From June 3 to 5, the 19th SNEC International Solar Photovoltaic and Smart Energy (Shanghai) Exhibition successfully concluded at the National Exhibition and Convention Center. As a global benchmark for the solar and energy storage industry, this year’s event brought together thousands of enterprises from around the world, with intelligent energy storage testing, system auxiliary equipment, and overseas market expansion emerging as key industry hotspots. Zhuhai Jiuyuan Power Electronic Technology Co., Ltd. (Booth E115) made a strong impression by showcasing its core products, including the energy storage back-to-back power router and the energy storage EOL tester. The company received a large number of domestic and international visitors and reached multiple cooperation intentions, steadily advancing its global business.
Leveraging over a decade of expertise in power electronics, the company focuses on two major areas: battery and energy storage production line testing, and system interconnection auxiliary equipment. It develops highly stable and adaptable professional devices that fully meet the testing needs of energy storage battery packs, modules, and complete packs throughout production and maintenance. The main products exhibited this year precisely addressed industry pain points in production and system networking, earning high recognition from on-site customers.
The booth highlighted two core product lines:
1. Energy Storage EOL Tester
As a key piece of equipment for full-performance testing at the end of energy storage production lines, this tester integrates multiple test functions, including voltage, internal resistance, charge/discharge performance, and safety protection. It delivers high test accuracy and fast operation, ensuring comprehensive quality control of energy storage products before shipment. Suitable for mass production lines, it helps energy storage manufacturers achieve automated and standardized quality inspection.
2. 15MW Matrix Energy Storage Back-to-Back Power Router – MatrixLink-PST Series
This is a high-end test system designed for R&D and reliability verification of MW‑level energy storage systems. With a total test power of 15MW, it adopts a 4‑channel modular design (3.75MW per channel). The output voltage range is 0–1520V, with a per‑channel output current up to ±2500A. Voltage and current test accuracy reach ±0.05% FS, fully meeting the precision testing standards of high‑end energy storage products. The system integrates high‑precision DC/DC converters and bidirectional AC/DC converters, employing a common DC bus architecture. The overall system cycle efficiency is ≥98%, and with AC/DC staged energy recycling modes, it significantly reduces test energy consumption and electricity costs. Featuring anti‑interference capability, stable operation, and easy deployment, it is widely used in large‑scale energy storage power stations and industrial/commercial energy storage projects, effectively enhancing the overall coordinated operation of energy storage systems.
During the exhibition, professional visitors from Europe, Southeast Asia, Latin America, and other regions visited the booth for in‑depth discussions on product performance, customization solutions, overseas certifications, and lead times. Several overseas distributors and energy storage integrators signed strategic cooperation agreements and intended purchase orders with the company, further expanding its overseas sales channels.
A representative from Zhuhai Jiuyuan stated that SNEC is an excellent platform for connecting with global resources and demonstrating technical strength. Going forward, the company will continue to refine its energy storage testing and auxiliary equipment, persist in technological innovation and quality upgrading, optimize product solutions based on market needs in different overseas regions, expand global partnerships, and contribute to the high‑quality development of the solar and energy storage industry with solid products, working together with all partners to build a green energy ecosystem.
