SDEV Charger

In the event of a fire, the DC side of a solar array continues to generate high voltage as long as there is light. This presents a significant danger to firefighters, who often cannot safely approach the scene. Ensuring personal safety and providing a way for non-professionals to cut off risks immediately is a primary concern in the photovoltaic industry.
Our Rapid Shut-down Switch is designed to address these market demands. While string inverters have integrated DC isolators for maintenance, they do not de-energize the DC lines from the roof to the inverter (600~1500V). Our firefighter safety switch detects grid failure and automatically turns off the isolation switch after 5 seconds, ensuring a safe environment for emergency responders.
