A method for minimizing network feedback of a PV park (10) to a power grid connected to a grid connection point, the PV park (10) having a plurality of inverters (1-8) divided into groups (12, 13), comprising: - for at least one first inverter (2, 3, 7) of each group (12, 13) determining a first parameter representative of a first coupling impedance (Z, Z, Z) between the first inverter (2, 3, 7) and Netzanschlusspunkt is and determining a second parameter representative of a second coupling impedance (Z, Z, Z) between the first inverter (2, 3, 7) containing group (12, 13) and the network connection point, - storing the first and of the second parameter in an operation control unit of the first inverter (2, 3, 7), - in a daytime operation of the PV park (10) feeding reactive power through the first inverter (2, 3, 7) in response to the first parameter, the Corresponds to a reactive power consumed by the respective underlying first coupling impedance (Z, Z, Z), and-in a night mode deactivating all the inverters of a group (12, 13) except the first inverter (2, 3, 7) and feeding Reactive power by the first inverter (2, 3, 7) in response to the second parameter, wherein the reactive power fed corresponds to the extent of a reactive power received by the respective underlying second coupling impedance (Z, Z, Z).
