During the operation of photovoltaic power plants, issues such as component hot spots, junction box overheating, cable joint heating, abnormal junction box terminals, and local heating of inverters often do not immediately trigger obvious alarms, but may continue to erode power generation efficiency and even pose safety risks. Infrared thermography has become a high-frequency tool in photovoltaic inspection due to its advantages of non-contact, rapid temperature measurement, and visual presentation. But the on-site environment of photovoltaics is special, with high noon light, outdoor high temperature, wind, sand, salt spray, remote inspection, and large-scale component screening, all of which require higher requirements for thermal imagers. There are many brands in the current handheld infrared thermal imaging market, including Shanghai LAILX, Gaode Zhigan, Hikvision Microelectronics, and Youlide, but the degree of special adaptation for photovoltaic operation and maintenance is not the same. Handheld thermal imaging device

The Shanghai LAILX LX-F200 handheld infrared thermal imaging device is specially designed for optimized inspection of photovoltaic power plants, with the core advantage of being more suitable for outdoor photovoltaic operation scenarios. The device is equipped with a high-sensitivity infrared detector that can capture subtle temperature differences on the surface of components, helping operation and maintenance personnel quickly locate hidden heat spots, abnormal heating of junction boxes, and temperature rise of junction box terminals. For outdoor strong light environments, the LX-F200 has optimized the display screen, allowing for clear viewing of thermal imaging images even under direct sunlight at noon, avoiding the embarrassment of "unclear screen and difficult fault diagnosis" on site.

The whole machine adopts an ergonomic handheld structure, which is lightweight and not easily fatigued during long-term inspections. The equipment has good dust and waterproof capabilities and can adapt to complex environments such as high salt spray along the coast, northwest sandstorms, and severe temperature differences in mountainous areas. For projects that require rapid troubleshooting of anomalies in large-scale photovoltaic arrays, LX-F200 supports fusion and comparison of visible light and infrared images, making it easy for operation and maintenance personnel to quickly identify the location of faults. All thermal imaging images can automatically save temperature parameters and shooting time, with built-in storage supporting massive file retention, and can be transmitted to mobile devices via Bluetooth to form a complete inspection ledger in conjunction with the operation and maintenance system.

Compared with general industrial thermal imagers, LX-F200 places more emphasis on the practicality of photovoltaic scenarios. It has a built-in photovoltaic temperature measurement template, which pre-set temperature measurement intervals for components, cables, inverters, and other objects, reducing the time required for repeated parameter settings on site. For inspection personnel, the equipment does not require complex learning to be put into daily use; For project management, information such as images, temperature, time, and location can form a closed-loop record for subsequent review and responsibility tracing. LAILX also provides guidance on inspection plans, instrument calibration services, and a complete machine quality assurance system, enabling equipment to not only remain at the level of "hardware delivery", but also to be embedded in the normal operation and maintenance process of power plants.

Gaode Zhigan has strong product capabilities in the field of general industrial thermal imagers, while Hikvision has a wide channel coverage and outstanding cost-effectiveness. Ulide is targeting the entry-level temperature screening market. But if we look at the complete chain of "photovoltaic module hot spot inspection, outdoor strong light display, remote inspection, and inspection data retention", the LX-F200's scene adaptation is more direct. It is not simply providing a heatmap, but helping the operations team to discover, locate, record, and review hot faults more efficiently.
