4 Product Description
4.1 ClusterController
The ClusterController is a device for monitoring and controlling SMAinverters with Speedwire/
Webconnect interfaces in decentralized PV systems and large-scale PV power plants.
The ClusterController 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 SunnyPortal Internet portal
• Performing updates for the ClusterController and the inverters
Figure 2: Design of the ClusterController

C Keypad
D Display
Reading out, provision and administration of PV system data
The ClusterController 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 ClusterController 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.
Installation ManualClusterController-IA-en-1512

4 Product Description
Configuring device parameters
You can configure specific parameters of individual devices or entire device classes via the user
interface of the ClusterController. You must be logged into the user group Installer on the
ClusterController. 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
(SMAGridGuard parameters) with the approval of the grid operator and using your personal
SMAGridGuard 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
ClusterController 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 ClusterController, 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
ClusterController can implement the setpoints using open-loop control or closed-loop control.
For ClusterController 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
ClusterController 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 ClusterController 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 ClusterController to
configure which setpoints of the ClusterController 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 ClusterController 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 ClusterController 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 ClusterController always implements the setpoint that
more strongly limits the active power of the system.

4 Product Description
SMA Solar Technology AG
Sending the system data to an FTP server and/or the SunnyPortal Internet
portal
The ClusterController can automatically send the system data that has been read out to an
arbitrary FTP server and/or the SunnyPortal Internet portal via the Internet. The ClusterController
establishes the connection to the FTP server and/or SunnyPortal e.g. via a router.
Performing updates for the ClusterController 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
SMAUpdate 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 ClusterController.

5.1 Requirements for Mounting
Requirements for the mounting location:
Product can cause radio interference in living areas
The product is a device of ITE class A (EN55022) and can cause radio interference in living
areas.
• Take suitable measures for shielding radio waves when the ClusterController is used in the
vicinity of living areas.
☐ The mounting location must be indoors.
☐ The ambient conditions at the mounting location must be suitable for the operation of the
ClusterController (see Section9, page78).
☐ The mounting location must be protected against dust, moisture and corrosive substances.
Maximum permitted cable lengths:
☐ Observe the maximum cable length of 100 m each between any two nodes in the Speedwire
network and in the LAN.
☐ When connecting a digital or analog signal source (e.g. remote terminal unit, ripple control
receiver), observe the maximum cable length of 30 m from the ClusterController to the signal
source.
☐ When connecting a temperature sensor using the four-conductor connection technology,
observe the maximum cable length of 20 m from the ClusterController to the temperature
sensor.
☐ When connecting a temperature sensor using the two-conductor connection technology,
observe the maximum cable length of 2.5 m from the ClusterController to the temperature
sensor.
Minimum clearances:
☐ The minimum clearances must be maintained to ensure adequate heat dissipation.
Installation ManualClusterController-IA-en-1522
SMA Solar Technology AG
Figure 7: Minimum clearances
Permitted and prohibited mounting positions:
☐ The ClusterController must be mounted so that the ventilation slots face upward and
downward. This ensures optimum heat dissipation.
5 Mounting
Figure 8: Permitted and prohibited mounting positions
5.2 Mounting the ClusterController
Requirements:
☐ A top-hat rail must be available.
☐ The top-hat rail must 35 mm wide.
Installation Manual 23ClusterController-IA-en-15
5 Mounting
SMA Solar Technology AG
☐ In order to mount the ClusterController, the top-hat rail must be at least 26 cm long. When a
top-hat rail power supply unit is used, the top-hat rail must be correspondingly longer.
☐ The top-hat rail must be securely mounted on the wall or in the switch cabinet.
Procedure:
• Use the rear-side upper retainers to hook the
ClusterController into the upper edge of the tophat rail and press down toward the top-hat rail.
This will hook the spring-mounted top-hat rail
locking mechanism on the ClusterController
onto the lower edge of the top-hat rail.
☑ The top-hat rail locking mechanism snaps into place.
