Sixty-six sets of Sungrow’s PowerTitan 2.0 energy storage system have arrived in the UK, underlining the acceleration of energy storage deployment in Europe. Beyond Europe, in the Middle East over 1,500 sets of the product are set for deployment, while in Asia, multiple PowerTitan 2.0 based projects have already been successfully commissioned, showcasing impressive performance in cost reduction, safety and grid forming. The product is rapidly gaining traction worldwide, effectively spearheading the energy storage industry’s transition into the AC Block era.
What is the AC Block?
PowerTitan 2.0 introduces the revolutionary AC Block, which integrates a 5 MWh battery with a 2.5 MW PCS into a standard 20-foot container, a significant departure from the traditional method of separating direct current battery systems and alternating current PCS systems. This integration goes beyond just rearranging components; it involves efficiently combining the battery, PCS, fire suppression systems and other modules while pushing the boundaries of spatial design. According to a report by S&P Global Commodity Insight, only three companies worldwide, including Sungrow, currently provide authentic AC Block solutions.
Dr. James Li, Sungrow ESS Director for Europe, has stated that the success of PowerTitan 2.0 is significantly attributed to Sungrow’s fully self-developed PACK/BMS/PCS/EMS technologies, driving innovation through a foundational logic and holistic design approach. Moreover, PowerTitan 2.0 revolutionizes PACK structures and production processes, reducing the width of each PACK by 40mm for a more compact layout. Additionally, each cabinet houses 12 small standardized PCS units, matching the size specifications of PACKs for efficient space utilization. These benefits and innovations make the AC Block concept feasible.
With a more compact structure, increased heat dissipation challenges arise. PowerTitan 2.0 addresses this with a fully liquid-cooled solution for battery PACKs and PCS units, ensuring rapid heat dissipation and extending system longevity.
“In operational projects, PowerTitan 2.0 demonstrates its exceptional competitiveness,” commented Li. It saves 29% on land usage, requiring only 2000 square meters for a hundred-megawatt-hour system, significantly reducing land costs. The all-in-one AC-DC block design streamlines deployment with embedded PCSs, pre-assembled components, MVT, and comprehensive factory testing to reduce installation time onsite.
Thanks to its innovative AC-DC block design, PowerTitan 2.0 increases the system’s round-trip efficiency (RTE) by 2%, boosts the total discharge volume over the entire lifecycle by 8%, and reduces fault losses by 92%. Moreover, standardized short cable connections between batteries and PCS in a fully liquid-cooled cabinet, along with advanced AI-based battery health management and ArcDefender technology, effectively minimize thermal runaway and arcing risks, ensuring overall cabinet safety.
Looking ahead, with continuous product innovation and further cost reductions, AC Blocks represented by PowerTitan 2.0 will become the preferred choice for the energy storage market.
