Surge Protection for Photovoltaic Applications Protect Your PV Investment from Damaging Surges The Need for Surge Protection          Modular DIN-rail design with color indication feature makes it easy to identify, install and maintain Built-in fuse protection improves the safety Visual indication and optional remote signaling make status monitoring simple Fast-acting mechanism responds quickly to surge current Modular plug-in design makes the change of modular easy The unique nature of PV installations make them vulnerable to overvoltages and surges from lightning strikes and static discharges. The surges need to be intercepted before they take down the entire system by damaging the PV arrays, charge controller/inverter and distribution boxes. It is vital that surge suppressor elements which are subject to wear, are easily monitored for performance. The BRSA6 PV Surge Suppression systems provide standard visual indication and remote signaling to keep system maintainers informed.
