Abstract
The disclosure relates to a combiner box including input connections for string lines from a plurality of strings of photovoltaic modules, and output connections for a pair of output lines to an inverter. The combiner box further includes a switching device by means of which the strings are connected to the inverter and which comprises output-side switching contacts and, for each of the strings or for each pair of strings connected in parallel in a fixed manner in the combiner box, at least one separate input-side switching contact, and an overcurrent protection device, which interrupts occurring overcurrents from or to each of the strings or at least from or to each of the pairs of strings connected in parallel in a fixed manner in the combiner box. The switching device includes a switching-contact drive, which is controlled in order to selectively disconnect the strings from the inverter.
