In the refined management system of photovoltaic power plants, the inverter serves as a key hub for energy conversion, and its performance directly affects the power generation efficiency of the entire system. However, due to multiple factors such as component aging and environmental changes, the performance of the inverter will gradually deteriorate. To help power plant managers take the initiative in inverter performance management, Shanghai LAILX has launched the LX-PE93 inverter comprehensive tester, which provides reliable technical support for the optimized operation of power plants with specialized detection functions and intelligent analysis systems.

The LX-PE93 adopts an innovative testing architecture and synchronously collects complete data from the DC input and AC output terminals through a high-precision data acquisition module. It supports up to 1500V DC voltage and 1500A current measurement. The equipment can monitor the real-time working status of the inverter under different load conditions and accurately calculate the conversion efficiency curve under normal working conditions of the power station. At the same time, the device integrates high-precision irradiance meters and temperature sensors, eliminating the interference of temperature and lighting changes on test results through innovative environmental compensation technology, ensuring absolute accuracy in PR value calculation and efficiency evaluation.

In terms of intelligence and portability, LX-PE93 also performs outstandingly. The device is equipped with a 6.5-inch high brightness LED touch screen, with a simple and intuitive operation interface. The built-in lithium battery can provide up to 8 hours of battery life. The host and probe support 50 meter wireless communication, completely freeing themselves from the constraints of on-site wiring. It is worth mentioning that the device supports multiple communication protocols and networking communication functions. Test data can be transmitted in real-time wirelessly to the management platform or mobile app, achieving remote synchronous testing control and automatic data report generation. This diagnostic method based on measured data enables power plant operation and maintenance to shift from empirical judgment to scientific decision-making.

In actual power station operation and maintenance, LX-PE93 has demonstrated significant application value. The operation and maintenance team can regularly conduct performance tests on inverters in various areas of the power station and establish a comprehensive equipment health record; When abnormal efficiency is detected, detailed data analysis can accurately determine whether the problem is caused by power device aging or control strategy deviation. Suzhou LAILX has always been committed to the research and development of photovoltaic testing equipment. LX-PE93 not only meets the requirements of conventional performance testing, but its modular design also provides expansion possibilities for the testing of new inverter technologies. With the continuous advancement of photovoltaic technology, LX-PE93 will continue to drive the entire industry steadily towards the goal of greater efficiency and intelligence.
