Recently, PROJOY Electric PLC module-level rapid shutdown passed UL 1741 standard test, the United States UL certification. After the DC24V type passed UL certification last year. Another power line communication (PLC) type module-level rapid shutdown has also received a pass to enter the North American market.

UL1741 certification is currently the main evaluation standard for PV Rapid Shutdown System Equipment and PV Rapid Shutdown Systems. To improve the reliability of these safety systems, UL1741 is tested under harsh conditions including hardware failures, software failures, and evaluated under environmental and electrical extremes.

The United States has always implemented the most stringent standards for the safety of photovoltaic power stations. Passing the UL standard test of the United States is a full affirmation of the rapid shutdown products of PROJOY Electric. It is reported that there are only 3 companies in the world whose PLC rapid shutdown is UL certified, and PROJOY PEFS series rapid shutdown is one of them.

In the event of a fire, rooftop photovoltaic (PV) systems present a health and safety hazard for firefighters who may need to access the roof because there could still be between 600 to 1500 VDC running between the inverter and the solar panels.

Projoy Electric's PEFS EL Series of string level rapid shutdown devices (RSD) ensures the safety of firefighters and minimizes further damage to the PV system by automatically shutting down power from the solar panel strings to the inverter when it detects AC shutoff or when the temperature around the RSD exceeds 70 degrees celsius.

Projoy Electric's PEFS-EL40H-10 Commercial-grade string level RSD can control 5 strings of solar panels from 20A to 40A and from 300V to 1500V depending on the installation design.

Please message us for further information and to allow us to recommend the most ideal model for your PV installation.
