As Europe’s energy transition accelerates, the momentum of renewable energy continues to surge. From March 3 to 6, SAJ made consecutive appearances at three top-tier energy exhibitions: Green Energy Expo Romania, Key Energy Italy, and ENEX 2026 Poland. Spanning key markets in Eastern and Southern Europe, SAJ showcased its full-range exhibition layout and robust product portfolio, demonstrating its firm commitment to the European market. As a standout Chinese brand driving Europe’s energy transition, SAJ perfectly embodies the promise: Where there is energy demand, there is SAJ.
Strategic Penetration into Core European Markets
01 Green Energy Expo, Bucharest, Romania (Mar 3–5)
Green Energy Expo marked a key milestone for SAJ to officially deepen its presence in Central and Eastern Europe (CEE) and the Balkan region. As a professional exhibition focusing on renewable energy, energy storage, and smart transformation, the event gathered industry leaders across the entire value chain.
SAJ presented its residential solutions including H2, HS3, commercial & industrial (C&I) flagship models CHS2, CM2, and the intelligent energy management platform elekeeper. By delivering region-adapted energy solutions and engaging with local partners, SAJ accelerated its penetration into the residential and C&I energy storage markets.
02 Key Energy, Rimini, Italy (Mar 4–6)
A flagship barometer of energy transition in Southern Europe, North Africa, and the Mediterranean, Key Energy attracted over 500 top buyers from 57 countries and regions. SAJ emerged as a highlight among Chinese energy storage brands.
At the show, SAJ launched its new C&I storage inverter CH3, showcased the classic CM2, and displayed the residential dual flagship HS3 and new H3, supported by the elekeeper platform. This combination of mature and innovative products perfectly matched local demand for high-efficiency, reliable energy storage solutions, further strengthening SAJ’s influence in Southern Europe and expanding global cooperation.
03 ENEX 2026, Kielce, Poland (Mar 4–5)
ENEX 2026 brought together nearly 300 enterprises from 11 countries and over 22,000 professional visitors, serving as a premier platform for energy trends and core resources in Central Europe.
SAJ exhibited C&I storage solutions CM2, CHS2, residential models HS2 and new H3, and the intelligent platform elekeeper. Its integrated energy solutions drew strong industry attention. During the exhibition, SAJ co-hosted a gala dinner with local partner OSW, inviting installers and key clients to further strengthen partnerships and lay a solid foundation for long-term development in Central Europe.
Powerful Product Portfolio Empowering Global Energy Transition
