Sungrow's Major Achievement in Energy Storage Compliance

Sungrow, a global leader in renewable energy technology, has recently achieved a significant milestone by becoming the first company in the world to pass the Notified Body (NB) assessment under the European Union Battery Regulation 2023/1542. This native achievement validates Sungrow's full portfolio of Energy Storage Systems (ESS), encompassing commercial, industrial, and residential applications, reinforcing their regulatory compliance in a stringent market landscape.

The Context of the EU Battery Regulation

The EU Battery Regulation is recognized as the first comprehensive regulatory framework that governs the entire lifecycle of battery systems—from production and operation to reuse and recycling. Encompassing nearly 100 provisions and multiple annexes, the regulation seeks to establish unified requirements that promote environmental responsibility and consumer safety. As it gradually rolls out more stringent standards, it significantly impacts manufacturers worldwide, making compliance imperative not only for entry into the EU market but also influencing access to other high-standard global markets.

Key Assessment Criteria

The assessment, conducted by TÜV Rheinland (No. 1008), focused on several critical technical provisions that are already in effect. These provisions included:

• - Restrictions on Hazardous Substances: Ensuring materials used in storage systems are safe for the environment and users.
• - Performance and Durability: Establishing standards that guarantee reliability and longevity.
• - Safety Requirements: Addressing the safety of energy storage systems in stationary battery applications.
• - Labeling Obligations: Mandating clear markers for users to understand the product's specifications.
• - Battery Management Parameters: Evaluating metrics such as State of Health (SOH) and expected lifespan for effective monitoring.

TÜV Rheinland's assessment approach included compliance verification through Module D1, which comprises quality management system audits and ongoing oversight to ensure adherence to standards.

Sungrow's Compliance Confirmation

In the successful evaluation, TÜV Rheinland confirmed that Sungrow’s major products, including the PowerTitan for large-scale applications, the PowerStack and PowerKeeper for commercial and industrial uses, as well as all residential battery series, have met and exceeded the required regulatory criteria. Bowen Dong, General Manager of PV ESS Product Services at TÜV Rheinland Greater China, praised Sungrow's dedication to safety design and system reliability, stating that their solutions comprehensively comply with the stringent EU Battery Regulation requirements. Sungrow’s accomplishment serves as a benchmark for the industry in navigating the evolving regulatory landscape in Europe.

Sungrow's Commitment to Sustainability

Operating for over 29 years, Sungrow has pioneered innovations in clean energy solutions. As of December 2025, it had globally installed over 1,000 GW of power conversion equipment and is recognized as the most bankable company in photovoltaic inverters and energy storage (BloombergNEF). Their continuous innovations are underpinned by a robust service network of 520 service centers, which ensure exceptional customer experience. Sungrow remains dedicated to advancing a sustainable future through state-of-the-art technologies and unmatched service performance.

In conclusion, Sungrow’s successful navigation of the EU's rigorous assessment not only enhances its reputation but also sets a high standard for energy storage systems globally, paving the way for further innovations and compliance in the renewable energy sector.
