Description of the unit

3.1

Mode of operation

The unit converts the DC voltage generated by the PV-modules into AC voltage and feeds this into the power grid. The
starting procedure begins when there is sufficient sunlight and a specific minimum voltage is present in the device. The
feed-in process begins once the PV generator has passed the insulation test and the grid parameters are within the re-
quirements imposed by the grid operator for a specific monitoring time. If, as it gets dark, the voltage drops below the
minimum voltage value, feed-in mode ends and the device switches off.
