  • Page 10 • Achieves rapid shutdown through Transmitter power-off or external initiation As part of Hoymiles Rapid Shutdown solution, Hoymiles Transmitter HT10 works with HRSD for module- level rapid shutdown. When powered on, the HT10 uses PLC technology to continuously send a “permission to operate” signal to HRSD, enabling the PV system to start producing power.

    Inverter IMPORTANCE • Hoymiles recommends that the Transmitter power supply be on the same AC branch circuit as the inverter to meet rapid shutdown requirements. When energized, the Transmitter constantly sends a “permission to operate” signal to the HRSD-1C, which receives the signal and turns ON and allows full PV module voltage.

  • Page 14: Initiation Methods

    The figures above are intended for working principle illustration only. They do not serve as wiring references. 3.2 Initiation Methods Hoymiles Rapid Shutdown System can be initiated in two ways—1) turning off the AC breaker and 2) pressing the external emergency stop button.
  • Page 15 Serially connect the NC contacts (1 and 2) of the emergency stop button to the live wire (L) of the upstream AC cable. NOTICE The AC circuit should be 220V 6A or 380V 4A. • • The emergency stop button should be installed at an accessible location. © 2024 Hoymiles Power Electronics Inc. All rights reserved.
