The invention relates to an electrical circuit arrangement for controlling the output of at least one string of a solar generator, the string comprising: a first mechanical switch (30, 31; 32) to selectively interrupt one (11) of the connecting lines (11, 12) of the string, a measuring device (100-190; 200-230) for measuring the voltage across the string and/or the current flowing through the string, and a controller (60, 61, 63) receiving a signal from the measuring device and controlling the mechanical switch, wherein the controller is adapted to open the mechanical switch if the voltage and/or the current is not within a predetermined range. The invention allows a advanced control of large-scale solar generators to provide more safety and efficiency of such solar generators. |
