Abstract

See full text

A photovoltaic generator is provided that has at least one string of multiple series-connected photovoltaic modules, each of which has a plurality of series-connected photovoltaic cells. One quarter to one half of all photovoltaic modules of the at least one string can be short-circuited by means of a switch. Activation of the switch takes place when a predefined voltage value across the string is exceeded. The shorting switch is only present in some of the arrays making up the photovoltaic generator, which reduces cabling costs. Because of the parallel connection of the arrays, the voltage of the arrays without shorting switches is drawn down to a lower voltage that is safe for the inverter.
