As the "heart" of photovoltaic power plants, the conversion efficiency and operating status of inverters directly determine the overall power generation revenue of the system. However, in complex outdoor working conditions, how to accurately evaluate the true performance of inverters and calculate the system efficiency (PR value) of power plants has always been a challenge faced by the industry. The LX-PE93 inverter comprehensive tester launched by LAILX in Shanghai provides an authoritative technical decoder for the refined operation of photovoltaic power plants with its comprehensive testing dimensions and intelligent data analysis. Inverter efficiency tester

LX-PE93 is designed specifically for on-site power monitoring and inverter efficiency analysis in photovoltaic power plants. The equipment adopts high-precision current clamp for non-contact sampling, supporting wide range measurement of 0 to 1500V DC voltage and 0 to 1000V AC line voltage, and can simultaneously meet the testing requirements of string and centralized inverters. Its core advantage lies in the fact that the entire machine is equipped with a professional irradiance acquisition system and environmental temperature sensors, which can synchronously record real-time power, power generation, and environmental irradiance data on the AC and DC sides during normal grid connected power generation of the power station. Through its built-in intelligent algorithm, LX-PE93 can automatically calculate and generate PR values, accurately reflecting the true conversion efficiency of the photovoltaic array, and helping operation and maintenance personnel detect performance degradation caused by equipment aging, control strategy deviations, or environmental factors in a timely manner.

In terms of digitalization and remote operation and maintenance, LX-PE93 has demonstrated strong scalability. The device supports network communication and remote Ethernet monitoring, and test data can be synchronized in real-time to the cloud management platform through wireless means. The operation and maintenance team can preview and export professional inspection reports through PC or mobile APP without physically visiting the site, achieving remote diagnosis and full lifecycle management of inverter health status. In addition, the 6.5-inch high brightness LED touch screen and up to 8 hours of built-in battery life ensure stable operation of the device in harsh outdoor environments.

From performance verification during the acceptance period of the power plant to efficiency degradation analysis during the operation period, LX-PE93 is driving the transformation of the operation and maintenance mode of photovoltaic power plants from "experience judgment" to "data-driven" with its PR value measurement accuracy better than ± 1% and extremely high data reliability. The Lexus LX-PE93 is continuously unleashing the value of every kilowatt hour of green electricity from photovoltaic power plants through precise "pulse diagnosis".
