[Suzhou, China, September 3, 2026] TÜV Rheinland hosted the 12th "All Quality Matters" Solar & ESS Summit and Award Ceremony in Suzhou. Nearly 200 leaders and experts from the PV & ESS industry gathered at the event. At this award ceremony, Huawei Smart String Residential ESS (LUNA2000‑S1) was granted the "Residential ESS Comprehensive Safety AQM Award." The LUNA2000-S1 delivers proven performance in cell-level thermal runaway non-propagation. It demonstrates outstanding safety design and robust technical strength, driving the PV & ESS industry toward higher safety standards and quality levels.
The "All Quality Matters" Award is a top honor in the PV & ESS industry. For 12 years, it has recognized exceptional quality and achievement. The award is based on TÜV Rheinland's rigorous testing standards and objective measured data, covering PV modules, solar and energy storage products, power plants, and the entire upstream and downstream supply chain. Using measured data as the criteria, it identifies quality benchmarks with long-term value in the market, Huawei Smart String Residential ESS (LUNA2000‑S1) has previously obtained the highest‑level Safety Mark certification from TÜV Rheinland and secured the world’s first highest‑level safety certificate in the residential energy storage sector.
Over the past 12 years, "All Quality Matters" has evolved from a single test report into an authoritative evaluation framework for the entire industry chain, and from an industry exchange event into a spiritual landmark of "winning by quality" for the PV & ESS industry. Grounded in a third-party neutral perspective, the award continues to drive the PV & ESS industry beyond homogenized competition and toward a path of high-quality development through technological innovation and value creation.
TÜV Rheinland Safety Mark certification consists of three levels:
Level 1: Basic Safety (Basic)
Meeting fundamental regulatory and standard requirements, Level 1 represents the baseline for market access and provides essential safety protection for ESS.
Huawei Residential ESS LUNA2000-S1 has passed the UL 9540A:2025 fire and explosion safety test, validating its reliable safety protection capabilities under thermal runaway scenarios. It also complies with the high-level functional safety requirements of ISO 13849-1:2023, enabling dual-redundant protection for critical safety functions and ensuring reliable system operation.
Level 2: Enhanced Safety (Plus)
Level 2 further enhances mechanical, electrical, thermal, and environmental protection capabilities, achieving no fire at the battery pack level during thermal runaway events.
Huawei Residential ESS LUNA2000-S1 adopts enhanced insulation protection design and complies with the IEC 62477-1 international electrical safety standard, significantly reducing leakage risks and preventing electric shock hazards to ensure all-weather household electricity safety.
Through multiple layers of safety protection, the system prevents fire and explosion at the system level under thermal runaway conditions, providing more reliable protection for households.
Level 3: Superior Safety (Prime)
As the highest-level safety certification, Prime requires ESS to prevent thermal runaway propagation at the battery pack level and protect human safety under extreme scenarios, even in the event of passive ignition.
Huawei Residential ESS LUNA2000-S1 successfully withstood a 20-minute external fire exposure challenge without explosion, effectively preventing the risk of secondary combustion or explosion. Meanwhile, under extreme challenges such as internal arcing and thermal runaway propagation, the system continues to achieve cell-level thermal runaway non-propagation, with no fire, explosion, or personal injury, comprehensively safeguarding household energy safety.
Winning the "Residential ESS Comprehensive Safety AQM Award," coupled with the world’s first highest‑level Safety Mark certification in the residential energy storage sector, forms dual authoritative recognition. It fully confirms that Huawei Smart String ESS boasts globally leading capabilities in safety technologies. Huawei is committed to setting higher safety standards to drive the high-quality development of the energy storage industry.
