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