Drone EL detector
Model: FT-EL4
It is designed for detecting internal EL defects of photovoltaic power station array modules. It uses the DJI M300RTK drone, which has long endurance, stable flight, and accurate positioning. Equipped with a German high-frequency infrared chip camera, it has clear imaging and accurate focusing, and can switch between photo and video modes for detection. It is equipped with a reliable string-programmable power supply, and has a built-in temperature control system to ensure safety. The software has rich functions, can process videos and pictures, and can also be optionally equipped with cloud management and automatic defect recognition functions.
Portable EL detector
①Model FT-EL1
Defects that can be identified: microcracks, broken wafers, fragments, broken grids, black hearts, poor soldering, process pollution, low-efficiency wafers, black edges, sintering, over-etching, perforation
It focuses on portability. It weighs only 5 kg and is convenient to carry to various inspection sites. It has a 20-megapixel infrared camera with clear imaging, and the automatic full-focus can quickly capture images. The programmable constant current power supply it is equipped with is safe and stable, and has protection functions such as short circuit and overheating. Images can be viewed through tablet computer image transmission, and the operation is convenient. It is suitable for module arrival inspection at power stations, pre-installation testing, and module quality inspection in warehouses and other places.
②Model FT-EL2
Defects that can be identified: the same as FT-EL1
Equipped with a 24-megapixel high-definition infrared camera, it can clearly present the internal quality problems of photovoltaic panels. Full-time automatic focusing ensures imaging accuracy. The energy storage power supply and Wi-Fi wireless control module enable wireless detection and rapid imaging. Using tablet computer wireless image transmission, there is no need to view through the camera. The programmable constant current power supply can conduct uninterrupted testing for 24 hours, and the three-proof trolley case is convenient for transportation. It can be tested in various scenarios, such as module arrival inspection at power stations and module testing on brackets.
③Model FT-EL3
Defects that can be identified: microcracks, broken wafers, fragments, broken grids, black hearts, poor soldering, hot spots, process pollution, low-efficiency wafers, black edges, sintering, over-etching, perforation, PID
The 24-megapixel high-sensitivity infrared camera performs well in the testing of n-type half-cut modules, and the images are clear. The full-time dark-light automatic focusing adapts to various lighting conditions. The multi-module imaging ability can simultaneously complete the imaging of 1 - 2 groups of photovoltaic panels, with fast speed and high image quality. It supports networked wireless control and data viewing and downloading. The large-capacity energy storage power supply allows testing without any preparation. The three-meter carbon fiber tripod is convenient for multi-angle testing, bringing an efficient experience for photovoltaic detection.
