iProduct Description
Rapid shutdown is a device that can achieve string-level fast shutdown in critical situations. The device allows the connection between each photovoltaic module to be switched off remotely or manually, eliminating DC high voltage in the photovoltaic system array, reducing the risk of electric shock and addressing rescue risks.

String-level Rapid shutdown: Within 30 seconds of activation, the device reduces voltage within the boundary range to less than 80V.

Product Features:
✓Suitable for residential, industrial, commercial, and ground power stations.
✓Compatible with 1-10 strings.
✓Design life of 25 years with a 5-year warranty.
✓IP68 waterproof Enclosure box.
✓Triple protection: High-temperature auto-shutdown, AC power cut-off auto-shutdown, and manual shutdown.
