System for feeding power from DC current generators into the AC network

The system has at least two active inverters (31-38), each characterized by optimal input power and each connected on the input side to at least one DC current generator (21-28) of fluctuating output power, and a measurement device (40). Switching elements (1-15) perform a changeover process that causes separation of at least one current generator from a first inverter and connection of this generator(s) to a second inverter. A controller (40) triggers the changeover process depending on fulfillment of a condition defined by the controller. An Independent claim is also included for a use of the system for producing and converting current in photovoltaic elements.
