High costs possible due to inappropriate Internet tariffs
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
connected inverters, the frequency of device updates, the frequency of data transfer to
Sunny Portal and the use of FTP push.
