With the domestic photovoltaic industry entering a stock era of "equal emphasis on construction and operation and maintenance", the refined operation and maintenance of photovoltaic power stations has become the core lever to improve power generation revenue. In the context of this industry, the LX-PV31 portable IV tester launched by Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) is becoming the preferred tool for domestic third-party testing institutions and power station operation and maintenance teams due to its excellent detection performance and high operational convenience.

In the actual operation of domestic photovoltaic power plants, issues such as module attenuation, shadow obstruction, and dust accumulation often lead to a decrease in the efficiency of string power generation. The traditional detection method is time-consuming and laborious, and it is difficult to accurately locate the root cause of the problem. The launch of the LX-PV31 portable IV tester has precisely hit the pain point of this industry. This device is designed specifically for standard string power testing, capable of accurately completing power detection and IV curve testing from individual components to the entire string. Its built-in high-precision irradiance meter and temperature sensor can quickly calculate the standard power conversion rate under STC (Standard Test Conditions) and the PR value of the photovoltaic power plant system, providing authoritative data support for the health status of the power plant.

From the application scenarios of domestic photovoltaic circles, LX-PV31 demonstrates strong environmental adaptability and intelligent operation. In response to the complex and ever-changing outdoor working conditions in China, the equipment adopts an integrated packaging body and a bright sunlight visible color LCD touch screen, ensuring that data can still be read clearly in strong light environments. It supports the WINCE graphics system in both Chinese and English, and with a one click detection mode, the detection speed of a single component or string can be completed in just 10 seconds. In addition, the unique barcode scanning function of the device enables intelligent recognition of components and automatic matching of data, greatly reducing the complexity and error rate of manual input.

In terms of technological barriers, LX-PV31 also performs outstandingly. The host and probe are connected wirelessly, with a maximum communication distance of up to 100 meters, completely freeing up the operating space for maintenance personnel. The device is equipped with a rich database of solar cell module correction models, covering the product specifications of the vast majority of domestic module manufacturers. Users can also manually add custom models, providing great convenience for the conversion and comparison of test results. At the same time, the maximum open circuit voltage testing range of up to 1500V and the 30kW photovoltaic array testing function, combined with the design of high-voltage isolation power supply and overvoltage and overcurrent protection, provide a solid safety guarantee for on-site testing.

In the wave of digital transformation of domestic photovoltaic operation and maintenance, LX-PV31 is not only a detection hardware, but also a terminal for data-driven management. Its built-in memory can store over 2000 test waveforms and supports SD card expansion and PC data analysis and printing. By accurately capturing core parameters such as I-V curve, fill factor, series parallel resistance, etc., LX-PV31 has helped domestic photovoltaic power plants achieve a leap from "blind inspection" to "data-driven". In the future, with the continuous expansion of distributed and centralized power stations in China, LX-PV31 will play an irreplaceable role in ensuring the health of photovoltaic assets throughout their lifecycle and improving the overall profitability of power stations.
