Huawei Unveils LUTERRA™: A New Era in Energy Solutions

At the recent Intersolar Europe 2026 event, Huawei took bold steps forward in renewable energy technology with the introduction of its latest innovation, LUTERRA™. This new era of energy solutions, grounded in the FusionSolar strategy, is encapsulated in the theme "Making the Most of Every Ray." The unveiling of LUTERRA™ marks a significant milestone in the evolution of energy storage systems (ESS), particularly through its sophisticated "Smart String" technology.

Transition from LUNA to LUTERRA™

Huawei officially rebranded its ESS solutions from LUNA to LUTERRA™, reflecting its commitment to advanced energy management and integration capabilities. LUTERRA™ supports an impressive AC voltage rating of 1,000 V and boasts a solar panel capacity of 12.5 MW/50 MWh, setting new benchmarks within the industry.

During the event, Steven Zhou, President of the Smart PV ESS Product Line at Huawei Digital Power, discussed the future of photovoltaic systems and energy storage, highlighting a need for these systems to evolve into crucial assets that facilitate robust network operations. According to Zhou, the future of renewable energy solutions lies in their flexibility, intelligence, and capacity to adapt and respond to varying grid demands.

Five Technological Breakthroughs

Huawei’s LUTERRA™ platform is characterized by five notable technological advancements that promise to redefine energy management capabilities.

1. Smart String Architecture: Utilizing a pioneering smart string architecture at 1,000 V AC ensures enhanced battery consistency and improved energy conversion efficiency through the latest silicon carbide (SiC) modules.

2. Innovative Busbar Design: This architecture simplifies installation, increases capacity expansion capabilities, and facilitates cable connections, resulting in faster commissioning times and efficient land space utilization.

3. Smart Distributed Cooling System: With a 100% increase in thermal dissipation area and a reduction in fan speed by approximately 40%, this system significantly lowers operational noise levels.

4. Grid-Forming Technology: This cutting-edge technology enables synchronous network formation across millions of devices, ensuring adaptability to grid power fluctuations, thereby enhancing system resilience.

5. Digital Twin Platform: Leveraging cutting-edge digital and AI technologies, LUTERRA™ guarantees precise energy state forecasts (SOE) and power status (SOP). This digital backbone supports reliable energy exchange and maximizes profitability across the system's lifecycle.

Core Values Driving LUTERRA™

The LUTERRA™ platform is designed with four core values at its heart to drive energy transition:

• - Optimal Investment: LUTERRA™ focuses on quick delivery times and reduced costs that enhance returns on investment. For instance, for a 1 GWh energy storage installation, delivery times can be shortened by about 30%, while auxiliary equipment needs can be reduced by over 20%.

• - Higher Yields: The continuous improvement of round-trip efficiency, availability, and charge state measurement accuracy leads to increased energy throughput and higher overall returns over the product's lifecycle.

• - Utility-Scale Grid Formation: With its extensive capabilities in grid formation, including short circuit response and inertial response, LUTERRA™ paves the way for superior operational yields.

• - Safety Assurance (C2G): Empowered with Huawei’s C2G safety technology, the systems meet stringent safety standards, boasting a risk profile of less than 1 in a million as per regulatory safety maps.

Residential Solutions and Service Strategy

At the event, Huawei also launched LUTERRA™ S2, its new residential photovoltaic and energy storage system. Sun Power, President of the Residential System Division, emphasized the importance of this product in enhancing energy efficiency for over 4.3 million households globally. This system places a strong emphasis on user experience, intelligence, and security, ensuring top-tier energy performance in smart homes.

Finally, Allen Zeng, President of Technical Services at Huawei Digital Power, revealed a new service strategy aimed at optimizing installation value through exceptional performance and support across the lifecycle. With over 13 years of expertise in global service delivery, Huawei intends to utilize innovative platforms and services to enhance planning, construction, maintenance, and operational efficiency for its customers.

As LUTERRA™ ushers in this transformative era in energy solutions, Huawei sets itself at the forefront of the renewable energy landscape, committed to developing solutions that not only meet current demands but also pave the way for a sustainable future.
