Connecting the Cluster Controller to a Speedwire Network
Do not connect the Speedwire network and the local area network (LAN)
The Speedwire network is a separate network managed by the Cluster Controller. If the Speedwire
network and the local area network (LAN) are connected, a disturbance of both networks is likely to
occur.
• In order to ensure correct communication, do not connect the Speedwire network and the local
area network (LAN). The Speedwire bus and the Ethernet bus must not be connected to the same
switch.
Observe the configuration of the router and the network switch
For the Speedwire connection, the Cluster Controller uses IP addresses from the Unicast area and also
IP addresses from the Multicast area 239/8 (239.0.0.0 to 239.255.255.255).
• When using a router or network switch, ensure that the router and switch forward the Multicast
telegrams required for the Speedwire connection to all nodes of the Speedwire network
(for information on configuration of the router or switch, see the manufacturer manual).
Requirements:
☐ The nodes in the Speedwire network (e. g. inverters) must be cabled in accordance with one of the possible
network topologies (see the node installation manual and the Technical Information "SMA Speedwire
Fieldbus").
Additionally required material (not included in the scope of delivery):
☐ Depending on the network topology: network cable (see Section Cable Requirements).
Procedure:
• Connect the network cable to the network port X9 or X10 of the Cluster Controller.
Connecting the Cluster Controller to the Local Area Network
/05*$&
High costs possible through inappropriate Internet rates
Depending on use, the data volume of the Cluster Controller transferred via the Internet can be more than 1
GB per month. The data volume depends, among other things, on the number of inverters, the frequency of
device updates, the frequency of data transfer to the Sunny Portal and the use of FTP push.
•SMA recommends using an Internet flat rate.

Connecting USB Data Carriers to the Cluster Controller
Not possible to use USB hubs
The Cluster Controller does not support any USB hubs. You must connect the USB data carrier directly
to the desired USB terminal on the Cluster Controller.
Additionally required material (not included in the scope of delivery):
☐ Up to two USB data carriers, e.g. two USB sticks (available as an accessory). If the USB data carrier available as
an accessory is not used, observe the requirements for USB data carriers (see installation manual on the CD
included in the scope of delivery).
Procedure:
1. Connect the USB data carrier to the desired USB terminal of the Cluster Controller.
• To export system data, connect the USB data carrier to the USB terminal 1.
• To transmit update files to the Cluster Controller, connect the USB data carrier to USB terminal 2.
2. If the USB data carrier is to be removed from the Cluster Controller, wait until the data carrier status LED ( ) is
not flashing anymore.
Checking the Connections via the Display
• You can use the display of the Cluster Controller to check whether the connections have been made correctly and
whether all inverters, sensors and remote terminals have been recorded by the
Cluster Controller (see installation manual on the CD included in the scope of delivery).
6 CONFIGURING THE CLUSTER CONTROLLER
Requirement:
☐ The Cluster Controller and the computer must be located in the same local area network (LAN).
Procedure:
1. Log
into the Cluster Controller:
• Select the External Communication display view and read out the IP address of the Cluster Controller.
• Enter the IP address in the address bar of the web browser.

2. Deactivate the Webconnect function of the inverters (see user manua l of the Cl uste r Cont roller on the CD included
in the scope of delivery).
3. Make further desired configurations via the user interface (see user manual on the CD included in the scope of
delivery).
Different IP address ranges required for Speedwire network and local network (LAN)
In order to clearly assign the IP addresses in the Speedwire network and in the local network (LAN) from
the perspective of the Cluster Controller to be possible, the IP address ranges of both networks must be
different. By default, the Cluster Controller uses address range 172.22/16 (172.22.0.1 to
172.22.255.255) for the Speedwire network.
• Make sure that different IP address ranges are used for the Speedwire network and the local
network (LAN).
Additionally required material (not included in the scope of delivery):
☐ 1 network cable (see Section Cable Requirements)
Procedure:
1. Connect the network cable to the network port X13 or X14 of the Cluster Controller.
