Next-generation AC block energy storage system

For the North American market, Sungrow’s PowerTitan 3.0 delivers 6.9MWh in a standard 20ft ISO container, integrating batteries with the string PCS for 2–8 hour designs. It features a mass-produced 661Ah stacking LFP cell, with a 12,500-cycle lifespan for reliability and cost efficiency. The system debuts a 430kVA liquid-cooled SiC PCS, achieving up to 99.3% maximum efficiency and up to 93.6% RTE for a 4-hour duration (92% including auxiliary load). Five-level SOC balancing maximizes usable capacity, while a back-to-back layout reduces footprint. And robust liquid-cooled thermal management reduces auxiliary power use and extends system lifespan. Safety is prioritized with 11-layer protection from cell Over-Voltage to PCS AC fusing, and Sungrow’s ArcDefender™ technology to reduce arcing risks. The system meets all Authority Having Jurisdiction (AHJ) requirements in North America thanks to its fire safety systems, and is fully pre-tested and certified. The PowerTitan 3.0 is engineered for rapid deployment. The system comes fully UL9540-certified before shipment. Enhanced on-site O&M tools further shorten commissioning timelines compared to the previous product generation. Embedded with Sungrow’s Stem-Cell Grid-Forming Tech 2.0, the PowerTitan 3.0 anticipates grid disturbances before they escalate, ensuring energy storage responds proactively.
