Description of the device

3.1

Mode of operation

The device converts the DC voltage generated by the PV modules into AC voltage and feeds it into the 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 requirements
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.
