Rapid shutdown

Block diagram


Integrating solar rapid shutdown modules into solar systems reduces shock hazards when accessing panels is required. Our integrated circuits and reference designs help you achieve compliance with NEC 2017 section 690.12 and accelerate the development of solar rapid shutdown modules, while improving response time by providing real-time communication and monitoring.

Design requirements

Solar rapid shutdown modules often require:

  • Total system shutdown within 10 seconds of initiation.
  • Accurate monitoring of conductor voltages.
  • Real-time communication and monitoring.
  • Long system lifespan and reliability.
