.
