Recently, the Max-Pro liquid-cooling commercial and industrial energy storage cabinet, independently developed by TWS Technology, successfully passed the tests of grid-connected energy storage core safety standard of IEC 62933-5-2:2020. The tests were conducted by the internationally renowned certification body SGS. This significant milestone signifies that Max-Pro has reached the world's top level in terms of safety, reliability, and grid compatibility. It will provide global commercial and industrial customers with more trustworthy clean energy storage solutions and lays a solid foundation for the company's further expansion in the global C&I energy storage market.

The IEC 62933 series of standards are core safety specifications specifically formulated by the International Electrotechnical Commission (IEC) for energy storage systems and are widely recognized globally. The IEC 62933-5-2:2020 standard, which applied in this testing, focuses on the safety requirements of grid-connected energy storage systems. The tests cover critical dimensions including electrical safety, battery system safety, environmental adaptability, and functional safety. They impose stringent requirements for all aspects of the entire lifecycle of an energy storage system – from design and manufacturing to installation, operation, and fault response – aiming to ensure product stability and reliability during grid interaction. Renowned for its rigor and independence, SGS's testing and certification serve as a strong endorsement of product safety and quality.

The Max-Pro ESS cabinet integrates TWS Technology's cutting-edge technologies. It is specifically designed to meet the energy storage needs of commercial and industrial users under high-load, long-cycle, and demanding environment. It boasts advantages including high efficiency and flexibility, safety and reliability, convenient installation, and smart friendliness. Equipped with a built-in PCS, Max-Pro achieves an integrated AC/DC design, saving floor space, significantly simplifying on-site installation and commissioning, reducing after-sales maintenance, and enhancing project safety, efficiency, and cost-effectiveness. Max-Pro employs advanced liquid cooling technology to effectively control battery temperature, ensuring stable system performance under various operating conditions, thereby greatly enhancing the safety and reliability of the energy storage system. It integrates multi-level safety protection mechanisms, including gas fire suppression and liquid fire suppression facilities. An intelligent thermal runaway early warning and suppression system monitors battery status in real-time, enabling rapid intervention upon detecting abnormalities to prevent the occurrence and spread of thermal runaway. Comprehensive electrical protection safeguards all electrical connection points to avoid safety incidents caused by electrical faults. Furthermore, its optimized design delivers higher energy density, allowing the deployment of larger-capacity energy storage systems within limited spaces, thereby reducing customer land costs. The modular architecture supports on-demand configuration and seamless future expansion, catering to the evolving energy needs of businesses. This results in a lower Levelized Cost of Energy (LCOE) over the system's lifecycle and a superior return on investment.

Successfully passing the IEC 62933 tests conducted by SGS means that Max-Pro can effectively ensure the safe operation of the system, mitigate potential risks, and provide users with reliable energy storage solutions in complex grid environments. This achievement is the result of TWS Technology's relentless pursuit in the fields of energy storage safety and technology. It not only reflects the foresight of TWS Technology's R&D capabilities but also demonstrates the company's compliance management capabilities in the global market and its commitment to fulfilling safety promises to customers. Building on this foundation, TWS Technology will continue to uphold the philosophy of technological innovation, remain customer and market-oriented, persistently invest in R&D, and continuously enhance product performance and quality, providing more innovative and reliable energy solutions for the global commercial and industrial energy storage market, empowering customers worldwide in their energy transition, and jointly advancing towards a sustainable future.
