Qualified person

Starting the Installation Assistant

Open the user interface ( > Establishing a connection to the user interface).
Log in as Installer.
Start the installation assistant ( > Starting the Installation Assistant).
Select [Save and continue] after each step up until the step Grid management service.
Make the settings as described in the following.

In the tab Active power mode from the drop-down list Connected line conductors, select the line conductor to which the inverter is connected.

Set the Grid connection point regulation to [Off].
In the tab Active power mode set the switch Active power setpoint to [On].
In the drop-down list Operating mode active power setpoint, select the entry External setpoint.
In the drop-down list Fallback behavior, select the entry Apply fallback values.
In the field Fallback value of maximum active power enter the value to which the inverter is to limit its rated power in case of a communication failure to the higher control unit at the end of the timeout time.
In the field Timeout, enter the time that the inverter is to wait before it limits its rated power to the set fallback value.
If, in the event of a 0% or 0 W 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 setting. This ensures that in the event of a 0% or 0 W specification, the inverter disconnects from the utility grid and does not feed in active power.

In the tab Active power mode set the switch Grid connection point regulation to [On].
Enter the total power of the PV modules in the field Nominal PV system power.
In the drop-down list Operating mode of act. power limit. at grid connection pt, select whether active power limitation is to be performed via a fixed specification in percent or in watts.
In the field Set active power limit at grid connection point, enter the value to which the active power at the point of interconnection is to be limited. The value must be set to 0 for zero power output.
Set Active power setpoint to [On].
For the manual preset, in the drop-down list Operating mode active power setting, select Manual setting in % or Manual setting in W and enter the respective default value in the field Active power.
If the inverter itself is to control the active power at the point of interconnection, select External setting in the Operating mode active power setting drop-down list, select Apply fallback values in the Fallback behavior drop-down list, and select No in the Grid disconnection for 0% active power setting drop-down list.
