Photovoltaic power generation plant, supply line for a power plant, mating plug and inverter

摘要

A photovoltaic power generation plant (1) comprising a string (20) comprising a series connection of solar modules (10) electrically connected to an inverter (30) via connecting leads (50) for converting and feeding electrical power to the string (20) , is characterized in that the inverter (30) is adapted to provide an alternative operating power in the event that a normal operating power is obtainable neither from the mains nor from the entire string (20), only from one of the solar modules (10) Respectively. A supply line may supply the alternative operating power to the inverter (30). Furthermore, plugs (90) and mating plugs (100) of such a supply line are described, which can also be installed with an inverter (30).
