On March 4, 2026, Wenergy showcased its latest battery energy storage systems (BESS) at ENEX 2026, one of the leading renewable energy exhibitions in Central and Eastern Europe. The company used the event to officially launch its Stars CL261 liquid-cooled C&I energy storage system, while announcing new strategic partnerships aimed at accelerating energy storage deployment across Europe.
The launch highlights Wenergy’s growing role in the Energy Storage Europe market, where demand for commercial and industrial energy storage (C&I ESS) continues to rise as businesses seek to integrate renewable energy and improve energy resilience.
Global Launch of the Stars CL261 Liquid-Cooled C&I Energy Storage System
The product launch opened with remarks from Susie Xu, Overseas Business Director of Wenergy, who emphasized the increasing importance of battery energy storage systems in enabling Europe’s clean energy transition.
Customer representative Piotr Sololowski then shared insights from ongoing energy storage collaboration with Wenergy, highlighting the reliability of the company’s C&I BESS solutions and the value of long-term technology partnerships.
The technical presentation was delivered by Senior Product Manager Starr. The liquid-cooled C&I ESS features a multi-layer safety architecture including ceramic insulation between cells, dual-level aerosol fire suppression, explosion-proof ventilation, and continuous BMS monitoring. With optimized thermal management and high-efficiency PCS integration, the system achieves over 90% round-trip efficiency while reducing installation footprint by 36%, making it well suited for commercial and industrial sites with limited space.
Project examples presented during the session demonstrated how Wenergy’s BESS technology supports applications such as peak-valley energy arbitrage, grid services participation, and renewable energy integration across international markets.
Full-Scenario Energy Solutions Powered by EMS
Wenergy also highlighted its Energy Management System (EMS) platform, which acts as the intelligent control layer for C&I energy storage systems. The EMS enables advanced operational strategies including electricity price tracking, peak-valley optimization, demand control, PV self-consumption, and off-grid operation, helping commercial users maximize the value of PV + storage systems.
During the event, Mieszko Stubinski, a regional partner of Wenergy, shared real-world project insights demonstrating how the EMS platform supports localized energy management. One example featured a bus charging station in Poland, where solar energy stored during the day is discharged at night to power electric buses, significantly reducing grid electricity costs while supporting cleaner public transport.
Strategic Partnerships Accelerate Energy Storage Growth in Europe
ENEX 2026 also provided the stage for Wenergy to sign strategic cooperation agreements with multiple energy companies across Poland and Central & Eastern Europe. The partnerships will focus on joint project development, localized technical services, and market expansion for commercial and industrial BESS solutions.
With established offices, service networks, and regional warehouses across Europe, Wenergy continues to strengthen its local presence and customer support capabilities.
By combining advanced liquid-cooled energy storage technology, intelligent EMS platforms, and global project experience, Wenergy aims to accelerate the adoption of safe, efficient, and scalable energy storage solutions across the European energy storage market.
