Portable PV EL/PL Detector

The CHNSpec Technology EP-D/EP-N series is the latest generation of portable EL/PL detection equipment designed for the photovoltaic industry. It includes multiple models such as the EP-D-130/300/500 and EP-N-2000/2500/4800, featuring core advantages of full-scenario adaptability and high efficiency with intelligence, fully meeting various detection needs for photovoltaic panels.

• Unrestricted full-scenario detection: Equipped with three core functions — daytime EL, daytime PL, and nighttime EL. Unaffected by ambient light such as sunlight, artificial light, moonlight, or starlight, enabling "all-weather" operation during the day, under lights, at night, and even in rainy weather. Delivers stable and clear imaging results in complex outdoor scenarios.

• Compatible with module and string measurement

• Built-in AI large model algorithm for automatic identification of defects such as cracks, micro-cracks, broken grids, fragments, and short circuits.

• Lightweight, compact, and easy to operate; can be fully controlled via a tablet.

• Utilizes an advanced hyperspectral imaging system for richer and clearer detection details.
