Abstract

The invention relates to circuit arrangements for reducing potential-induced degradation in photovoltaic modules of a photovoltaic generator, said circuit arrangements comprising an insulation monitoring device for a temporally continuous insulation monitoring of the photovoltaic generator. Furthermore, the invention relates to a photovoltaic system comprising a circuit arrangement for reducing potential-induced degradation in photovoltaic modules, said photovoltaic system comprising a photovoltaic generator and an insulation monitoring device for a temporally continuous insulation monitoring of the photovoltaic generator. Different solutions are proposed which enable reducing potential-induced degradation while simultaneously continuously monitoring insulations. The circuit arrangements according to the invention rest upon an insulation monitoring device interacting with measures based circuit technology for influencing potentials in a photovoltaic module.
