3.1 Mode of Operation
The inverter converts the DC voltage generated by the PV modules into AC voltage and feeds it into the grid. The feed-
in process begins when there is suffi
cient sunlight and a specifi c minimum voltage is present in the inverter. If, as it gets
dark, the voltage drops below the minimum voltage value, the feed-in operation ends and the inverter switches off .
