several cables input and one cable output).Applications solar
What power?
Photovoltaic (PV) power renewable energy source converting
sunlight directly into electrical energy using cells. Large PV
systems often consist following main components:
• cells (combined strings, generating the power).).
• Distribution transformer (transforming low voltage high
voltage, grid connection often done high voltage
level).

.
• 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)
