Industry Application

Energy Storage and Solar

DC relays and metering for storage racks fuel cells and solar systems

Storage racks fuel cell systems and solar installations all need a DC contactor that can isolate the source reliably and survive years of cycling. The same sealed high voltage DC relays used in vehicle applications are listed for renewable energy storage fuel battery and solar battery duty.

What Makes This Application Hard

  • A storage rack has to be isolated safely under load for service work
  • Contacts degrade quickly if the arc is not controlled at high DC voltage
  • Cabinet space is shared with the battery modules and power electronics
  • The site needs local indication of DC voltage and current

How These Components Answer It

  • Sealed contacts with permanent magnet arc extinguishing rated to 750VDC
  • Vacuum sealed coil with contacts and coil double isolated
  • Small footprint relative to the current rating
  • Panel voltmeters and ammeters for local indication
