PROJOY RSD Solution Improving Solar Building Safety

As a leading manufacturer of PV safety products in China, PROJOY offers a full rapid shutdown solution to deliver unmatched safety, simplicity and efficiency for solar installations, including String-level Firefighter Safety Switch (PEFS-EL series) and DC24V Module-level Rapid Shutdown (PEFS-PL Series). 

Unlike conventional solutions, PROJOY Module-level RSD activates via grid-powered supply, eliminating dependency on PV module operation. As long as the grid is energized, the RSD remains ready for immediate deployment. It can reduce the voltage in the array to the safe level (below 80V) within 30 seconds. With built-in temperature sensor, the device can immediately take actions when the temperature exceeds 85°C, automatically shut down and cut off the DC power. Thus, it is crucial to have such device installed to solar panels for public places. 

Seamlessly integrates with all mainstream inverters, our RSD ensures adaptability across diverse PV system configurations without retrofitting and create a safe rescue environment for firefighters, reduce fire losses, and ensure the safety of people and property.

PROJOY Rapid Shutdown solution has gradually became popular in European countries such as Germany and UK, as well as Southeast Asian countries like Thailand and the Philippines. Today, the company is a first-tier brand in Europe and Asia-pacific markets.
