Photovoltaic power plants operate outdoors for a long time, and problems such as component obstruction, bird droppings and dust accumulation, hidden cracks in battery cells, virtual soldering in junction boxes, and diode failure can easily cause hot spot effects. Electrical equipment such as combiner boxes, inverters, cable joints, and distribution cabinets can also experience abnormal temperature rises due to poor contact and overload operation. The naked eye cannot recognize subtle temperature differences, and the continuous accumulation of early small thermal hazards can cause significant power attenuation and accelerated aging of components. In severe cases, solder joints can melt and glass can catch fire, leading to major safety accidents in power plants. Traditional manual inspections rely on touch and experience to determine temperature anomalies, resulting in frequent omissions and misjudgments. By the time faults appear, they often cause significant power generation losses. Infrared thermal imaging technology, as a core preventive maintenance method, can capture the temperature distribution of equipment in a non-contact manner and identify early temperature rise hazards in advance. However, traditional industrial thermal imagers have shortcomings such as bulky body, insufficient temperature measurement accuracy, lack of photovoltaic specific algorithms, short battery life, and complex operation, which are difficult to adapt to the high-frequency outdoor inspection needs of photovoltaics. Suzhou Laikesi LAILX is deeply involved in the field of photovoltaic operation and maintenance testing, and has launched the LX-F100 handheld infrared thermal imaging device, which is specially customized and developed for the photovoltaic industry. With ultra-high thermal sensitivity, dual range temperature measurement, AI photovoltaic fault recognition, lightweight handheld body, and all-weather protection design, it has become a standard inspection equipment for identifying thermal hazards in photovoltaic components and electrical equipment. High sensitivity and clear imaging

The LX-F100 is equipped with a high-performance uncooled infrared detector, with a system thermal sensitivity NETD as low as 30mK, which can accurately capture small temperature differences of 0.03 ℃, clearly distinguish between normal areas of photovoltaic modules and early thermal spots, and prevent small hidden dangers from being missed. The temperature measurement range is set with dual intelligent switching range, and the low-temperature mode covers -20 ℃ to 120 ℃, suitable for daily inspection of photovoltaic modules, brackets, and solar panels; The high temperature mode ranges from 0 ℃ to 650 ℃, meeting the high temperature fault detection requirements of electrical equipment such as inverters, distribution cabinets, cable joints, transformers, etc. It covers the temperature monitoring needs of photovoltaic power plants from components to transmission and distribution systems in all scenarios. The temperature measurement accuracy is stably controlled at ± 2 ℃ or ± 2% reading (whichever is larger), fully complying with the industry standard for temperature detection of photovoltaic equipment. The equipment is equipped with professional photovoltaic optical lenses, a wide-angle field of view suitable for rapid scanning of large area arrays, and a long-distance telephoto mode that can accurately observe high supports and distant components on rooftops, without the need for close range climbing, reducing the safety risks of high-altitude operations; Equipped with 4x digital super-resolution enhancement technology, the details are clear after zooming in on the image, and the fine high-temperature points of the wiring terminals and battery cells are fully displayed without the need for additional lens replacement. One device can handle both large-scale inspection and precise temperature measurement.

The lightweight handheld design of the whole machine directly targets the pain points of outdoor inspection. The LX-F100 single host weighs only 580g and has an ergonomic anti slip handle. It is not easy to fatigue during long-term outdoor handheld inspection, and can complete all operations such as shooting, temperature measurement, and image storage with one hand. The body is equipped with a 3.5-inch high-definition touch display screen, which synchronously displays infrared thermal images and visible light reality images. The picture in picture mode allows for quick comparison and precise positioning of the actual device location corresponding to high-temperature points; Support three measurement modes: point temperature measurement, line temperature measurement, and regional temperature difference analysis. Automatically label the highest temperature, lowest temperature, and average temperature values, visualize temperature difference data in real-time, and enable operation and maintenance personnel to identify abnormal areas at a glance. The device is equipped with a photovoltaic exclusive AI fault recognition algorithm, which automatically marks and alarms four typical photovoltaic faults: hot spots, junction box overheating, cable joint temperature rise, and bracket leakage and heating. The screen pops up text prompts the fault type. Zero based operation and maintenance personnel can quickly determine the level of hidden dangers without professional thermal imaging knowledge, distinguish between minor loss faults and high-risk fire hazards, and optimize inspection and disposal priorities.

The outdoor all-weather operation capability fully adapts to the complex photovoltaic field environment. The body adopts a high-strength wear-resistant industrial shell with IP54 dust and waterproof protection, which can resist outdoor dust, light rain, and high and low temperature environments. It can work stably in a wide temperature range of -30 ℃ to 55 ℃, and can be used stably all year round in the northwest desert, coastal high humidity, and southern rainy areas. The power supply adopts detachable large capacity lithium batteries, and the continuous inspection time of a single battery can reach 8 hours. It is equipped with a dual battery rotation scheme to meet the uninterrupted inspection of large-scale power stations throughout the day; Supports Type-C fast charging, can be fully charged in two hours, and can be paired with a portable power bank for continuous power supply in outdoor environments without electricity. The data storage and transmission function is compatible with digital operation and maintenance. The device can store 50000 infrared thermal imaging images locally, and each image synchronously records the shooting time, temperature data, and equipment number; Supports Bluetooth wireless transmission to mobile phones and tablets, allowing for on-site viewing and sharing of images. The USB interface allows for batch export of images to a computer, paired with the Lexus photovoltaic thermal imaging analysis software, which automatically generates inspection reports, calculates the location of thermal hazards, fault types, and temperature exceedance values throughout the station, and forms a complete inspection ledger for the operation and maintenance team to track and rectify, and retain operation and maintenance files.

Rich photovoltaic exclusive application scenarios cover the full cycle operation and maintenance of power plants. In centralized ground photovoltaic power plants, LX-F100 can quickly scan the entire module array to locate heat spots caused by occlusion and hidden cracks; In the distributed photovoltaic inspection of industrial and commercial roofs, the handheld lightweight body is convenient for climbing the roof and detecting components in the far end and narrow gaps of the roof; The electrical system testing process covers inverters, combiner boxes, DC distribution cabinets, AC cables, and transformers to identify potential hazards such as loose wiring, overload heating, insulation aging, and temperature rise; The scenarios of component factory quality inspection, temperature monitoring of energy storage equipment, and safety acceptance of photovoltaic engineering completion are also applicable. Multiple large photovoltaic operation and maintenance enterprises in China have tested and compared the use of LX-F100 for full station infrared inspection. The efficiency of manual inspection has been improved by more than 70%, and the early identification rate of thermal hazards has been increased to 98%. It effectively avoids the risk of multiple component fires every year, reduces the loss of tens of millions of kilowatt hours of power generation, and significantly reduces the cost of power station operation and maintenance.

Under the trend of comprehensive implementation of preventive operation and safety control in the photovoltaic industry, non-contact infrared thermal imaging detection has become a necessity for power plant operation and maintenance. The Suzhou LAILX LX-F100 handheld infrared thermal imaging camera is based on the exclusive needs of the photovoltaic industry, abandoning the shortcomings of redundant functions and poor adaptability of general industrial thermal imaging cameras, and achieving four major breakthroughs in lightweight, high precision, intelligence, and high adaptability. In the future, Lexus will continue to upgrade its AI recognition algorithm, combine unmanned aerial vehicle thermal imaging linkage, cloud data warning function, and create a photovoltaic full scene temperature monitoring solution.
