    Efficient conversion guaranteed

    Flame retardant materials designed for rapid shutdown are engineered to significantly reduce the spread of fire and increase safety in various environments.
    These materials are crafted with special chemical properties that enable them to either resist ignition or slow down the burning process when exposed to fire.
    Rapid shutdown aspect implies that these materials are capable of quickly stopping the fire from spreading, either by forming a protective char layer, releasing compounds that inhibit the combustion process, or cooling down the material surface.

    Optimal performance for every module

    ● When firefighter cut off the AC power in the house, the rapid shutdown will disconnect the DC power one time.
    ● Over temperature protection
    ● IP66 aluminum durable enclosure
    ● Plug and Play easy installation
    ● Emergency button for 100% disconnect
    ● 5 Years warranty

    Electric Vehicles (EVs): Rapid shutdown principles can be applied to EV charging stations. In the event of an emergency or when maintenance work needs to be performed on the charging station, a rapid shutdown mechanism can quickly cut off the power supply to the charging cables, ensuring the safety of users and preventing potential electrical hazards.

    Industrial Machinery: In industrial settings, there are often large machines and equipment that run on high-voltage DC power. Implementing rapid shutdown mechanisms in these systems can help protect workers and prevent accidents by quickly shutting down the power supply in emergency situations.

    Battery Storage Systems: Battery storage systems, such as those used in residential or commercial settings, can also benefit from rapid shutdown functionality. In the event of a fire or other emergencies, a rapid shutdown mechanism can disconnect the battery from the rest of the electrical system, reducing the risk of electrical shock or fire.
