In the rapid evolution of the global photovoltaic industry towards high efficiency and high power, double glass modules have become the mainstream choice for photovoltaic power plant construction due to their excellent double-sided power generation performance, high durability, and long lifespan advantages. However, traditional IV testers generally suffer from pain points such as insufficient range, poor compatibility of double glass components, poor detection accuracy, and cumbersome operation. Especially in high-power double glass component and string testing, the conventional range of 1000V/20A is difficult to meet the requirements, resulting in low acceptance efficiency of power plants, high operation and maintenance costs, and difficult to accurately guarantee power generation revenue. To solve the core problems in the industry, LAILX New Energy Technology Co., Ltd. in Suzhou has been deeply involved in the field of photovoltaic testing for many years. With profound technical accumulation and continuous innovation capabilities, it has launched the LX-PV33 portable IV tester, which redefines the photovoltaic IV testing standard with a 2000V ultra-high voltage range, 40A high current testing capability, dual glass exclusive detection algorithm, and lightweight portable design, providing efficient, accurate, and reliable integrated testing solutions for the entire photovoltaic industry chain.

As the flagship photovoltaic performance testing equipment of LAILX, LX-PV33 has been focusing on the pain points of double glass module testing since its development, achieving multiple core technological breakthroughs. In terms of range configuration, the equipment is equipped with LAILX's latest resistive testing module, with a voltage testing range covering 0-2000V and a current testing expansion to 40A, perfectly solving the problem of limited range of traditional equipment. It can accurately complete IV curve testing and series parallel performance testing of high-power double glass components, half piece components, and string components, and is fully compatible with current mainstream high-efficiency photovoltaic module specifications. In response to the detection error caused by the double-sided power generation characteristics of double glass components, LX-PV33 has a built-in multi irradiation algorithm and component correction database, which can automatically correct and shield the interference of back panel electrical energy, independently calculate the power generation efficiency and STC conversion value of the front solar cells, and complete accurate detection without covering the back of the photovoltaic panel, completely breaking the limitations of traditional equipment detection and greatly improving the detection efficiency and accuracy of double glass components.

The core competitiveness of IV testers lies in their detection accuracy and stability. LX-PV33 strictly follows authoritative domestic and international standards such as IEC 61215, IEC 61646, GB/T 19064, etc. The voltage testing accuracy reaches ± 0.5% ± 0.2V, the current testing accuracy reaches ± 0.5% ± 0.02A, and the maximum power testing repeatability accuracy is ± 0.5% ± 3W. It can accurately capture the current voltage characteristic changes of photovoltaic modules under different working conditions, accurately identify hidden defects such as cracks, hot spots, diode faults, etc., and provide reliable data support for component quality judgment and power station operation and maintenance optimization. At the same time, the equipment adopts industrial grade anti-interference design, which can operate stably in complex electromagnetic environments, high and low temperatures, and humid conditions, adapt to various harsh working scenarios of outdoor photovoltaic power plants, and ensure the authenticity and effectiveness of detection data.

In terms of portability and operability, LX-PV33 fully meets the needs of outdoor testing, with a total weight controlled within 6kg. It is equipped with a high-strength protective chassis that is shockproof, dustproof, and waterproof, making it easy to carry and transport. A single person can easily complete equipment handling and operation, completely eliminating the dependence of traditional large equipment on site and manpower. The device is equipped with a 640 * 480 high-definition touch display screen and a bilingual Chinese/English operation interface. The interface is simple and intuitive, and the operation process is simplified. It can be quickly mastered without professional training, and the IV curve test of a single component or string can be completed within 30 seconds, greatly improving the detection efficiency. In addition, LX-PV33 supports real-time data storage, historical data query, report export, and USB data transmission. It can be integrated with computer software for in-depth data analysis, providing data support for the full lifecycle management of power plants and helping photovoltaic power plants achieve refined operation and maximize profits.

Since its launch, the LX-PV33 portable IV tester has been widely used in large-scale ground power stations, distributed photovoltaic power stations, component production enterprises, third-party testing institutions, and other scenarios. With its core advantages of ultra large range, high precision, and strong portability, it has gained high recognition from industry users. In the future, LAILX in Suzhou will continue to deepen its research and development of photovoltaic detection technology, continuously optimize product performance, empower the high-quality development of the photovoltaic industry with innovative technology, and provide higher quality and more efficient detection solutions for global photovoltaic users.
