On June 23, the opening day of The smarter E Europe 2026, Deye was officially awarded several prestigious certifications by TÜV Rheinland, the world’s leading third-party testing, inspection, and certification organization. The certifications cover a diverse range of Deye’s flagship products: 100-125kW C&I Three-Phase HV Hybrid Inverter achieved EN 50549-2 certification; New SG06 Series 3-6kW Residential Single-Phase LV Hybrid Inverter attained the German certification; 5MWh Utility-Scale Liquid-Cooled Energy Storage Solution secured TÜV Mark and CE-LVD certification. The certificate presentation ceremony was attended by Mr. Ji Dehai, Vice General Manager of Ningbo Deye Technology Corporation and R&D Director of Deye Inverter; Mr. Luxin Liu, General Manager of Ningbo Deye ESS Technology Co., Ltd.; and Mr. Weichun Li, Senior Vice President of Solar & Commercial Products, Greater China, and Senior Vice President of Global Power Electronics Products at TÜV Rheinland Group. These certifications mark a significant step in Deye's compliance strategy in the European market, providing a robust technical foundation for its global expansion and large-scale deployment. 

As the global energy transition accelerates, the safety and grid-connection reliability of PV and energy storage products have become increasingly critical. The certified hybrid inverters and 5MWh Utility-Scale Liquid-Cooled ESS Solution, span distributed residential, C&I, and large-scale centralized applications： 

• 100-125kW C&I Three-Phase Hybrid Inverters: Engineered for demanding commercial and industrial applications, this series offers exceptional scalability and grid compatibility, enhancing energy resilience for businesses facing grid fluctuations. The EN 50549-2 certification validates its performance in grid compliance, power stability, and safety, meeting the stringent standards of European medium-voltage grids.
• 3-6kW Residential Single-Phase Hybrid Inverters: Featuring a compact, high-power-density design, this series delivers maximum performance within limited installation spaces, seamlessly integrating into modern homes. Securing the German certification grants this series official market access in Germany and across Europe, establishing it as a quality-assured, sustainable solution for residential users.
