Configuring the Active Power Mode

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, select the line conductor to which the inverter is connected from the drop-down list Connected line conductors.

Set theGrid 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 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.
In the field Timeout, enter the time that the inverter is to wait before it limits its nominal 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 setpoint. 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 array in the field Nominal system power.
In the drop-down list Operating mode active power setting, 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, 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 active power.
Set the Active power setpoint to [On].
Select the entry Manual setpoint in % or Manual setpoint in W for manual specification and enter the respective setpoint value.
If the inverter itself is to control active power at the point of interconnection, perform the following steps:

In the drop-down list Operating mode active power setting, select the entry External setting.
In the drop-down list Fallback behavior, select the entry Apply fallback values.
In the drop-down list Grid disconnection for active power setpoint of 0% select the entry No.
