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.
The basic procedure for changing operating parameters is explained in another section (see
Section8.10 "Changing Operating Parameters", page61).
Procedure:
• In the parameter group Grid monitoring > Grid monitoring select the parameter Set
country standard and set the required country data set.
8.12 Configuring the Active Power Mode
Starting the installation assistant
1. Open the user interface (see Section8.1, page49).
2. Log in as Installer.
3. Start the installation assistant (see Section8.5, page58).
4. Select [Save and continue] after each step up until the step Grid management service.
5. Make the settings as described in the following.
Make the settings for systems with external setpoint
1. Set theGrid connection point regulation to [Off].
2. In the tab Active power mode set the switch Active power setpoint to [On].
3. In the drop-down list Operating mode active power setpoint, select the entry External
setpoint.
4. In the drop-down list Fallback behavior, select the entry Apply fallback values.
5. In the field Fallback value of the maximum active power enter the value to which the
inverter is to limit its nominal power in case of a communication failure to the higher control
unit at the end of the timeout time.
6. In the field Timeout, enter the time that the inverter is to wait before it limits its nominal power
to the set fallback value.
7. If, in the event of a 0% or 0W specification, the inverter is not permitted to feed small amounts
of active power into the utility grid, select the entry Yes in the drop-down list Grid
disconnection for 0% active power setpoint. This ensures that in the event of a 0% or 0W
specification, the inverter disconnects from the utility grid and does not feed in active power.
