The invention relates to a method for connecting a photovoltaic installation to a power supply grid (8), the photovoltaic installation comprising a photovoltaic generator (1), a direct voltage intermediate circuit with at least one capacitor (3), and an inverter (5). The method has the following steps, not necessarily in that order: The direct voltage intermediate circuit is connected to the photovoltaic generator (1) and the capacitor (3) is pre-charged to a first voltage (U1) The direct voltage intermediate circuit is then separated from the photovoltaic generator (1) and the capacitor (3) is discharged to or below a second voltage (U2) which corresponds to a maximum operating voltage of the inverter (5). The inverter (5) is then connected to the power supply grid (8), the inverter (5) is started, and the direct voltage intermediate circuit is connected to the photovoltaic generator (1).
