With the sustained high-speed development of the domestic photovoltaic industry, various large-scale ground power stations, mountain photovoltaic, industrial and commercial distributed, and household photovoltaic projects have been implemented on a large scale. The work pressure of post operation and maintenance, on-site acceptance, and fault diagnosis of power stations continues to rise. As the core unit of power generation in a power station, the actual output power, attenuation, and electrical performance of photovoltaic string directly determine the overall power generation revenue. However, traditional detection equipment generally suffers from practical pain points such as insufficient range, slow testing speed, high environmental interference, and poor outdoor portability. In response to these industry challenges, Shanghai LAILX closely follows the trend of technological evolution and launches the LX-PV32 portable IV tester, providing a complete and reliable domestic on-site performance testing solution for power plant EPC enterprises, third-party testing institutions, and photovoltaic operation and maintenance service providers. Current voltage power curve detector

LX-PV32 is specially designed for the current mainstream 1500VDC high-voltage photovoltaic system, with a comprehensive voltage range covering 10V to 1500V and a maximum current of 30A. It can fully measure more than 20 core electrical parameters such as I-V curve, P-V curve, open circuit voltage, short-circuit current, peak power, fill factor, conversion efficiency, and series parallel resistance. This device is perfectly compatible with the vast majority of photovoltaic products on the market, such as N-type, P-type, half sheet, and double glass. Whether it is a single module or a whole string, it can handle the full dimensional performance testing with ease. In terms of measurement accuracy, LX-PV32 adopts self-developed high-precision load modules and four wire measurement technology. The voltage measurement accuracy reaches ± 0.5% ± 0.2V, and the current accuracy is as high as 0.001A. Even for old strings with weak performance attenuation, it can accurately capture subtle changes in the curve, providing solid data support for power plant PR value calculation and power attenuation evaluation.

In terms of practicality for outdoor operations, LX-PV32 fully considers complex working conditions and deeply optimizes the portability of the entire machine. The device adopts an integrated compact body, with a total weight of less than 6kg, and is equipped with a high-strength customized protective suitcase, which can be easily carried and quickly deployed by a single person. Equipped with a large capacity replaceable lithium battery, it can work continuously for more than 10 hours on a single charge, completely freeing itself from the constraints of outdoor scenarios without power. The device is equipped with a 6.5-inch high brightness color LCD touch screen, which supports clear visibility under sunlight and bilingual operation in Chinese and English. Front line operation and maintenance personnel can independently carry out their work after simple training. In terms of testing efficiency, a complete scanning and detection of a photovoltaic string only takes about 10 seconds, with short testing intervals and support for continuous batch testing, greatly improving the efficiency of full-scale detection of large power plants.

In terms of intelligence and data management, LX-PV32 also performs outstandingly. The equipment is equipped with high-precision wireless irradiance sensors and temperature probes, which can synchronously collect solar irradiance, ambient temperature, and component backplane temperature. With built-in algorithms, it automatically completes STC standard condition correction of test data, effectively eliminating data deviation caused by outdoor lighting fluctuations and temperature changes. The host has a built-in large capacity storage space, which can store more than 2000 sets of complete IV test waveform data, and supports quick export from a USB flash drive. With professional PC analysis software, users can easily complete waveform review, horizontal comparison of multiple sets of data, and automatic generation of standardized detection reports, perfectly meeting the full process management needs of power plant acceptance, operation and maintenance records, and quality traceability. The launch of LX-PV32 not only fills the market gap of 1500V high-voltage portable IV detection, but also reshapes the new standard of portable IV detection industry with the core values of high precision, fast testing, long battery life, and easy operation.
