3.3 Sunny Central Communication Controller
The Sunny Central Communication Controller (SC-COM) is the central communication interface of the inverter.
The SC-COM establishes the connection between the inverter and the operator.
Figure 10: SC-COM
The SC-COM collects all data from the connected devices. The SC-COM enables monitoring, parameterization and
remote diagnosis of the inverter via computer, as well as power control by the grid operator.
These various tasks performed by the SC-COM can be organized in two separate networks:
• Monitoring network
This network is used for monitoring, parameterization and remote diagnosis.
• Control network
This network is used by the Power Plant Controller to specifications issued by the grid operator relating to grid
management services to the inverter. The control network is used exclusively for grid management services which are
thus transmitted and implemented within a specified time period.
If only a low bandwidth is required for monitoring the PV plant, the network operator instructions can also be
transmitted via the monitoring network. In this case, only one network is necessary.
The SC-COM makes all data collected available to the operator via an Ethernet connection.
Copper cables or optical fibers can be used for the networks.
C Red light repeater
The DC Switch is open.
