Implementation and feedback of setpoints for active power limitation when PV
electricity is directly marketed
The PV current generated by your system can be directly marketed. The Cluster Controller can
receive setpoints for active power limitation from the direct marketer as digital or analog signals or
via Modbus. The "CLCON-S-10" model provides a Modbus register for sending setpoints via
Modbus. The model "CLCON-10" provides two Modbus registers.
The Cluster Controller can provide feedback about the current feed-in power of the system to the
direct marketer via digital or analog signals. To avoid conflicts when different setpoints are used by
the grid operator and the direct marketer, the Cluster Controller always implements the setpoint that
more strongly limits the active power of the system.
Sending the system data to an FTP server and/or the Sunny Portal Internet
portal
The Cluster Controller can automatically send the system data that has been read out to an
arbitrary FTP server and/or the Sunny Portal Internet portal via the Internet. The Cluster Controller
establishes the connection to the FTP server and/or Sunny Portal e.g. via a router.
Performing updates for the Cluster Controller and the inverters
You have the option of performing updates for the Cluster Controller and the inverters in the system.
You can perform the updates automatically or manually. The update source can be the
SMA Update Portal or a USB data carrier with update files downloaded from the Internet.
Alternatively, you can also upload the update files directly from the computer via the user interface
of the Cluster Controller.
