Description
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, feed-in operation ends and the inverter
switches off .
