Photovoltaic power stations are exposed to complex outdoor environments for extended periods, making them susceptible to issues such as bird droppings, dust accumulation, hidden cracks in solar cells, diode failures, and faulty soldering in junction boxes, which can easily induce hot spot effects. Electrical faults such as loose wiring terminals in combiner boxes, aging cable insulation, and overload of inverter power modules can also lead to localized abnormal temperature rises. These early subtle heating hazards are invisible to the naked eye, and ordinary temperature guns can only measure temperature at a single point, making it easy to miss inspections. The continued development of these hazards can result in component burnout, line short circuits, and even fires in power stations, causing significant economic losses and safety risks. Shanghai LAILX has launched the LX-F100 handheld infrared thermal imager, specifically designed for preventive maintenance and operation in the photovoltaic industry. Relying on ultra-high sensitivity infrared detection and photovoltaic-specific fault recognition algorithms, it enables non-contact full-field temperature visualization inspection, quickly locating various thermal fault hazards in power stations.

The LX-F100 handheld infrared thermal imaging device is equipped with a high-performance uncooled infrared focal plane detector, achieving an infrared resolution of 320×240 and a thermal sensitivity of less than 0.05℃. It can capture subtle temperature differences as low as 0.1℃, and even minor temperature rises on component surfaces can be clearly displayed in the thermal imaging images. The device is equipped with the LAILX intelligent analysis algorithm dedicated to photovoltaics, which optimizes the recognition logic for common thermal faults in the photovoltaic industry. When scanning photovoltaic arrays, it automatically marks typical faults such as component hot spots, junction box overheating, temperature rise due to series-parallel mismatch, and poor contact of MC4 connectors. The images simultaneously display the highest temperature, lowest temperature, and temperature difference values, allowing operation and maintenance personnel to intuitively judge the severity of the fault and distinguish between normal temperature rises and potential hazards. The instrument supports a dual-range temperature measurement mode, with a wide range covering the temperature measurement needs of photovoltaic components, cables, combiner boxes, inverters, and other equipment, balancing high-temperature fault capture and small temperature difference identification.

At the industrial design level, the LX-F100 fully considers the needs of long-duration outdoor handheld inspections. Its lightweight body adopts ergonomic design, making it less prone to fatigue even after prolonged holding. The entire casing is made of high-strength wear-resistant material, with an IP54 protection rating, dust and water resistance, and adaptability to harsh outdoor conditions such as rain, snow, dust, and extreme temperatures. Equipped with a high-brightness color display, it remains clearly visible even under strong outdoor light. It supports contrast display of infrared images and visible light frames, facilitating maintenance personnel to match thermal imaging anomalies with on-site objects one-to-one, quickly locating the fault position. The device is equipped with a large-capacity lithium battery, which can support full-day outdoor inspection work on a single full charge. It supports local image and video storage, allowing for one-click capture of thermal images and recording of temperature measurement videos. The temperature data is automatically saved, and the stored files can be exported to a computer to generate inspection reports and retain maintenance archives.

The LX-F100 has a wide range of application scenarios. In addition to hot spot inspection of photovoltaic power station components, it can also be used for temperature detection of electrical equipment such as inverters, distribution cabinets, and cable connectors. It can also be extended to areas such as power operation and maintenance, industrial equipment inspection, and building energy efficiency testing. In photovoltaic operation and maintenance work, this device can serve as a standard tool for daily inspection, regularly conducting infrared scanning of photovoltaic arrays to complete early warning and disposal before irreversible damage caused by hot spots. During the grid connection acceptance phase of the power station, a full-field infrared survey is conducted to identify issues such as loose wiring and component defects left over from the construction phase. In the fault analysis and troubleshooting phase, thermal imaging images are used to analyze the root cause of temperature rise, providing data support for the formulation of maintenance plans.

As the number of existing photovoltaic (PV) power plants in China continues to rise, the safety operation and maintenance of these power plants has become increasingly important to both owners and maintenance companies. Infrared thermal imaging preventive inspections have become a crucial part of the standardized process for PV operation and maintenance. The LAILX LX-F100 handheld infrared thermal imager from Shanghai, with its core advantages such as precise temperature measurement, high-definition imaging, PV AI fault recognition, and robust portability, assists maintenance personnel in quickly identifying thermal hazards, reducing fire risks in PV power plants from the source, and minimizing power generation losses caused by component damage. LAILX continues to deeply explore the field of PV safety inspection, continuously iterating infrared algorithms and hardware performance, providing reliable detection equipment support for the safe operation of PV assets.
