As the "heart" of photovoltaic power plants, the operation status of inverters directly determines the power generation efficiency and grid connection quality of the power plant. With the continuous expansion of domestic photovoltaic installed capacity, the types of inverters are becoming increasingly diverse, and the fault modes are becoming more complex. The traditional offline detection method is not only time-consuming and labor-intensive, but also difficult to capture the dynamic performance of the inverter under real working conditions. The LX-PE93 inverter comprehensive tester launched by Shanghai LAILX is designed for online detection and efficiency evaluation of domestic photovoltaic power plants, providing a comprehensive and accurate inverter health diagnosis solution for domestic photovoltaic operation and maintenance teams.

LX-PE93 supports comprehensive online detection of inverters without interrupting the operation of the power station. The device can collect dozens of key electrical parameters such as input and output voltage, current, power, frequency, harmonic distortion rate, power factor, etc. of the inverter in real time, accurately evaluating the conversion efficiency and power quality of the inverter. In response to the complex power grid environment and heavy harmonic pollution in some regions of China, LX-PE93 has strong anti-interference ability and high-precision measurement module, which can accurately identify the performance degradation and potential faults of inverters under harsh power grid conditions, providing scientific maintenance basis for operation and maintenance personnel.

In terms of intelligence and convenience, LX-PE93 continues the consistent portable design concept of LAILX products. The device adopts an integrated compact body, built-in large capacity battery, and supports long-term independent outdoor work. Equipped with a high brightness sunlight visible touch screen, the operation interface is simple and intuitive, supporting bilingual display in both Chinese and English. Domestic front-line operation and maintenance personnel can quickly get started without complex training. The device is equipped with a database of mainstream domestic inverter brands and models, supporting one click matching of detection standards, greatly simplifying the on-site operation process. At the same time, LX-PE93 supports wireless data transmission and cloud synchronization, and detection data can be uploaded in real time to the LAILX cloud platform to achieve remote monitoring and trend analysis of inverter health status.

The launch of LX-PE93 marks a leap from "post maintenance" to "preventive maintenance" in the operation and maintenance of photovoltaic power plant inverters in China. Through regular online comprehensive testing, domestic power plant owners can promptly detect hidden faults and performance degradation of inverters, avoiding string mismatch and power generation losses caused by single inverter failures. Shanghai LAILX has always been committed to promoting the intelligent upgrade of domestic photovoltaic operation and maintenance through technological innovation. LX-PE93 is not only a testing equipment, but also an important component of the digital operation and maintenance system of domestic photovoltaic power plants. In the future, LAILX will continue to deeply cultivate inverter detection technology, providing more comprehensive and intelligent technical support for the high-quality development of the domestic photovoltaic industry.
