The 2026 The smarter E Europe (TSEE) Munich, the global bellwether event for energy storage, has kicked off in full swing. As Europe’s largest and most influential professional energy storage exhibition, it gathers leading global energy enterprises to explore new opportunities for energy transition. At this year’s show, Wolong ESS unveiled two brand-new products: the 1 MW / 3 MWh AC/DC integrated ESS cabin and the 150 kW / 337 kWh commercial & industrial (C&I) energy storage cabinet. The booth also hosted an official IEC certification awarding ceremony and a strategic signing ceremony for two large-scale European energy storage projects. With competitive products, authoritative certifications and landmark orders, Wolong ESS has fully ramped up its market expansion campaign across Europe.
1. Global Launch of Two New Products, Covering Full Scenarios of Utility-Scale & C&I Energy Storage
At its Munich booth, Wolong ESS rolled out two benchmark products targeting utility-side and customer-side applications. Featuring high integration, superior safety and full compliance with European grid standards, the products precisely cater to diversified demands of Europe’s energy market.
1.1 1 MW / 3 MWh AC/DC Integrated ESS Cabin | Empowers Grid Connection of Large-Scale New Energy Power Stations
Developed to meet demand for large wind-solar bases, grid peak shaving and long-duration energy storage in Northern and Eastern Europe, the 1 MW / 3 MWh AC/DC integrated ESS cabin stands as the core flagship product at this exhibition. Already deployed for commercial operation in the Czech Republic, the product is fully adapted to the operating conditions of large European energy storage power stations.
1. High power density with transformerless topology
2. Full liquid cooling temperature control for long service life
3. Multi-tier comprehensive safety protection system
4. Modular plug-and-play design
5. Outstanding environmental adaptability
1.2 150 kW / 337 kWh C&I Energy Storage Cabinet | Optimal Choice for Distributed Energy Storage in European C&I Sectors
The newly launched 150 kW / 337 kWh C&I energy storage cabinet is tailored for European factories, industrial parks, commercial complexes and EV charging stations. It serves as a benchmark solution for distributed PV-storage integration, demand response and peak-valley arbitrage:
1. High-density integration with minimal footprint
2. High-efficiency transformerless topology with superior grid compatibility
3. Full-range liquid cooling for long-term stable operation
4. Multi-layer intelligent safety protection
5. Fast delivery and easy operation & maintenance
6. Robust weather resistance for all terrains
2. Backed by Authoritative Certification: On-Site IEC Award Ceremony Held for the 1 MW / 3 MWh AC/DC Integrated ESS Cabin
A highlight of the exhibition, the official IEC certification awarding ceremony for Wolong ESS’s 1 MW / 3 MWh AC/DC integrated ESS cabin was held at the booth. Mr. Alexander Ohff, Executive Vice President of Global Renewable Energy at TÜV NORD, attended the booth in person and presented the full set of IEC standard certification certificates to Wolong’s 3 MWh utility-scale energy storage product.
Supported by authoritative IEC certification, Wolong ESS can quickly participate in bidding for grid-side and new energy supporting energy storage projects across European countries, greatly shortening project approval cycles. The certification lays a solid technical compliance foundation for the implementation of European energy storage projects, and demonstrates Wolong ESS’s robust strengths in global product R&D and standardized manufacturing.
3. Two Large-Scale Overseas Energy Storage Projects Signed On-Site to Deepen Footprint in Europe’s Energy Storage Market
Following the certification ceremony, Wolong ESS held a strategic project signing ceremony. The two landmark European energy storage projects boast a total capacity exceeding 1,500 MWh, marking the official start of Wolong ESS’s large-scale product delivery phase in Europe.
3.1 Nordic NIEF 400 MW / 800 MWh Large-Scale BESS Project
The signed 400 MW / 800 MWh utility-scale energy storage project in the Nordics acts as a core supporting energy storage facility for local wind and solar power generation. It supports wind power consumption, grid frequency regulation and capacity reserve services in Nordic regions.
The Nordic region boasts abundant wind resources yet faces harsh low-temperature winters. Wolong ESS’s customized solutions will help the Nordics build a new energy power system and achieve regional energy independence and carbon neutrality targets.
3.2 185 MW / 740 MWh Energy Storage Project in Romania
The 185 MW / 740 MWh energy storage project in Romania is a key energy infrastructure initiative in Eastern Europe. It delivers multiple functions including PV supporting energy storage, peak load regulation and emergency grid backup.
Romania’s coastal areas suffer from salt spray corrosion and high summer temperatures. Wolong ESS’s products adopt anti-corrosion coating, IP55 full protection and multi-tier fire safety design, perfectly adapting to the complex local operating conditions.
The two projects have a combined capacity of over 1,500 MWh, covering two core European energy storage markets: Northern and Eastern Europe. This milestone signing fully recognizes Wolong ESS’s robust delivery capacity for large-scale overseas energy storage projects by the global market, and enables continuous expansion of its global energy storage business footprint.
4. Rooted in Munich: Wolong ESS Continues to Deepen Its Presence in Europe’s Zero-Carbon Market
As a core market for global energy transition, Europe faces surging demand for energy storage, with both utility-scale long-duration grid-connected storage and distributed C&I storage witnessing rapid simultaneous growth. Leveraging Wolong Group’s global industrial layout, Wolong ESS has built local teams covering technical support, sales and operation & maintenance, providing European customers with one-stop services including pre-solution design, on-site delivery and full-lifecycle operation & maintenance.
At this Munich exhibition, Wolong ESS delivered three core milestones: two new flagship products, authoritative IEC certification and two landmark overseas project signings, sending a clear signal to the global market:
1. Full-scenario product coverage: The product portfolio, ranging from the 150 kW / 337 kWh C&I energy storage cabinet to the 1 MW / 3 MWh AC/DC integrated ESS cabin, fully meets energy storage demands of utility-scale and C&I customer-side scenarios across Europe.
2. Globally compliant technology: Full set of IEC European standard certifications enable seamless compatibility with grid codes of all European nations.
3. Mature overseas delivery capacity: The signed 400 MW / 800 MWh Nordic and 185 MW / 740 MWh Romanian landmark projects fully validate global clients’ trust in Wolong ESS’s reliable delivery capabilities.
