Abstract
A photovoltaic system having an inverter and a photovoltaic generator connected to an inverter input is configured to track an operating voltage of maximum power from the photovoltaic generator. The system also includes an energy store coupled in parallel with the photovoltaic generator, to the input of the inverter. A temporal profile of the power output by the photovoltaic generator is recorded by the converter and compensates for fluctuations in power from the photovoltaic generator in comparison with a target power by adapting the power (P) output by it at the input or branched off from there in such a manner that the sum of the power (P) from the converter and the power (P) from the photovoltaic generator is equal to the target power (P). The converter is operated in a tracking mode that it makes it possible to track the operating voltage of maximum power by means of the inverter. There is a repeated change between the compensation mode and the tracking mode during ongoing operation of the photovoltaic system in which power from the photovoltaic generator is available.
