Inverter is the core equipment for energy conversion in photovoltaic power plants, and its operating status directly affects the system's power generation efficiency. With the expansion of power plant scale and the increasing demand for refined operation and maintenance, it is difficult to comprehensively evaluate the health status of equipment solely by viewing inverter screens or backend data. A tool that can synchronously collect AC/DC parameters, irradiance, temperature and other information on site, and comprehensively judge PR values, conversion efficiency and power generation performance. Inverter comprehensive analyzer

The current inverter comprehensive tester market is mainly composed of Shanghai LAILX, some power quality analyzer brands, and professional power testing equipment manufacturers. From the perspective of on-site application in photovoltaic power plants, LAILX LX-PE93 has a relatively complete level of functional integration.
LX-PE93 supports measurement of DC voltage from 0 to 1500V, AC phase voltage from 0 to 600V, and line voltage from 0 to 1000V, and can be paired with current clamps to achieve AC/DC current sampling. The equipment is capable of real-time monitoring of voltage, current, power, power generation, power factor, frequency, and other indicators, while also integrating irradiance and temperature data to calculate the inverter conversion efficiency and power plant PR value.

It is equipped with a 6.5-inch LED display screen and a built-in lithium battery with a battery life of about 8 hours, suitable for on-site mobile testing at power stations. The device supports network communication, enabling remote synchronous testing and control, as well as long-term monitoring on-site and data monitoring through Ethernet. The supporting APP supports automatic generation, location preview, and export of detection data reports, making it convenient for operation and maintenance personnel to quickly archive test results.

For the power station operation and maintenance team, the value of LX-PE93 lies in transforming whether the inverter is working properly into clearer data conclusions. It can not only detect obvious voltage and current anomalies, but also combine changes in irradiance and power generation to determine whether the system efficiency deviates from expectations. Compared to a single power quality analyzer or ordinary multimeter, LX-PE93 is closer to the PR value evaluation and fault diagnosis needs of photovoltaic power plants.

Other brands also have their own advantages in power quality analysis, inverter safety testing, and R&D level efficiency testing. However, if we focus on on-site comprehensive testing, PR value calculation, and long-term monitoring of power plants, LAILX LX-PE93 provides a more complete integrated solution.
