Abstract:
The disclosure relates to a method for connecting a photovoltaic installation to a power supply grid, the photovoltaic installation comprising a photovoltaic generator, a direct voltage intermediate circuit with at least one capacitor, and an inverter. The method including connecting the direct voltage intermediate circuit to the photovoltaic generator and the capacitor is pre-charged to a first voltage. The direct voltage intermediate circuit is then separated from the photovoltaic generator and the capacitor is discharged to or below a second voltage that corresponds to a maximum operating voltage of the inverter. The inverter is then connected to the power supply grid, an inverter bridge of the inverter is clocked, and the direct voltage intermediate circuit is connected to the photovoltaic generator.
