Procedure:
1. Connect the Cluster Controller to the Speedwire network. Take the desired network topology
into account:
• When using a preassembled network cable, connect the network cable to network port
X9
or
X10
.
• When using a network cable that is to be assembled by the user, connect the RJ45
connector to the network cable (see the manual from manufacturer) and connect the
network cable to network port
X9
or
X10
on the Cluster Controller.
2. Write down the terminal assignment on the supplied supplementary sheet.
3. Deactivate the Webconnect function on the inverters after completion of Cluster Controller
commissioning (see the Cluster Controller user manual).

High costs possible due to inappropriate Internet tariff
Depending on use, the data volume transferred by the Cluster Controller 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 Sunny Portal and the
use of FTP push.
• SMA recommends using an Internet flat rate.
