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.
Different IP address ranges required for Speedwire network and LAN
In order for an unambiguous assignment of the IP addresses in the Speedwire network and in
the LAN to be possible from the perspective of the Cluster Controller, 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.
• Ensure that different IP address ranges are used for the Speedwire network and the LAN.
Observe the configuration of the router and the network switch
For the Speedwire connection, the product uses IP addresses from the Unicast range and also
IP addresses from the Multicast range 239/8 (239.0.0.0 to 239.255.255.255).
• When using a router or network switch, ensure that the router and the network switch
forward the Multicast telegrams required for the Speedwire connection to all nodes in the
Speedwire network (for further information on how to configure the router or network
switch, see the manual from the manufacturer).
