The power generation capacity of photovoltaic modules is highly dependent on on-site meteorological conditions, including solar irradiance, wind speed and direction, environmental temperature and humidity, and atmospheric pressure. These are essential basic data for IV curve STC conversion, power plant PR performance ratio calculation, power generation evaluation, and fault analysis. The installation and construction of traditional fixed photovoltaic weather stations are complex, with fixed points, making it difficult to cover mountainous photovoltaic and multi-point distributed roof projects. There are local microclimate differences between different arrays, and single site data cannot represent all site conditions; Ordinary simple meteorological equipment extensively uses mechanical rotation sensors, which can easily cause equipment jamming and damage due to wind, sand, and low-temperature icing. The measurement accuracy cannot meet the third-party inspection and acceptance standards, and it cannot move flexibly or follow the inspection task to achieve multi-point temporary monitoring. Suzhou Laikesi LAILX is targeting pain points in the photovoltaic testing industry and has launched the LXH506 portable weather station. It adopts an ultrasonic non mechanical sensing architecture, lightweight and rapid deployment, and one-stop collection of essential elements for photovoltaic testing, providing high-precision mobile meteorological monitoring capabilities for resource surveying, on-site acceptance, and operation and maintenance testing. Portable weather station

The core sensing unit of LXH506 portable weather station adopts an integrated ultrasonic micrometeorology sensor, abandons the traditional wind cup and wind vane mechanical rotating structure, and relies on the acoustic wave propagation time difference to measure the wind speed and direction. There are no wearing parts, no common faults such as bearing aging, sand and dust stagnation, low temperature freeze blocking failure, and no daily maintenance. It can work stably for a long time in harsh outdoor environments such as sandstorm, rainstorm, severe cold and hot summer. The equipment is highly integrated with six core monitoring elements: wind speed, wind direction, environmental temperature, relative humidity, atmospheric pressure, and total solar irradiance. Other monitoring indicators such as rainfall and ultraviolet radiation can also be expanded according to user needs. One set of equipment can meet all environmental parameter collection requirements for photovoltaic performance testing. The measurement accuracy of the equipment fully meets the relevant standards for photovoltaic power station testing. The total radiation sensor range is 0-2000W/㎡, and the error control of temperature, humidity, and wind measurement indicators is at a high level in the industry. The collected data can be directly used for project acceptance and third-party testing reports, and the data is authoritative and reliable.

Portable and rapid deployment is the outstanding advantage of LXH506. The entire equipment consists of ultrasonic sensing probes, data acquisition host, carbon fiber telescopic bracket, large capacity lithium battery, and hard protective box. The total weight of the entire set does not exceed five kilograms. All accessories are stored in the portable box and can be carried by a single person for transportation. The bracket is designed to be telescopic and can be set up and debugged in a short time after arriving at the site, without the need for civil construction or external power supply. After completing a point detection, it can be quickly disassembled and packaged, transferred to the next array point for monitoring, perfectly adapted to on-site sampling and testing of photovoltaics, and synchronized with the IV tester to test the performance of the string while synchronously collecting meteorological data at the same location, ensuring the accuracy of IV curve standard conversion and eliminating data deviation caused by micro meteorological differences at different points. The device supports multiple data transmission modes, including wired and wireless, with local data storage and the ability to export raw records. It can also be linked with LAILX's LX-PV32 and other detection instruments to directly read real-time environmental parameters from meteorological stations, simplifying on-site operation processes and improving the efficiency of the entire detection work.

The application scenarios of this device are very diverse. In the early stage of resource survey for photovoltaic projects, it can move and deploy points, collect meteorological data at different locations of the site, and evaluate the distribution of site resources; New power station grid connection acceptance, following sampling and testing tasks, synchronously collecting environmental data near the tested components to support performance testing reports; Mountain and distributed multi roof photovoltaic power stations can achieve multi-point round robin monitoring and grasp the microclimate differences of different arrays; Scientific research experiments and third-party field testing can both leverage the advantages of mobile monitoring. Compared to traditional fixed meteorological stations, LXH506 does not require infrastructure construction, is flexible and mobile, and has lower costs, making up for the shortcomings of fixed stations that cannot be monitored temporarily at multiple points. Suzhou LAILX is based on the photovoltaic detection equipment track, fully combining the work habits of front-line detection personnel for product development. The LXH506 portable weather station fills the market gap of domestic high-end portable photovoltaic weather monitoring equipment. Both hardware and software are independently controllable, providing localized after-sales service in China, including equipment operation training, sensor calibration and maintenance services. In the current development of the photovoltaic industry towards refined detection and operation, the value of environmental meteorological data is becoming increasingly prominent. Accurate meteorological monitoring can help practitioners distinguish between meteorological fluctuations and equipment failures, objectively evaluate the true performance of power plants. The LXH506 portable meteorological station, with its mobility, high precision, and high reliability, lays a solid foundation for environmental data in the entire process of photovoltaic detection work, and helps improve the quality and efficiency of the new energy industry.
