Abstract
An inverter for converting DC power of a generator into grid-conforming AC power includes an inverter bridge circuit and a scanning circuit configured to trace at least one part of a characteristic curve of the generator to determine an MPP power value (P). The scanning circuit is configured, in the case of a derating to a derated power (P), to trigger a tracing of the characteristic curve with provision of a first power profile deviating from the derated power (P) if an enable signal is present at the inverter, and to indicate a start and an end of the tracing by outputting a start signal and an end signal, respectively. The scanning circuit is further configured to provide a second power profile as AC power upon receiving a start signal, wherein the first power profile has a deviation from the derated power (P) with a sign that is opposite to a sign of a deviation of the second power profile from the derated power (P).
