Since the implementation of the "dual carbon" target, the installed capacity of domestic photovoltaics has skyrocketed, and the scale of power stations has been expanding, but the operation and maintenance have become increasingly "complicated". When the industry shifts from "building fast" to "managing well", a simple contradiction emerges: what is the basis for judging string performance? For a long time, on-site testing has either relied on bulky laboratory grade equipment or hired third-party testing vehicles, resulting in a long cycle, high cost, and often being constrained by site and transportation conditions. The LX-PV32 portable IV tester launched by LAILX in Shanghai is aimed at this pain point - it compresses a set of "mobile laboratories" into a lightweight device that can be lifted with one hand.

LX-PV32 is designed specifically for the current mainstream 1500V DC high-voltage photovoltaic system, with a voltage range covering 10V-1500V and a maximum current of 20A. It is directly aimed at large string and high-voltage scenarios, integrating testing that used to require multiple devices and probes into one complete machine. It can measure a wide range of parameters, including I-V curve, P-V curve, short-circuit current, open circuit voltage, peak power and peak point voltage and current, constant voltage point current, fill factor, conversion efficiency, series resistance, parallel resistance, as well as environmental factors such as component temperature, ambient temperature, and irradiance - almost covering all key indicators required for string performance evaluation.

What truly sets LX-PV32 apart from traditional devices is the word 'portable'. The whole machine adopts an integrated industrial grade packaging, which is sturdy, durable, and has excellent protective performance, and can easily cope with complex outdoor work environments; The body is lightweight and small in size, paired with a dedicated portable case, allowing one inspector to easily carry it to any power plant site, completely eliminating the dependence of large testing equipment on site and transportation. In the past, string inspection, which often required lifting, vehicle allocation, and collaboration among multiple people, can now be completed by one person and one bag, achieving a qualitative leap in work efficiency and flexibility.

The operational aspect also takes into account 'people'. LX-PV32 is equipped with a fully Chinese visual operating system, with a simple and intuitive interface, clear functional zoning, and clear testing process guidance. Even frontline operations personnel who are new to it can quickly master it. The equipment is also equipped with testing probes for environmental temperature, solar panel temperature, irradiance detection, etc., which can fully record the environmental status during testing, making each test data "traceable and traceable", providing a solid basis for power plant acceptance, quality control, and later claims.

From the perspective of application scenarios, the value coverage of LX-PV32 is quite extensive: it can be used for acceptance testing by power plant construction units, supervision and sampling by quality inspection departments, factory sampling by component manufacturers, and experimental measurement by scientific research units to quickly and accurately understand the true working characteristics of the string under natural light. For EPC companies and operation and maintenance service providers, it means a more proactive quality control ability - sampling, on-site counting, on-site grading at any time, no longer passively waiting for external agencies to schedule.
At present, as photovoltaics move from scale expansion to refined operation and maintenance, the efficiency of detection tools is, to some extent, the quality of the "health check report" of power plant revenue. The LX-PV32, with a one handed device, has truly brought laboratory level testing capabilities to the field under sunlight, writing a lighter, faster, and more controllable new footnote for domestic photovoltaic quality inspection.
