This product acts on the switching device at the component level and defaults to the off state. When receiving the transmitted signal of the incoming controller, the component string channel is opened and the inverter operates normally; When the transmit signal is not received, the MOSFET is quickly turned off, and the component string channel is also closed, so that the system’s high voltage is reduced to less than 30V within 30s to ensure the safety of fire fighting and installation and maintenance personnel.
