PowerTitan 3.0

HEFEI – October 21, 2026 -- Sungrow's PowerTitan 3.0 battery energy storage system contained a thermal runaway event that reached 1259.8°C without spreading to adjacent containers or a medium-voltage substation, becoming the first stacked-cell BESS with an AC-block design to complete a large-scale fire test under UL 9540A: 2026 and CSA/ANSI C800-2025.

UL Solutions conducted the test. Fire Risk Alliance witnessed it and Jensen Hughes observed it. All three PowerTitan generations, 1.0 through 3.0, passed their large-scale fire tests on the first attempt.

Test layout replicated a utility-scale installation with 28.56 MWh of storage

The setup mirrored a block-level utility-scale layout. It included 28.56 MWh of fully liquid-cooled PowerTitan 3.0 units and a 7.4 MW medium-voltage substation. PowerTitan 3.0 combines stacked high-energy-density cells and the DC/AC power converter unit in a single 20-foot container.

Munich – – September 30, 2026 -- Germany's day-ahead power prices spiked to around €210/MWh during summer heatwaves this year, levels typically seen only in winter, according to LSEG data cited by Reuters, even as the same market recorded 573 hours of negative wholesale prices in 2025.

Heat and oversupply pushed Europe's power market to opposite extremes within hours

Rising cooling demand collided with reduced nuclear output caused by high river temperatures and low water levels, while weak wind conditions and lower thermal efficiency tightened supply further. Hours later, the same grids faced the reverse problem: too much electricity. The International Energy Agency found negative-price hours accounted for roughly 6% of the year in 2025 across Germany, France, Spain and the Netherlands.

Munich and Oldenburg, Germany – September 19, 2026 -- Sungrow Deutschland GmbH and be.storaged GmbH have signed a framework agreement to jointly deliver battery energy storage system (BESS) projects with a planned pipeline of 1.6 GWh over the next two years in Germany.

Framework agreement standardizes gigawatt-hour scale storage delivery

The deal extends an existing partnership between the two companies, setting standardized processes, coordinated technical solutions, and early joint planning to accelerate project execution and cut coordination requirements. Dr Magnus Pielke, Managing Director of be.storaged, said the agreement establishes a long-term partnership enabling both firms to standardize BESS projects at gigawatt-hour scale and respond faster to regulatory changes.

Mexico City – September 10, 2026 -- Sungrow will convene two flagship Latin America energy summits this fall, gathering government officials, utilities, EPCs, and developers to address grid modernization and storage deployment across the region.
