Configuring Feed-In Management


Qualified person

Starting the installation assistant

  1. Activate the user interface Establishing a connection to the user interface).
  2. Log in as Installer.
  3. Start the installation assistant Starting the Installation Assistant).
  4. Select [Save and continue] after each step up until the step Configure grid management service.
  5. Make the settings as described in the following.

Setting the connected line conductors

  • In the tab Feed-in management, select the line conductor to which the inverter is connected from the drop-down list Connected line conductors.

Making settings for systems without a higher unit

  1. Set Feed-in management at the grid-connection point to [On].
  2. Enter the total PV array power in the field Nominal PV system power.
  3. In the drop-down list Operating mode of active power limitation at the grid-connection point, select whether active power limitation is to be performed via a fixed specification in percent or in watts.
  4. In the field Set active power limit at the grid-connection point, enter the value to which the active power at the grid-connection point is to be limited. The value must be set to 0 for zero export.

Making settings for systems with a higher unit

  • Set Feed-in management at the grid-connection point to [Off].

Activating unbalanced load limitation

Depending on the country data set, unbalanced load limitation may have already been set. In this case, check the settings.

  • If there are single-phase PV inverters in the system and unbalanced load limitation is requested, set Unbalanced load limitation to [On] and enter the maximum permissible unbalanced load in the field Maximum unbalanced load.

  • If there are three-phase PV inverters in the system, set Unbalanced load limitation to [Off].

Setting PV inverter feed-in management

  1. Activate the PV inverter user interface.
  2. Log in as Installer.
  3. Start the installation assistant on the PV inverter user interface.
  4. Select [Save and continue] after each step up until the step Configure grid management service.
  5. Ensure that the function System control and power limitation is set to [On].
  6. In the drop-down list Operating mode active power, select the entry Active power limitation P via system control.
  7. In the drop-down list Operating mode for absent system control, select the entry Use fallback setting.
  8. In the field Fallback active power P, enter the same value as the one entered for the battery inverter. Where necessary, convert this value into a percentage. This ensures that in systems with Sunny Home Manager, the correct fallback value will be adopted in the event of a communication breakdown between Sunny Home Manager and inverter.
  9. In the field Timeout, enter the time that the PV inverter is to wait before it limits its nominal power to the set fallback value.
  10. If, in the event of a 0% or 0 W specification, the PV 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 at zero export. 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.
