LX-PE93 is used for electrical performance testing of photovoltaic power plant inverter systems, which can monitor the on-site power of photovoltaic power plants. The equipment uses current clamps for current sampling, which can record and analyze the power of different nodes in the power station in real time under normal working conditions. The whole machine is equipped with an irradiation system, which can measure accurate real-time power generation efficiency at various nodes of the power station and automatically generate PR values in the system. Its innovative testing architecture provides a comprehensive data foundation for the performance analysis of inverters by synchronously collecting complete data from the DC input and AC output terminals.

The high-precision data acquisition module can monitor the working status of the inverter in real time under different load conditions, and the intelligent analysis system can accurately calculate the conversion efficiency curve of the inverter. Innovative environmental compensation technology can eliminate the impact of temperature changes on test results, ensuring accurate performance data under different operating conditions. It is worth mentioning that the device supports multiple communication protocols, and test data can be transmitted in real-time wirelessly to the management platform, providing convenience for remote monitoring and fault diagnosis of the device.

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 an inverter is found to have abnormal efficiency, detailed testing data can be used to analyze the root cause of the problem and accurately determine whether the performance degradation is caused by power device aging, control strategy deviation, or other factors. This diagnostic method based on measured data has shifted the focus of power plant operation and maintenance from empirical judgment to scientific decision-making, greatly improving the pertinence and effectiveness of maintenance work.

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, with a testing accuracy of ± 0.5% rdg ± 0.2V; the irradiance measurement range is 0-1800W/m ², with a measurement accuracy better than ± 3%; The measurement accuracy of PR value is better than ± 1%. The built-in lithium battery has a range of 8 hours, weighs 5.8kg, and is highly portable. It is suitable for on-site testing in power stations and can remotely monitor data processing through Ethernet.

At present, as the domestic photovoltaic industry accelerates the fine operation and maintenance of power stations, LX-PE93 provides strong technical support for the development of the industry with its innovative technical design and reliable performance. This advanced inverter efficiency tester not only represents the current technological level of the industry, but also points out the direction for the future development of the photovoltaic detection field, and will continue to promote the domestic photovoltaic industry towards the goal of greater efficiency and intelligence.
