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 revenue of power generation. However, traditional detection equipment generally suffers from practical pain points such as insufficient range, slow testing speed, large environmental interference, and poor outdoor portability. The market urgently needs a domestically produced IV detection equipment that balances high precision, strong portability, and intelligence. In this context, Shanghai LAILX closely follows the industry development trend and launches the LX-PV32 portable IV tester, providing a complete and reliable domestic solution for on-site performance testing of photovoltaics. Outdoor IV tester

LX-PV32 is designed specifically for mainstream 1500VDC high-voltage photovoltaic systems, with a voltage range covering 10V to 1500V and a maximum current of 20A. 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, etc. The equipment adopts self-developed high-precision load modules, with a voltage measurement accuracy of ± 0.5%. Even for old strings with weak performance degradation, it can accurately capture subtle changes in the curve. At the same time, the instrument is equipped with high-precision irradiance sensors and temperature sensing probes, relying on built-in algorithms to automatically correct the STC standard operating conditions of test data, eliminating data deviations caused by light fluctuations and temperature changes, and providing solid data support for power plant PR value accounting and power attenuation evaluation.

At the practical level of on-site operations, LX-PV32 has deeply optimized the portability of the entire machine. The total weight of the machine is less than 6kg, and it adopts an integrated compact body with a high-strength protective suitcase, which can be easily carried and quickly deployed by a single person. The device is equipped with a 6.5-inch high brightness color LCD touch screen, which is clear and visible under sunlight, and the operation logic is simple and intuitive. Equipped with a 14.8V high-capacity lithium battery, it can work continuously for more than 10 hours on a single charge, completely eliminating the limitations of traditional equipment being bulky and difficult to transport. Its testing efficiency is also outstanding, with a complete scanning and detection of a set of photovoltaic strings taking only about 10 seconds, greatly improving outdoor detection efficiency.

In terms of intelligence and data management, LX-PV32 has built-in intelligent algorithms that can automatically identify component specifications and string configurations, support custom testing parameters, and generate standardized reports. The device has an IP54 protection level, with a working temperature range of -10 ℃ to 50 ℃, and is not afraid of harsh outdoor environments. The test data can be exported through a USB flash drive or connected to a computer via Bluetooth, and combined with specialized analysis software to achieve curve comparison and fault diagnosis. The launch of LX-PV32 not only fills the market gap of 1500V high-voltage portable IV detection, but also becomes the preferred equipment for EPC acceptance and operation inspection of photovoltaic power plants with the core values of "high precision, fast testing, long endurance, and easy operation", helping the global photovoltaic industry to develop with high quality and safety.
