3.3 Sunny Central Communication Controller
The Sunny Central Communication Controller (SC-COM) is the central communication interface of the Sunny Central.
The SC-COM establishes the connection between the Sunny Central and the PV system operator.
Figure 4: SC-COM
The SC-COM collects all data from the connected devices. The SC-COM enables monitoring, parameterization and
remote diagnosis of the Sunny Central via computer, as well as power control by the grid operator.
The various tasks performed by the SC-COM can be split into two separate networks:
•
Monitoring network
This network is used for monitoring, parameterization and remote diagnosis.
•
Control network
This network is used by the Power Reducer Box or Power Plant Controller to transmit grid management specifications
issued by the grid operator to the Sunny Central. The use of the control network exclusively for grid management
services ensures that the setpoints will always be transmitted and implemented within the specified time period.
If only a low data transfer rate is required for monitoring the PV system, the grid operator instructions can also be
transmitted via the monitoring network. In this case, only one network is required.
The SC-COM makes all the collected data available to the PV system operator via an Ethernet connection.
Copper cables or optical fibers can be used for the networks.
