What Is a Safety Switch?
A Safety Switch is an emergency DC disconnect device installed between photovoltaic modules and the inverter. During maintenance, system failure, or emergency situations, it quickly isolates the DC circuit, allowing firefighters and maintenance personnel to work more safely while reducing the risk of electrical hazards.
It is widely used in residential, commercial, and industrial photovoltaic systems where reliable emergency shutdown is required.
