Sungrow has launched PowerStack 255CS, its next-generation liquid-cooled commercial and industrial (C&I) energy storage system, designed to redefine efficiency, safety and convenience and accelerate the global energy transition.
The installed capacity of C&I energy storage is expected to reach 46GWh by 2028, with businesses worldwide turning to C&I ESS to reduce energy consumption, lower electricity costs, enhance power supply reliability and support the integration of renewable energy. However, the rapid energy transition requires innovative storage solutions to tackle pressing challenges such asunstable power supply and grid pressurefrom growing demands of EV charging.
Equipped with 314Ah battery cells, the PowerStack 255CS delivers a 257kWh capacity (2-hour system) or 514kWh capacity (4-hour system) for a single container, the system ensuring a round-trip efficiency (RTE) of more than 90% and a product design lifetime of up to 20 years.
Incorporating advanced liquid-cooling technology, the AI-controlled heat balance technology analyzes cell temperature and operating conditions data, intelligently adjusting the cooling power to reduce auxiliary power consumption by 33% – maximizing both performance and economic benefits.
The product meets top-tier global safety certifications, including UL9540 and NFPA855/69/68/14, ensuring the highest standards of protection.
With a fully integratedEnergy Management System (EMS), Power Conversion System (PCS), and Battery Management System (BMS), PowerStack 255CS streamlines energy storage operations while reducing installation complexity. The system supports multiple layout configurations, offering adaptable deployment for diverse site requirements. Pre-installed and pre-commissioned components enable rapid grid connection, enhancing overall efficiency.
Sungrow’s commercial and industrial products have already been deployed in over 1,000 projects worldwide, spanning various industries including metallurgy, automotive and textiles. The company’s solutions are widely used across Europe, as well as in Australia, Japan, the Middle East and South Africa.
