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 presented a comprehensive portfolio of full-scenario energy storage solutions covering residential, commercial and industrial (C&I), and utility-scale applications.
On the opening day, SVOLT signed a number of strategic cooperation and supply agreements representing more than 8 GWh of cumulative capacity. The agreements reflect growing market recognition of the company’s latest developments in energy storage safety, system integration, and operational efficiency.
At SNEC 2026, SVOLT showcased multiple variants of its signature 122 Ah stacked residential energy storage cell, which has already entered the global Top 5 supply chains and achieved GWh-scale deliveries. The product platform now includes a Fast-Charging Edition and a Low-Temperature, Long-Life Edition. The two variants are designed to address different residential energy storage requirements, including higher charging efficiency and more reliable operation in cold climates.
SVOLT’s 285 kWh C&I all-in-one System is powered by its 371 Ah 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.
The system incorporates an advanced dual-side liquid cooling technology, which narrows cell-to-cell temperature differentials and extends the total system lifecycle by approximately 10%. Its AI-BMS (artificial intelligence battery management system) dynamically optimizes charging and discharging strategies and can improve O&M (operations and maintenance) efficiency by up to 60%, subject to the applicable operating and evaluation conditions. With an ambient operating temperature range of -30°C to 55°C, the system is designed for applications including industrial and commercial facilities, time-of-use energy arbitrage, peak-demand management, and demand-charge reduction.
SVOLT’s flagship 6.29 MWh utility-scale ESS container utilizes its 371 Ah stacked short-blade cells, each providing a nominal energy of 1,187 Wh. The cells are designed to deliver more than 10,000 cycles under specified operating and test conditions. The module-free cell-to-rack architecture reduces structural component count by 36% and improves space utilization by 20% compared with the conventional module-based architecture.
The system uses a three-compartment isolation design that physically separates the battery, electrical equipment, and liquid-cooling sections. Thermal-electrical separation directed gas venting, and a three-tier fire protection system provides multiple layers of protection from the cell level through to the complete system. Under the specified operating conditions, the thermal-management design reduces the maximum cell temperature spread from 7°C to 15°C. This improvement supports greater operating consistency, longer system life, and a lower levelized cost of storage.
Together, the 122 Ah residential cell platform, the 285 kWh C&I system, and the 6.29 MWh utility-scale container demonstrate SVOLT’s strategy of applying stacked-electrode technology and highly integrated system design across multiple energy storage scenarios.
