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.
