Brand: Hoymiles

Model: HT10

Type: Installation guide

Hoymiles HT10 is a rapid shutdown system designed to enhance the safety of your solar PV system. It enables you to quickly and safely shut down the system in the event of an emergency, such as a fire or grid failure. The system comprises a transmitter, cores, and a power supply unit. The transmitter communicates with the cores to initiate a rapid shutdown when necessary. The cores are connected to the PV strings and are responsible for interrupting the circuit. The power supply unit provides power to the transmitter and the cores.

Note:

· Install HRSD before powering on Transmitter.

· Transmitter power supply must be on same AC branch circuit as

inverter to meet rapid shutdown requirements.

· When PV system is operating, the Power LED1 should be lit and the

Signal LED2 should be blinking.

· Place rapid shutdown system label no more than 1m (3ft) from

Transmitter or AC disconnect if not at same location.

Note:

· Max. number of strings per Core*: 5 (75A core) or 15 (150A core)

· Max. current per Core: 75A or 150A

· Max. cable length from inverter (+) to inverter (-): 1000ft (300m)

3. Installation

· Mount Transmitter and power supply on DIN rail.

· Connect DC leads from power supply to Transmitter.

· Connect Core to Transmitter. If there is only one core

need to connect, please connect Core 1 first.

Note:

· 85-264VAC or 180-550VAC PSU can be used.

· 180-550VAC PSU isolation class I requires grounding.
