Rapid Shutdown User Manual SAVE THESE INSTRUCTIONS · This manual contains important instructions for installation and maintenance of the Hoymiles product models HRSD-1C and the Transmitter. · Risk of electric shock, do not remove the cover, disassemble, or repair, no user-serviceable parts inside. If it fails, contact Hoymiles Customer Support. Damaging or opening the product will void the warranty. · Before installing or using the Hoymiles HRSD-1C System, please read all instructions and warning markings on the Hoymiles products, relevant sections of your inverter manual, photovoltaic (PV) module installation manual, and other available safety guides. · Failure to adhere to these instructions may result in injury or death, damage to the system or invalidating the factory warranty. · Perform all electrical installations in accordance with local codes. · Do NOT disconnect the PV module from the HRSD-1C without first disconnecting the AC power. · Installation must be performed by trained professionals only. Hoymiles does not assume liability for loss or damage resulting from improper handling, installation, or misuse of products · Do not attempt to install in inclement weather. · Be aware that the body of the running HRSD-1C is the heat sink and can reach high temperatures. To reduce the risk of burns, do not touch the body of the HRSD-1C. · Do not operate the HRSD-1C if they have been physically damaged. Check existing cables and connectors and ensure they are in good condition and appropriate in rating. Do not operate HRSD1C with damaged or substandard wiring or connectors. · Do not connect or disconnect under load. Turning off the Inverter and/or the HRSD-1C products may not reduce this risk. Internal capacitors within the inverter can remain charged for several minutes after disconnecting all power sources. Verify capacitors have discharged by measuring a voltage across inverter terminals before disconnecting wiring if service is required. Wait 30 seconds after rapid shutdown activation before disconnecting DC cables or turning off DC disconnect. · The transmitter control power supply MUST be on the same AC branch circuit as the inverter to meet rapid shutdown requirements. © 2022 Hoymiles Power Electronics Inc.

Product 1.1 HRSD-1C Features · Meets NEC2017&NEC2020 690.12 requirements · Meets Sunspec RSD requirements · PLC communicationrealize rapid shutdown with Transmitter · Plug & play, no confguration required · Lower power consumption and wider operating voltage range · Much lower than arc noise. No risk of triggering AFCI As part of Hoymiles rapid shutdown solution for PV system, HRSD-1C can be connected with one module. It meets NEC2017, NEC 2020, UL 1741 and Sunspec Rapid Shutdown requirements, guaranteeing PV system safety. When installed with and receiving a "permission to operate" signal from Hoymiles Transmitter, HRSD starts proper operation of PV system. In case of emergency, PV system would enter module-level rapid shutdown mode by simply disconnecting the AC power of Transmitter or using an external initiator. © 2022 Hoymiles Power Electronics Inc. All rights reserved. 01 Rapid Shutdown User Manual 1.2 HT10 Features · Meets NEC2017&NEC2020 690.12 requirements · Meets SunSpec RSD requirements · Equipped with single/dual core · Realize rapid shutdown by simply powering off the transmitter or using an external initiator The Transmitter HT10 is part of Hoymiles Rapid Shutdown solution. When paired with Hoymiles rapid shutdown HRSD and powered on, HT10 sends a "permission to operate" signal to HRSD, to make PV modules connected in series and then connect to string inverter, thus producing power. In case of emergency, PV system would enter module-level rapid shutdown mode by simply disconnecting the AC powerof Transmitter or using an external initiator. © 2022 Hoymiles Power Electronics Inc. All rights reserved. 02 Rapid Shutdown User Manual 1.3 HT10-Kit Features · Meets NEC2017&NEC2020 (690.12) and Sunspec RSD requirements · Module-level rapid shutdown with Hoymiles HRSD · Equipped with single/dual core · Realize rapid shutdown by simply powering off the transmitter or using an external initiator · Weatherproof outdoor enclosure · Includes power supply Hoymiles Transmitter HT10-Kit is part of a rapid shutdown solution when paired with Hoymiles rapid shutdown HRSD. While powered on, HT10-Kit sends a "permission to operate" signal to HRSD to keep the PV modules connected in series to the string inverter and producing power. PV system equipped with HRSD and HT10-Kit enters module-level rapid shutdown by simply disconnecting the AC power of the Transmitterduring emergencies. Hoymiles Transmitter Outdoor Kit includes one Transmitter, one or two cores, 85~264V power supply and outdoor enclosure. © 2022 Hoymiles Power Electronics Inc. All rights reserved. 03 Rapid Shutdown User Manual 2. System Overview ~ ~ The HRSD-1C requires a Transmitter or inverter with built-in transmitter for operation. The Transmitter is installed in line with a solar PV inverter. The HRSD-1C starst in the OFF position and measures 1V at the output. When power is supplied to the Transmitter, the HRSD-1C turns ON and allows full PV module voltage. The HRSD-1C constantly receives a "permission to operate" signal from the Transmitter. When power to the Transmitter is cut, this "permission to operate" signal ceases, sending every HRSD-1C into shutdown mode with output reduced to 1V. In this way, PV array enters rapid shutdown in event of AC grid loss. © 2022 Hoymiles Power Electronics Inc. All rights reserved. 04 Rapid Shutdown User Manual 3. Installation Notes · Installation MUST comply with local regulations and technical rules. · Perform all electrical installations in accordance with local codes. · Be aware that only qualified professionals should install and/or replace the HRSD-1C. · Before installing or using an HRSD-1C, please read all instructions and warnings in the technical documents and on the inverter system itself as well as on the PV array. · Be sure to verify the voltage and current specifications of your PV module match with those of the HRSD-1C. · Never apply an external voltage source to a module or string equipped with HRSD-1C. · HRSD-1C is shipped in the OFF position and will measure 1V at the output when the "permission to operate" signal is not present. · Failing to follow the sequence of installation steps may result in HRSD-1C damage not covered under warranty. · Connect HRSD-1C to its respective modules before connecting its outputs in series. · Install HRSD-1C before powering on the Transmitter. · If parallel string connections are needed, first connect the HRSD-1C to the PV modules, then connect all outputs of HRSD-1C in series, and finally pass one side (+ or -) of the string through the transmitter to turn the system ON. · Do not touch any live parts in the system, including the PV array, when the system has been connected to the electrical grid. · Place rapid shutdown system label no more than 1m (3ft) from initiator (AC disconnect) or service panel containing means of disconnection if not at same location. © 2022 Hoymiles Power Electronics Inc.
