Abstract
A method for determining a currently maximum possible power of a photovoltaic (PV) installation operated in a curtailed manner and including a PV generator having at least one string, wherein the at least one string includes a series circuit of PV modules, in which at least one PV module is connected to adjacent PV modules in the string via a coupling circuit. The installation further includes an inverter which is connected, on the output side, to an energy supply grid and is connected, on the input side, to the PV generator. The installation also includes a controller for controlling the inverter and the coupling circuit, wherein the controller, in conjunction with the coupling circuit, is designed to vary a power drain of the PV module assigned to it relative to a power drain of the adjacent PV modules during operation of the PV installation.
