Hoymiles HT10 Installation guide

Brand: Hoymiles

Model: HT10

Type: Installation guide

Hoymiles HT10 is a rapid shutdown system that allows for the safe and efficient isolation of solar panels in the event of an emergency. It features two cores, each capable of handling up to 75A or 150A of current, allowing for a maximum of 15 strings per core. The HT10 is designed for use with Hoymiles inverters and requires a Din Rail PSU for power. It ensures compliance with rapid shutdown requirements by powering off the PV system when necessary. The Power LED1 indicates when the system is operating, while the Signal LED2 blinks to show communication.

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 the same location.
