Recently, Suzhou LAILX New Energy Technology Co., Ltd. (LAILX) has launched the LX-PV31 portable IV tester, which combines high precision, high efficiency, and portability. The advent of this product not only fills the gap in the industry's mid-to-high-end portable IV testing equipment segment, but also provides a new solution for photovoltaic module testing, power station operation and maintenance, and third-party testing through multiple core technological breakthroughs, thereby contributing to the high-quality development of the photovoltaic industry.

With the rapid iteration of the global photovoltaic industry, the demand for testing the power generation efficiency and stability of photovoltaic modules is becoming increasingly stringent. Traditional testing equipment faces pain points such as insufficient measurement range, cumbersome operation, low testing efficiency, and poor outdoor adaptability, making it difficult to meet the diverse needs of large-scale photovoltaic power station operation and maintenance, module production quality inspection, and third-party testing. Suzhou LAILX has been deeply involved in the field of photovoltaic testing for many years. Relying on its core technological research and development strength, it has specifically addressed industry pain points and launched the LX-PV31 portable IV tester. With "precision, efficiency, convenience, and versatility" as its core positioning, it redefines the standard for portable IV testing.

As a standard IV curve tester for photovoltaic modules, the LX-PV31 achieves multiple breakthroughs in core performance. This device can accurately detect the power generation efficiency and conversion rate of components and strings within a voltage range of 1500V, expanding the test range to 30A, effectively solving the problem of insufficient range in mainstream markets at 1000V and 20A. It is particularly suitable for measuring the operating current of half-cut components at around 20A, matching over 95% of current photovoltaic panel specifications, and demonstrating strong adaptability. In terms of detection accuracy, the device utilizes the latest resistive test module, equipped with high-precision capacitive/resistive loads, achieving voltage and current test accuracies better than 0.2%. It has been authoritatively verified by the National Institute of Metrology, China, and can serve as a third-party metrology basis. Additionally, it is equipped with a rapid irradiance meter operation module and IV curve analysis software, supporting a high-resolution test mode with up to 400 points, enabling clearer analysis of the IV curve and precise capture of component performance details.

Efficiency and convenience are another core highlight of the LX-PV31. The device adopts integrated packaging technology, featuring a compact and lightweight body weighing less than 6kg and measuring only 390*300*200mm. Operation and maintenance personnel can easily navigate between photovoltaic arrays with one hand, adapting to complex operational scenarios such as rooftops and mountains without the need for additional equipment handling. In terms of operation, the device is equipped with a 6.5-inch color LCD touch screen, supporting a bilingual (Chinese and English) operation interface with clear and easy-to-understand function descriptions, enabling even novice operators to quickly get started. It is equipped with one-button detection and data export functions, with a detection speed of just 10 seconds for a single module/string, significantly improving efficiency compared to traditional devices and greatly reducing the detection time for large-scale photovoltaic power stations. Additionally, the device has a built-in high-capacity replaceable lithium battery module, providing up to 8 hours of continuous operation on a single charge, perfectly solving the problem of insufficient power supply for outdoor operations.

In terms of functional adaptability and safety assurance, the LX-PV31 performs equally well. This device covers all-scenario requirements, including single-module testing, string testing, irradiation testing, and power generation testing. It can accurately measure multiple key performance indicators such as shadow obstruction, dust attenuation, fill factor, maximum power, and conversion efficiency. It supports the conversion of STC standard test conditions and can automatically calculate the true power generation efficiency of solar panels, helping users accurately grasp the operating status of components. Additionally, the device features a component barcode scanning function, enabling automatic matching of detection data with component barcodes for traceability and querying. It supports continuous testing and can be set to automatically detect at 20-second intervals, enabling continuous monitoring and comparative analysis of component performance. In terms of safety design, the device adopts a high-voltage isolated power supply design, featuring automatic range switching and triple protection mechanisms against overvoltage, overcurrent, and temperature. It complies with multiple international and industry standards such as IEC 61215-2005 and GB4793.1-2007, and has passed CE and ROHS certifications, providing dual protection for operator and equipment safety.

The relevant person in charge of LAILX in Suzhou stated that the launch of the LX-PV31 portable IV tester is a significant achievement of the company's deep exploration in the field of photovoltaic testing and its practice of the concept of "empowering industry with technology". Relying on domestic core configurations and international standard quality, the equipment not only possesses high-precision and high-efficiency detection advantages, but also provides gold-level services such as 24-hour rapid after-sales service and free software and hardware upgrades. It can be widely applied in various fields such as photovoltaic module production quality inspection, power station operation and maintenance, third-party testing, scientific research and experimentation. It can not only help enterprises reduce testing costs and improve operation and maintenance efficiency, but also provide data support for the standardized and efficient development of the photovoltaic industry.

Currently, the photovoltaic industry is moving towards large-scale, high-efficiency, and intelligent development. The upgrading and iteration of testing equipment serve as crucial support for the industry's high-quality development. Suzhou LAILX will leverage the opportunity presented by the LX-PV31 portable IV tester to continuously increase R&D investment, focus on industry needs, and launch more innovative and practical photovoltaic testing equipment. This will help China's photovoltaic industry gain an advantage in global competition and promote the sustainable and healthy development of the green energy industry.
