PALMA, SPAIN – <a href="https://www.media-outreach.com/">Media OutReach Newswire</a> – 11 November 2026 - Huawei announced the launch of HUAWEI LUTERRA S2, an all-in-one residential energy system that integrates a hybrid inverter, storage, and AI-powered energy management in one stackable unit. Designed for easy deployment, LUTERRA S2 can be installed and commissioned in minutes. Available in single-phase (3-10 kW) and three-phase (5- 20 kW) configurations, LUTERRA S2 is the industry's first all-in-one residential energy system built on Huawei's proprietary full-SiC (silicon carbide) architecture, delivering exceptional efficiency, power density, and reliability. <figure data-image-width="0" data-image-height="0" style="display: block;width: 100%;margin: 0px;padding: 0px;text-align: center" align="center"> <img src="https://images.media-outreach.com/release.php/Thumb/1600x1067/836831/836831-S2-jpg-1600x1067.jpeg" alt="HUAWEI LUTERRA S2" width="1600" style="width: 100%;margin: 0px"> <figcaption class="" style="text-align: left;font-size: 16px;line-height: 24px;display: block;margin: 0px;width: 100%"> <div align="left" style="margin-top: 16px;text-align: start"> HUAWEI LUTERRA S2 </div> </figcaption> </figure> "We are thrilled to introduce HUAWEI LUTERRA S2, our next-generation all-in-one residential energy system," said Steve Zhang, President of Huawei Distributed PV &amp; BESS Business. "By combining full-SiC architecture, AI-driven energy management, and industry-leading safety, LUTERRA S2 is designed to be smaller, lighter, quieter, safer, smarter and more powerful than ever before." <figure data-image-width="0" data-image-height="0" style="display: block;width: 100%;margin: 0px;padding: 0px;text-align: center" align="center"> <img src="https://images.media-outreach.com/release.php/Thumb/1600x1067/836838/836838-Launch-jpg-1600x1067.jpeg" alt="Steve Zhang delivering the speech" width="1600" style="width: 100%;margin: 0px"> <figcaption class="" style="text-align: left;font-size: 16px;line-height: 24px;display: block;margin: 0px;width: 100%"> <div align="left" style="margin-top: 16px;text-align: start"> Steve Zhang delivering the speech </div> </figcaption> </figure> As solar, storage, EV charging, and home energy management continue to converge, homeowners are looking for solutions that go beyond power and capacity to deliver greater intelligence, efficiency, and safety. To meet these evolving needs, Huawei introduces HUAWEI LUTERRA S2, a breakthrough residential energy system built on three defining pillars: Ultimate Experience, Ultimate Intelligence, and Ultimate Safety. Ultimate Experience: From Core Technology to Everyday Experience LUTERRA S2 combines high power density and compact design, delivering 20 kW-class power in a streamlined form factor. Powered by Huawei's proprietary full-SiC architecture and ANPC topology, it achieves up to 99% efficiency. Built-in energy optimizers enable up to 5.0 MWh/kWh of lifetime usable energy and a design lifespan of more than 15 years. Beyond technical performance, LUTERRA S2 is designed to integrate naturally into modern homes. Its art-inspired design, Red Dot Award-winning hardware, App 3.0, and intelligent breathing light create a seamless blend of technology and lifestyle. The industry's first 20 kW-class all-natural cooling design eliminates the need for external fans and maintains operating noise below 29 dB. Ultimate Intelligence: From Automation to Active Decision-Making Through the AI Energy Management 2.0 platform, LUTERRA S2 brings intelligence to energy planning, operation, and value optimization. By integrating weather forecasts, electricity prices, household loads, and energy status, the platform intelligently coordinates photovoltaic systems, energy storage, EV charging, heat pumps, and virtual power plants (VPPs). This coordination maximizes the value of every kilowatt-hour generated, stored, and consumed. For homeowners, the AI Assistant turns complex energy management into simple, conversational interactions, enabling users to make informed energy decisions with ease. For installers, AI 3D modeling simplifies planning and design by identifying roof structures and installation environments. AI-powered diagnostics and remote support further enhance operation and maintenance efficiency. Ultimate Safety: From Cell-Level Protection to End-to-End Safety Safety is built into every layer of LUTERRA S2, from battery cells to system-level operations. Each battery cell incorporates an independent protective isolation structure, supported by Huawei-developed safety components and localized non-propagation design to help contain thermal risks. An intelligent smoke-duct design enables directional pressure relief, smoke evacuation, and cooling, while continuous AC and DC terminal temperature detecting provides proactive detection and protection of critical connections. LUTERRA S2 has been validated against relevant EU Battery Regulation requirements and complies with key international standards, including IEC 63027 AFCI. It has also undergone TÜV Rheinland safety testing, including a cell thermal runaway test, a 20-minute fire test at 1,000°C, and a 20% hydrogen explosion test, as well as UL 9540A validation.LUTERRA S2 has received the highest-level Safety Mark certification from TÜV Rheinland, backed by the industry's first cell-level thermal insulation design, safety venting design, and full-link terminal over-temperature protection. Leading the Future of Residential Energy Systems More than an energy storage system, LUTERRA S2 connects intelligent technology, enhanced quality of life, and sustainable living. Huawei is setting a new benchmark for next-generation residential energy and accelerating the transition toward a smarter, more sustainable future.
