Country data set for operation with external decoupling protection
When operating the PV system with an external decoupling protection, the inverter with a
firmware version ≤ 2.99.99.R has the country data set Medium-Voltage Directive
(Germany) or MVtgDirective and with a firmware version ≥ 3.00.00.R the country data set
DE VDE-AR-N4110:2018 generator ext. Decoup. Protection Device or
VDEARN4110/18a. These country data sets allow you to extend the operating range of the
inverter for voltage and frequency. These country data sets may only be selected if the PV
system is disconnected via external decoupling.
• If the country data set for operation is set with external decoupling protection, only
operate the inverter with an external three-phase decoupling protection. Without external
three‑phase decoupling protection, the inverter will not disconnect from the utility grid
when the country-specific standard requirement is exceeded.
Country data sets for all EU countries still not included in the firmware
version ≥3.00.00.R
Since the new grid connection regulations have not yet been defined for all EU countries, the
firmware version ≥ 3.00.00.R does not yet contain country data sets for all EU countries. A
generally valid country data set in accordance with EN50549 is included instead. It can be
used in EU countries for which no country data set is available. For individual EU countries,
however, it may be temporarily necessary to make adjustments to the locally valid grid
connection regulations via parameter settings. This is done on the basis of the country data set
previously valid for the country in the firmware version ≤ 2.99.99.R.
• It is decided how to proceed according to the locally valid regulations and the SMA
manufacturer's declaration valid for the country of use. Set the generally valid country
dataset according to EN 50549 with the firmware version ≥ 3.00.00.R or select the
previously valid country dataset with the firmware version ≤ 2.99.99.R. Make the
parameter settings according to the manufacturer's declaration.
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. The change is valid from firmware version
≥3.00.00.R. Names and units of grid parameters for inverters with firmware version
≤2.99.99.R are not affected by this change and remain valid.
