With the continuous increase in the number of domestic photovoltaic power stations, the operation and maintenance pressure of distributed industrial and commercial rooftops, large ground power stations, and mountain photovoltaic projects has been increasing year by year. Temperature related faults such as component hot spots, junction box heating, poor line contact, and abnormal inverter temperature occur frequently, which can cause power generation attenuation and decrease in electricity revenue, and even lead to major safety accidents such as component burnout and electrical fires. Traditional manual inspections rely on visual observation and single point detection with contact thermometers, which are inefficient and unable to identify hidden temperature anomalies. Large scale power plant inspections have high labor costs and high rates of missed detections. Based on the core technology of infrared thermal imaging, Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) has independently developed the LX-F100 handheld infrared thermal imaging instrument, which is specially optimized for photovoltaic and power operation and maintenance scenarios. With ultra-high thermal sensitivity, high-definition imaging, and long battery life portable design, it realizes non-contact rapid global temperature measurement, accurately locates various hidden temperature faults, and comprehensively empowers the intelligent operation and maintenance upgrade of photovoltaic power plants. Compact, portable, precise imaging

The LX-F100 is equipped with a 320 × 240 high-resolution uncooled infrared focal plane detector, with a response band covering the long wave infrared range of 7 μ m to 14 μ m. It has strong resistance to dust, water vapor, and strong light interference, and can stably image on outdoor sunny, cloudy, early morning, and evening days. The device's thermal sensitivity is better than 0.05 ℃ @ 30 ℃, and can capture extremely small temperature differences. Even slight aging of battery cells and temperature rise caused by virtual connection of wiring terminals can be clearly distinguished in the thermal imaging spectrum, eliminating the problem of small thermal spot leakage from the root. It is a performance benchmark among handheld thermal imagers of the same level. The temperature measurement range covers from 20 ℃ to 300 ℃, perfectly adapting to the dual scenarios of normal temperature inspection of photovoltaic modules, high temperature fault detection of inverters, combiner boxes, and cable joints. The equipment is equipped with multiple intelligent temperature measurement algorithms, which optimize the rendering of the image for the uniform temperature field of photovoltaic cells, automatically distinguish between normal working areas and abnormal heating points, and mark the highest and lowest temperature values in real-time on the screen. The operation and maintenance personnel can lock the fault location at a glance.

The product follows an industrial grade handheld and portable design. The body adopts an ergonomic anti slip grip, which is lightweight and can withstand long-term outdoor inspections without hand fatigue. The body shell is IP54 dustproof and waterproof, resistant to drops and impacts, and suitable for harsh working environments such as construction sites, mountains, and coastal areas. The screen is equipped with a high brightness LCD touch screen, which provides clear and visible images under strong outdoor light. It supports three display modes: infrared, visible light, and fused image. The infrared spectrum is overlaid with the visible light image to accurately correspond to the actual physical location of the fault and avoid misjudgment. The whole machine is equipped with a large capacity lithium battery, which can work continuously for more than 15 hours on a single full charge. It can cover the entire power station inspection in a single day without the need for intermediate charging. The equipment is equipped with a fast charging adapter and a backup battery selection solution to meet the long-term field inspection needs. The body is equipped with a local storage module that can store tens of thousands of thermal imaging images and temperature measurement data. It supports photography and video recording functions. Each imaging file automatically records the shooting time, temperature value, and equipment number, making it easy to archive faults and establish operation and maintenance records in the future; Paired with USB and wireless data transmission functions, the map can be quickly imported into the computer. Equipped with LAILX professional temperature analysis software, it supports temperature curve drawing, batch data export, and automatic generation of inspection reports, adapting to the standardized file management requirements of power station operation and maintenance.

The exclusive optimization function for photovoltaic operation and maintenance is the core differentiation advantage of LX-F100. The device is equipped with a photovoltaic specific temperature measurement template, which can switch component inspection mode with one click, automatically shield environmental temperature and sunlight reflection interference, and accurately calculate the actual working temperature difference of the battery cells; Support area box selection temperature measurement, center point temperature measurement, and high/low temperature tracking alarm functions. After setting the temperature threshold, the abnormal high temperature area on the screen will automatically highlight and remind, without the need for manual temperature comparison, greatly improving the inspection speed. The operation and maintenance personnel can scan the photovoltaic array at a constant speed with handheld devices, and can complete the temperature measurement of dozens of components in the entire area every minute. The inspection efficiency is more than ten times higher than traditional contact temperature measurement. Large ground power stations can complete the full coverage inspection of megawatt level arrays in a single day, effectively reducing the investment of operation and maintenance personnel and lowering the inspection cost of enterprises. In addition to the photovoltaic industry, LX-F100 is also suitable for multiple scenarios such as power line inspection, industrial equipment temperature measurement, building HVAC testing, energy storage equipment temperature monitoring, etc. It can be used for multiple purposes, reducing the cost of purchasing multiple instruments for enterprises.

In terms of safety operation and maintenance value, LX-F100 achieves pre fault troubleshooting, which can identify faults in advance during the mild heating stage of hot spots, repair and replace faulty components in a timely manner, avoid irreversible scrapping caused by local high temperature continuous burning of solar cells, and extend the overall service life of photovoltaic modules; Pre check potential heating hazards in cables, combiner boxes, and inverters to prevent short circuits and fires, reduce downtime for maintenance, and ensure continuous and stable power generation. According to on-site testing data from multiple large power generation groups and third-party operation and maintenance enterprises, equipped with LX-F100 for regular infrared inspections, the detection rate of hidden faults in power stations has increased by 80%, the annual comprehensive operation and maintenance cost has been reduced by 30%, and the power generation revenue has significantly increased.

As a leading domestic photovoltaic testing equipment enterprise, Suzhou LAILX independently develops and produces the LX-F100 core infrared detector and temperature measurement algorithm, eliminating dependence on overseas core components. The price is much lower than imported brands under the same performance. At the same time, it provides localized full cycle services: one-year warranty for the whole machine and two-year warranty for the core detection module. Technical service teams are equipped in various regions across the country to provide on-site operation training, equipment calibration, and fault repair services. The supporting software is updated and iterated for free for life, continuously optimizing the photovoltaic temperature measurement algorithm to meet the testing needs of new large-sized and double-sided components.

In the context of accelerating the intelligent transformation of the new energy industry, refined and pre installed operation and maintenance have become the mainstream trend of industry development. Infrared thermal imaging non-contact detection technology is an indispensable core means of photovoltaic safety operation and maintenance. The Suzhou LAILX LX-F100 handheld infrared thermal imaging camera breaks the monopoly of the foreign thermal imaging camera market with multiple advantages such as precise temperature measurement, portability and durability, multi scene adaptation, and high cost-effectiveness, providing reliable domestic temperature detection equipment for the domestic photovoltaic and power industries.
