The FS-EP series is the latest generation of portable testing
equipment launched by CHNSpec for EL/PL inspection in the
photovoltaic industry, including the FS-EP-270 / 250 / 230 models. - Equipped with three core functions: daytime EL, daytime PL, and
nighttime EL
- Compatible with both module and string measurements
- Can be tested during daytime, nighttime, and rainy or cloudy
conditions, truly achieving “all-weather” operation
- Adopts an advanced hyperspectral imaging system, providing richer
and clearer detection details
- Built-in artificial intelligence large-model algorithms for
automatic identification of defects such as cracks, microcracks,
broken grid lines, fragments, and short circuits
- Jointly developed by Zhejiang University and China Jiliang
University
- Lightweight, compact, and easy to operate; all operations can be
completed via a tablet computer
