4 Product Description
4.1 ClusterController
The ClusterController is a device for monitoring and controlling SMAinverters with Speedwire/
Webconnect interfaces in decentralized PV systems and large-scale PV power plants.
The ClusterController primarily performs the following tasks:
• Set-up of the Speedwire network
• Reading out, provision and administration of PV system data
• Configuring device parameters
• Feedback on current total active power of the system
• Implementation and feedback of grid operator setpoints for active power limitation and
reactive power operation under grid management services
• Implementation and feedback of setpoints for active power limitation when PV electricity is
directly marketed
• Sending e-mail alarms in the event of critical system statuses
• Sending the system data to an FTP server and/or the SunnyPortal Internet portal
• Performing updates for the ClusterController and the inverters

D Display
Reading out, provision and administration of PV system data
The ClusterController is the central communication unit for the system and continuously reads out
the data of the devices in the system (e.g. inverters, sensors). The ClusterController then makes this
system data available via the display, user interface and Modbus data interface. In addition, the PV
system data can be displayed, evaluated and managed using Sunny Portal.
4 Product Description SMA Solar Technology AG
Installation ManualClusterController-IA-en-1512

Configuring device parameters
You can configure specific parameters of individual devices or entire device classes via the user
interface of the ClusterController. You must be logged into the user group Installer on the
ClusterController. The device parameters that can be configured, if any, depend on the device and
the rights of the user group. You may only change grid-sensitive device parameters
(SMAGridGuard parameters) with the approval of the grid operator and using your personal
SMAGridGuard code.
Sending e-mail alarms in the event of critical system statuses
You have the option of receiving prompt information on critical system statuses via e-mail. The
ClusterController automatically sends a notification if alarm-related events occur in the system.
Feedback on current total active power of the system
You have the option of being informed of the total active power currently generated by the system
via an analog current output signal.
Implementation and feedback of grid operator setpoints for active power
limitation and reactive power operation under grid management services
With the ClusterController, as part of grid management services you can implement different grid
operator setpoints for active power limitation and reactive power operation of your system. The
ClusterController can implement the setpoints using open-loop control or closed-loop control.
For ClusterController systems without self-consumption and with direct limitation of active power
feed-in, the operating mode Open-loop control is used. In this operating mode, the
ClusterController can receive the setpoints either in the form of digital or analog signals, or via
Modbus. The different types of signal source can be combined so that, for example, the setpoints
for the active power limitation are received as digital signals and the reactive power setpoints are
received as analog signals: For ClusterController systems with self-consumption, the operating
mode Closed-loop control is used. In this operating mode, you can regulate the active power fed
in by the system at the grid-connection point and limit it e.g. to a fixed percentage value. In
agreement with your grid operator, you can use the user interface of the ClusterController to
configure which setpoints of the ClusterController are to be transmitted to the connected inverters
depending on the respective signal. In addition, you can use a digital response contact or an
analog current output signal to inform the grid operator of the setpoints (if any) for active power
limitation and reactive power operation that are currently being used in the system.
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.

Installation Manual 13ClusterController-IA-en-15

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.
