摘要： A method for determining a maximum power point (MPP) of a photovoltaic generator (PV) by variation of at least one parameter of search voltage and search current, within a maximally searchable search area on a power/voltage curve is disclosed. The method includes initializing by defining a start point with a start voltage and a start current, searching for the maximum power point (MPP) in at least one search direction by repeated variation of the search voltage or search current in the search area taking account of at least two limiting conditions for limiting the search area, wherein at least one of the limiting conditions for limiting the search area are is determined with evaluation of parameters provided in an operating state already attained during the search, and ending the search if one of the at least two limiting conditions for limiting the search area is met.

摘要： A method of matching the power of a photovoltaic system producing electric energy by which a working point at which the system produces maximum power is set by changing the working point in an MPP matching process and by comparing the system power, which changes as a result thereof, is intended to be suited both for stationary characteristic curves and for non stationary generator characteristic curves and to be easy to carry out so that the best working point is always set, even when the system is subjected to external interfering factors. This is achieved in that one or several additional control steps or control cycles are performed in order to track during the matching process a power point changing under external impact for a working point of even higher power to be set.

摘要： A method of activating a Multi-String inverter for photovoltaic generators (1a, 1b) of a photovoltaic plant (6), the Multi-String inverter incorporating on the input side a separate DC-DC converter (2a, 2b) for each generator string (photovoltaic generator) (1a, 1b) and each output of the DC-DC converters (2a, 2b) being connected in parallel and to an input of a DC-AC converter (3) and the DC-AC converter (3) being connected with an alternating current mains (4) for feeding into the mains aims at improving efficiency. This is achieved in that one or several electrical variables, namely input current, input voltage and/or input power are measured at each DC-DC converter (2a, 2b) and at least one of the DC-DC converters (2a, 2b) changing its operating condition as a function of this measurement when a limit value and/or a range is exceeded in such a manner that its power loss is reduced so that the energy yield of the photovoltaic plant (6) is increased.

Based on the analysis a failure of an individual string is ascertained.
