Abstract

The invention relates to a photovoltaic system comprising a photovoltaic generator (1), which is connected to the DC input of an inverter (3), the AC voltage output of which is connected to a supply network and to at least one consumption point (V). A blocking device (5) prevents a power flow from the photovoltaic generator to the supply network. This measure prevents a power flow from the side of the photovoltaic generator into the supply network and therefore permits easier stabilization of the network voltage against overvoltages.
