• 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. -
Page 7: System Overview
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”... -
Page 8: Installation Notes
• 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. -
