Setting phase-exact zero feed-in

Qualified person

To set the phase-exact zero feed-in, the corresponding parameters must be set in the subordinate inverters and the system.

With phase-exact zero export, the grid feed-in is individually monitored on all three grid conductors. As soon as grid feed-in still occurs on a line conductor, the total feed-in power is reduced. This procedure is mandatory in some countries and may lead to increased grid-supplied power.

Requirements:

  • The user interface must be open and you must be logged in as Installer.
  • The parameter External active power setting, limitation of change rate must be disabled in the subordinate inverter.
  • The parameter External active power setting 2, limitation of change rate must be disabled in the subordinate inverter.
  • The parameter External active power setting, nominal value filter must be disabled in the subordinate inverter.
  • The parameter External active power setting 2, nominal value filter must be disabled in the subordinate inverter.
  • Optimized closed-loop/open-loop control must be activated under Operating mode for active power ( > Configuring active and reactive power setpoints).

    Procedure:

    1. Select the system in the focus navigation.
    2. Select the menu Configuration.
    3. Select the menu item Grid management services.
    4. Select Configuration & activation under Active and reactive power.
    5. Open the sub-item Grid operator specifications in the Active power area.
    6. Activate Manual setpoint for active power limitation.
    7. Activate the button Phase-exact zero active power feed-in.
    8. Click on [Save].
