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
