PROBLEM TO BE SOLVED: To provide a method of supplying energy from a photovoltaic power generation module (2) of a photovoltaic power generation system (1) into a supply grid (5) or to a load.SOLUTION: A DC voltage generated by a photovoltaic power generation module (2) is converted to an AC voltage in an inverter (3) having an intermediate circuit (7) having a capacitor and a DC/AC converter (8). In a feed-in mode operation, the inverter (3) is connected to a supply grid (5) or a load through a switching device (4). Input power of the photovoltaic power generation module (2) which is supplied in a test procedure for protecting the switching device (4) is determined in the inverter (3) for implementing the method. When the determined input power of the photovoltaic power generation module (2) is larger than or equal to predetermined minimum input power, the switching device (4) of the inverter (3) is started up. |
