Our Products

1. PROJOY PEFS-PL Series Rapid Shutdown / RSD— PEFS-PL Series

We all know that as long as there is radiation on the panel, a voltage of 600~1500Vdc will be generated on the DC side. Even the DC isolator is integrated into the solar inverters, but even when the DC isolator is turned off, there will still be up to 600~1500Vdc between the inverter and the PV panels.

If fire happens in installation without firefighter safety switch, the high voltage DC current inside the panel array or between the panel array and the inverter will threaten the personal safety of firefighters. 

PEFS-PL series rapid shutdown, each fast shutdown can serve 1 or 2 panels. Relying on built-in temperature sensor, it can automatically disconnect the equipment when the temperature exceeds 85℃. With Projoy's PEFS-PL rapid shutdown installed in PV system, each panel will be in open circuit state, and the voltage between panels will be lower than 80V or customized voltage level. The new generation PEFS-PL series which is now in development can monitor and optimize the power generation data of each panel in real time. In the event of an emergency, the panels can be quickly disconnected through the AC switch or fast shutdown button.
