PowerTitan 3.0 Energy Storage System
Overview
Sungrow's utility-scale storage platform and the product that put it top of the global integrator rankings. Three container sizes cover the range: Flex at 3.45 MWh in 10 feet, Class at 6.9 MWh in 20 feet, and Plus at 12.5 MWh in 30 feet, the largest BESS container in the world by capacity and energy density, cutting land footprint by 45%. The platform uses up to 684 Ah stacked cells and the first large-scale fully liquid-cooled silicon-carbide power conversion system, hitting 99.3% peak efficiency and supporting 2 to 12 hour durations. The grid-forming version launched in Europe in January 2026 adds 20-millisecond reactive power response, microsecond voltage construction and gigawatt-scale black start, at 7.2 MW / 28.5 MWh per AC block and 92% round-trip efficiency.
Shipping globally since mid-2025; grid-forming European variant launched January 2026, part of 43 GWh shipped in 2025 and a >60 GWh target for 2026
