Rapid shutdown is a device that can achieve string-level fast shutdown when 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 the risk of rescue.
String-level Rapid shutdown: Within 30S of the quick shutdown start-up, it reduces voltage within the boundary range to less than 80V.
