). • Distribution transformer (transforming low voltage high voltage, grid connection often done high voltage level).Applications solar What power? Photovoltaic (PV) power renewable energy source converting sunlight directly into electrical energy using cells. • Trackers (mechanical structure move the angle cells to follow the sun, increasing system efficiency, also including motors, PLC, communication, protection). • Inverter (one several, converting the generated voltage into 50Hz 60Hz, also including devices for switching, protection and control). Large PV systems often consist following main components: • cells (combined strings, generating the power). • Combiners (junction boxes, including switching devices, with several cables input and one cable output). 4 switching contactors 1SFC101004B0201 . • Switching devices and protection devices (to change PV string configuration, protect from over currents, surge voltages and earth faults etc
