As the "heart" of a photovoltaic power station, the conversion efficiency of the inverter directly determines the overall power generation efficiency of the power station. Accurately detecting the efficiency of the inverter and monitoring the operation status of the power station in real time are the core links of photovoltaic power station construction acceptance and operation and maintenance management. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) focuses on the efficiency testing needs of photovoltaic power plants and has launched the LX-PE93 inverter efficiency tester. With high-precision measurement, multifunctional integration, and intelligent control, it has become the core equipment for photovoltaic inverter performance evaluation and power plant efficiency monitoring, providing a solid guarantee for the efficient operation of photovoltaic power plants.

The LX-PE93 inverter efficiency tester is a professional equipment specially designed by Lexus for electrical performance testing of photovoltaic power plant inverter systems. It can be adapted to various types of inverters such as string and centralized inverters, as well as efficiency value testing scenarios such as combiner boxes and PR systems, fully meeting the testing needs of different nodes in photovoltaic power plants. This device uses advanced current clamps for current sampling, which can record and analyze real-time parameters such as voltage, current, and power of different nodes under normal operation of the power station. It does not require shutdown detection and does not affect the normal power generation of the power station. It completely solves the problem of traditional detection methods requiring power outage and affecting power generation revenue.

In terms of core measurement performance, LX-PE93 demonstrates excellent accuracy. It supports the 1500V DC voltage testing standard and can simultaneously measure 4 DC and 3 AC parameters. It accurately collects real-time voltage, current, power, power generation, power factor and other data of the inverter input and output, and automatically calculates the inverter conversion efficiency and power station PR value. The measurement error is small, ensuring the reliability of the detection data. The equipment is equipped with a high-precision irradiation system and temperature monitoring module, which can synchronously collect parameters such as irradiance and environmental temperature, and correspond electrical performance data with environmental data one by one, providing comprehensive and scientific basis for inverter efficiency evaluation and power plant efficiency analysis.

Intelligence and remote control are the prominent advantages of LX-PE93. The device has powerful networking and communication functions, supporting multiple communication methods such as Ethernet and 4G, and can achieve remote synchronous testing and control. Operators can set parameters, start testing, and view data of the detector through terminal devices without physically visiting the site, greatly saving manpower and time costs, especially suitable for the detection and monitoring of photovoltaic power plants in remote areas. At the same time, the equipment supports long-term on-site fixed monitoring, with a high level of protection, and can adapt to complex outdoor environments, achieving 24-hour uninterrupted monitoring of the operation status of inverters and power stations, and timely capturing operational abnormalities.

In terms of data processing and analysis functions, LX-PE93 also performs well. The device is equipped with a built-in data storage module that can store detection data for a long time. It supports data export and upload, and is paired with Lexus' dedicated data analysis software to conduct in-depth analysis, comparison, and trend prediction of inverter efficiency, power generation, PR value, and other data. It automatically generates professional detection reports. Through the calculation and analysis of cumulative power generation and cumulative irradiance, the equipment can accurately evaluate the real-time conversion efficiency of photovoltaic arrays, timely detect array faults, inverter performance degradation and other issues, and provide reliable support for fault diagnosis and operation and maintenance decisions.

In terms of portability and power supply design, LX-PE93 fully considers outdoor detection needs. The device is compact in size and lightweight, making it easy to carry to various power plant sites; Equipped with a large capacity lithium battery, it can work continuously for 3-4 hours and is suitable for outdoor scenarios without external power supply, ensuring the continuity of testing work. It adopts a user-friendly interface, paired with a high-definition display screen, with intuitive parameter display and simple operation process. Even non professionals can quickly master the usage method and lower the threshold for device use.

From the perspective of application value, the LX-PE93 inverter efficiency tester runs through the entire lifecycle of photovoltaic power plants. During the construction and acceptance stage of the power station, the inverter can undergo factory inspection and on-site acceptance to ensure that its performance meets the design standards and avoid unqualified equipment from being connected to the power station; During the operation and maintenance of the power station, the efficiency of the inverter can be regularly monitored, the PR value of the power station can be monitored, and problems such as inverter faults, component attenuation, and line losses can be detected in a timely manner to guide operation and maintenance personnel in precise maintenance and improve the power generation efficiency of the power station; At the same time, this device is also suitable for research and development testing, quality control of inverter manufacturers, as well as photovoltaic system efficiency research in scientific research institutions.

As a professional manufacturer in the field of photovoltaic testing equipment, Suzhou Laikesi has built the LX-PE93 inverter efficiency tester with deep technical accumulation and rich industry experience, which integrates multiple advantages such as high-precision measurement, intelligent control, and convenient operation. Compared to imported similar equipment, LX-PE93 not only has a higher cost-effectiveness, but also has localized technical support and comprehensive after-sales service. It can quickly respond to customer needs and solve various problems during equipment use, becoming the preferred testing equipment for domestic photovoltaic enterprises.

Under the promotion of the "dual carbon" goal, the photovoltaic industry has ushered in large-scale development, and the refinement and intelligence of power station operation and maintenance have become an inevitable trend. The LX-PE93 inverter efficiency tester will use its precise detection capability and intelligent control function to help photovoltaic power plants improve power generation efficiency, reduce operation and maintenance costs, and promote the development of the photovoltaic industry towards high efficiency and intelligence. In the future, Suzhou Laikesi will continue to deeply cultivate the field of photovoltaic testing, constantly iterate and upgrade product technology, and provide more comprehensive and professional solutions for the full lifecycle management of photovoltaic power plants.
