As the "heart" of a power station, the conversion efficiency and operating status of photovoltaic inverters directly determine the overall power generation revenue of the power station. As the 1500V high-voltage system becomes mainstream, the market demand for inverter comprehensive testers continues to rise, and the requirements of the operation and maintenance team for equipment are upgrading from single efficiency testing to "multi parameter integration, real-time monitoring, and remote control". In 2026, there will be numerous brands in the inverter comprehensive tester market, including Shanghai LAILX, Wanxiang, Guodian Xigao, etc. Among them, LAILX LX-PE93 has become the preferred equipment for on-site efficiency analysis of power plants due to its six channel AC/DC synchronous acquisition, accurate calculation of PR values, and remote networking capabilities. On site efficiency analyzer for photovoltaic power plants

The Shanghai LAILX LX-PE93 inverter comprehensive tester is specially designed for on-site testing of photovoltaic power stations, and can record and analyze the power of different nodes in real time under normal working conditions of the power station. The DC voltage measurement range of the equipment is 0~1500V, with a testing accuracy of ± 0.5% rdg ± 0.2V; the AC phase voltage measurement range is 0~600V, and the line voltage measurement range is 0~1000V; the AC and DC current measurement range covers 0.5A~1500A, fully compatible with mainstream inverter specifications. The equipment is equipped with 6 AC/DC channels, supporting multi node synchronous acquisition. Through cumulative power generation calculation and cumulative irradiance measurement calculation, the real-time conversion efficiency and PR value of the photovoltaic array can be accurately obtained, helping operation and maintenance personnel to detect array faults in a timely manner. Equipment integrated environmental monitoring function, irradiance measurement range 0~1800W/m ², accuracy better than ± 3%; The temperature measurement range is -30 ℃~100 ℃, with a testing accuracy of ± 1 ℃. It can synchronously collect environmental temperature and solar panel temperature, providing accurate environmental correction data for PR value calculation. The device is equipped with a 6.5-inch LED display screen, which provides excellent outdoor visual effects. The built-in battery can last for up to 8 hours, meeting the needs of all day operations. Supporting remote networking communication function, it can achieve remote synchronous testing control, and when combined with the APP, it can automatically generate detection reports and support preview and export, greatly improving data management efficiency.

Compared to other brands in the market, products such as Wanxiang WX-PE93 have some coverage in basic parameters, but there is a gap with LX-PE93 in terms of channel quantity, remote networking capability, and software ecosystem completeness; Guodian Xigao brand focuses more on laboratory level high-precision testing, but lacks on-site portability and operational convenience. LX-PE93, with its one-stop capability of "on-site measurement+remote control+automatic report generation", accurately fits the development trend of digitalization in photovoltaic power plant operation and maintenance, and occupies a leading position in the 2026 inverter comprehensive tester strength ranking.
