Rapid Shutdown Models We carry
The Hoymiles HRSD-1C connects to 1 panel and will stop production of that panel in the event of a fire due to the high voltage DC electricity of string inverters.
The Hoymiles HRSD-2C connects to 2 panels and will stop production of the two panels in the event of a fire due to the high voltage DC electricity of string inverters.
The Hoymiles HT10 is part of the Rapid Shutdown system. The HT10 will send a permission to operate to the string inverter which will allow each panel to continue producing. In the event of a fire, the PV system will enter module-level rapid shutdown mode by disconnecting the AC power.
The Hoymiles HT10-Kit is for outdoor installation situations and is completely weather proof.
