At the International Photovoltaic Power Generation and Smart Energy Conference & Exhibition (SNEC 2026) held at the National Exhibition and Convention Center (Shanghai), SVOLT Energy Storage officially debuted its latest theme: “Stacking Era · The Ultimate Answers." The company showcased a comprehensive portfolio of full-scenario energy storage solutions covering Residential, C&I, and Utility-scale applications. On the opening day, SVOLT’s booth attracted global industry leaders and successfully closed multiple strategic partnerships and supply agreements, with a cumulative signed capacity exceeding 8 GWh. This milestone marks definitive global market validation for SVOLT’s iterations in high-capacity energy storage safety and efficiency.
122Ah Stacked Residential ESS: Platform-Based Design with Dual-Edition Flexibility
At SNEC 2026, SVOLT showcased multiple variants of its signature 122Ah stacked residential energy storage cell, an industry-leading product that has already entered the global Top 5 supply chains and achieved gigawatt-scale mass delivery. The highlight of this year’s exhibition is the evolution of the 122Ah cell from a single-specification product into a robust Platform-Based Solution. SVOLT now offers two specialized variations: the “Fast-Charging Edition" and the “Low-Temperature Long-Lifecycle Edition." This platform strategy flexibly satisfies the nuanced global demands for charging efficiency and cold-weather reliability across diverse household scenarios.
285kWh C&I Cabinet: Re-defining Commercial Storage Benchmarks via CTR Architecture
SVOLT’s 285kWh C&I All-in-One System is powered by its 371Ah thermal-composite stacked cells. Utilizing a module-less CTR (Cell-to-Rack) integration architecture, the system successfully reduces structural components by 36%, significantly enhancing structural rigidity and system stability. This innovative design positions the system as a key pillar in SVOLT’s full-scenario portfolio.
The system features an advanced dual-side liquid cooling technology, which narrows cell-to-cell temperature differentials and extends the total system lifecycle by approximately 10%. Additionally, the integrated AI-BMS (Artificial Intelligence Battery Management System) optimizes charge and discharge strategies in real time, boosting Operation & Maintenance (O&M) efficiency by up to 60%. With a wide operational temperature envelope spanning from -30°C to 55°C, the 285kWh C&I system excels in diverse applications including commercial parks, peak-valley arbitrage, and demand-charge management.
6.29MWh Utility-Scale ESS: Triple-Compartment Isolation Sets a New Baseline for 6MWh+ Safety
SVOLT’s flagship 6.29MWh Utility-Scale ESS Container features 371Ah stacked short-blade cells with 1,187Wh single-cell capacity and over 10,000 cycles of lifespan. Its module-less CTR architecture removes 36% of redundant components while improving space utilization by 20%.
The system incorporates a Triple-Compartment Isolation Design, separating battery, electrical, and liquid-cooling compartments, alongside thermal-electrical isolation, directional gas venting, and a three-level fire suppression system. These innovations reduce maximum cell temperature differential from 15°C to 7°C, enhancing thermal management, safety, and LCOS performance.
From its 122Ah Residential ESS and 285kWh C&I cabinet to the 6.29MWh utility container, SVOLT has validated its stacking technology through successful deployments and grid-connected projects across Europe, including Bulgaria and Moldova.
