On June 3, the first day of SNEC 2026, Wolong Energy Storage responded to this industry shift with two strategic moves:

First, it received TÜV NORD IEC certification for its 3MWh liquid-cooled energy storage system, validating its international compliance and technological depth.

Second, it held nine strategic signing ceremonies with 10 industry-leading enterprises, including Jiangsu Keneng, Shanghai Electric, and Towngas Energy, further expanding its ecosystem footprint.

Key highlights:

The certified WL-ESS-1152kW/3086kWh-400V system features 314Ah cells, 3,086kWh energy capacity in a standard 20-ft container, IP55/IP66 protection, UL9540A compliance, and wide-temperature operation (-20°C to 50°C), with adaptability for high-altitude environments up to 3000 meters.

The nine partnerships span engineering consulting, regional planning, renewable energy development, utility and C&I applications, system integration, power electronics, energy services, core equipment manufacturing, and battery cell supply.

With full-stack capabilities across supply chain, manufacturing, market, and service, Wolong Energy Storage is evolving from a hardware provider into an ecosystem builder — contributing to a new phase of the energy storage industry: from product export to standard export, and from single equipment to system-level solutions. SNEC 2026 is still ongoing, and more exciting highlights from Wolong Energy Storage are yet to come.
