As the "heart" of photovoltaic power plants, the conversion efficiency and operating status of inverters directly determine the power generation efficiency of the entire system. However, during long-term operation, the performance of inverters will gradually deteriorate due to factors such as component aging and environmental changes. The LX-PE93 inverter comprehensive tester launched by Shanghai LAILX provides accurate data support for inverter performance evaluation and power station efficiency optimization with non-invasive real-time monitoring and intelligent analysis capabilities, becoming the core tool for refined operation and maintenance of power stations.

The core value of LX-PE93 lies in its ability to conduct comprehensive performance checks on inverters under normal operating conditions in power plants. The device uses high-precision current clamps for non-contact sampling, synchronously collecting key parameters such as voltage, current, and power from the DC input and AC output terminals, and calculating the conversion efficiency of the inverter in real time. At the same time, the whole machine is equipped with high-precision irradiance meters and temperature sensors, which can automatically collect environmental irradiance, environmental temperature, and solar panel temperature. Combined with accumulated power generation and irradiance data, the system efficiency (PR value) of the photovoltaic power station is intelligently calculated, providing quantitative evaluation standards for the health status of the power station.

In terms of intelligence and remote management, LX-PE93 has demonstrated strong technological capabilities. The device supports networking communication function and can transmit test data in real-time to the management platform through wireless (up to 50 meters) or Ethernet, achieving remote synchronous testing control and long-term monitoring. The supporting professional data analysis software can automatically generate detection reports, support report preview, export, and positioning, and help the operation and maintenance team quickly grasp the trend of inverter performance changes. When abnormal efficiency is detected, detailed data analysis can accurately determine whether the problem is caused by power device aging, control strategy deviation, or other factors, shifting operation and maintenance decisions from empirical judgment to scientific diagnosis.

The application scenarios of LX-PE93 cover performance testing and PR value evaluation of string inverters, centralized inverters, and combiner boxes. The equipment has a high level of protection and can operate stably in a wide temperature range of -10 ℃ to 50 ℃. It is equipped with a large capacity lithium battery that supports 8-hour continuous operation, meeting the long-term monitoring needs of outdoor power plants. Its modular design and rich communication interfaces also reserve expansion space for the testing of future new inverter technologies.

Shanghai LAILX is committed to improving the power generation revenue of photovoltaic power plants through technological innovation. The LX-PE93 inverter comprehensive tester not only helps power plant managers establish a comprehensive equipment health record, but also analyzes the performance degradation law of inverters through long-term data accumulation, providing scientific basis for equipment replacement and operation strategy optimization. In the process of moving towards intelligent operation and maintenance in the photovoltaic industry, LX-PE93, with its precise, efficient, and intelligent comprehensive performance, is becoming an important technical guardian to ensure the safe operation of power plants and improve power generation efficiency.
