The grid-connected PV System is mainly composed of 4 parts: the
PV-panels, the PV-Inverter, the AC-Connection Unit (the connection
Interface) and a connection to the Public Grid.
When a PV-panel is exposed to sunlight and connected to an inverter,
it generates DC power. The PV-Inverter converts DC to AC and feeds in
to the Public Grid via the AC-Connection unit.
