High costs due to inappropriate Internet tariff
Depending on use, the data volume of the product transferred via the Internet may vary in size.
The data volume depends, for example, on the number of inverters in the system, the frequency
of device updates, the frequency of data transfer to Sunny Portal or the use of FTP push. High
costs for the Internet connection can be the result.
• SMA Solar Technology AG recommends using an Internet flat rate.
Change to the names and units of grid parameters to comply with the grid-
connection requirements in accordance with Regulation (EU) 2016/631
(valid from April 27, 2019)
To comply with the EU grid-connection requirements (valid from April 27, 2019) the names
and units of grid parameters were changed. This change is valid from firmware version
≥ 3.00.00.R if a country data set for fulfilling the EU grid-connection requirements (valid from
2019-04-27) is set. Names and units of grid parameters for inverters with firmware version
≤ 2.99.99.R are not affected by this change and remain valid. This also applies from firmware
version ≥ 3.00.00.R if a country data set that is valid for countries outside the EU is set.
