• Continuously higher legislative demands increasing the share green energy.What the future power? Solar energy today the fastest growing segment renewable energy and believed one the major energy sources in the future. Factors that vouch for bright future solar energy: • Growing climate awareness brings more focus renewable energy. Why contactors needed? PV plants contain some major application for it­ ching, since the electricity produced the panels DC. increase plant efficiency diverting one several strings opti­ mal number converters low output. Contactors are typically selected for app­ lications with the need for remote control and switching least once per day. • Intense research and development the technology in order make more efficient and easier produce.g. Decreased production costs due higher volumes and improved production technique make possible pro­ duce low cost cells which turn will expand the market. Applications Main applications where contactors are used for switching are: • Disconnection the inverter from the strings when the output too low. This makes it possible constantly optimize the efficiency the system. • Changing the string configuration, e. ■ ' PV strings \ \ \ \ 1 ry V DC Block con tactor type AF Bar con tactor R series B lock con tactor type AF v ~ AC G rid side 1SFC101004B0201 switching contactors.
