  • Patent number: 9929673
    Abstract: A method for feeding energy from photovoltaic modules (2) of a photovoltaic system (1) into a supply grid (5), or to a load, converts the DC voltage (UDC) generated by the photovoltaic modules (2) in an inverter (3) with an intermediate circuit (7) with a capacitor (CZW) and with a DC/AC-converter (8) into an AC voltage (UAC), and in a feed-in mode of operation the inverter (3) is connected via a switching device (4) to the supply grid (5), or to the load, together with an inverter (3) for executing the method. For conservation of the switching device (4) the input power (Pe) of the photovoltaic modules (2) is determined in a test procedure, and the switching device (4) of the inverter (3) is activated if the input power (Pe) of the photovoltaic modules (2) as determined is greater than or equal to a specified minimum input power (Pe,min).
