How it works

The inverter converts the DC voltage generated by the PV modules into AC voltage and leads this into the grid feed-
in. The feed-in process begins when there is suffi

cient irradiance and a specifi c minimum voltage is present in the

inverter. If, as nightfall approaches, the voltage drops below the minimum voltage value, feed-in mode ends and
the inverter switches off .
