Abstract: A method for acquiring a characteristic curve of a PV generator is disclosed. In a power generation installation, an output side of each PV generator is connected via an assigned DC-DC converter, in parallel to a DC link as the input element of a DC-AC converter. The method includes reducing a cumulative output power of those DC-DC converters for which the associated PV generators are not intended for acquiring the characteristic curve during the acquisition of the characteristic curve of the PV generator to be scanned to ensure that the sum of the reduced cumulative output power and of the expected maximum power of the PV generator to be scanned does not exceed a nominal power of the DC-AC converter, and subsequently acquiring the characteristic curve of the PV generator to be scanned.
