Abstract
A photovoltaic inverter has a DC input for connection to a DC source, a DC-DC converter, an intermediate circuit, a DC-AC converter, an AC disconnector, a control device, an AC connection for connection to a supply network and, if present, a consumer, a battery stage, and a battery connection for connection to a buffer battery, and a method operates a photovoltaic inverter of this kind. A switched-mode power supply is connected on the input side to the AC connection and on the output side to the battery stage so that, if the DC source is deactivated, the intermediate circuit can be charged up to a threshold value via the switched-mode power supply and the battery stage, whereupon the AC disconnector can be actuated and the photovoltaic inverter can be connected to the supply network.
