[Munich, Germany, June 23, 2026] At Intersolar Europe 2026, Huawei held the 2026 Huawei FusionSolar Strategy & New Product Launch with the theme of "Making the Most of Every Ray." To help address the challenges of global energy transition and building new power systems, Huawei FusionSolar focuses on key fields such as grid forming, AI, and PV+energy storage system (ESS) integration, collaborating with global customers, partners, and industry organizations, exploring the future direction of the renewable energy industry.
2026 Huawei FusionSolar Strategy & New Product Launch
In new power systems dominated by renewables, the value of ESS will be reshaped, and the grid-forming ESS will be ubiquitous, supporting the stable operation of new power systems. Against this backdrop, Huawei announced the official upgrade of its ESS solution brand from LUNA to LUTERRA and launched the next-generation Smart String Grid-Forming ESS Platform LUTERRA, which features five technology breakthroughs, including the industry's first 1000 Vac smart string architecture, through-busbar architecture, and plant-level grid-forming technology. The platform supports 1000 V AC voltage and provides the industry's optimal array capacity of 12.5 MW/50 MWh. It offers customers optimal investment, higher returns, plant-level grid-forming capabilities, and cell-to-grid (C2G) safety, thus accelerating the construction of new power systems.

Leveraging Grid-Forming and AI Technologies to Build Scenario-Based Solutions
The penetration of wind and solar keeps rising steadily. Meanwhile, the power system is facing more serious challenges. For example, high dispatching complexity reduces the grid resilience, and the declining share of traditional synchronous generators also weakens system strength. To solve these issues, Europe is taking actions in four key directions: increasing grid investment, scaling up grid-forming ESS deployment, developing new grid codes including grid-forming requirements, and accelerating the shift of power market from simple energy arbitrage to diversified grid ancillary services.
Steven Zhou, President of Smart PV & ESS Product Line, Huawei Digital Power, delivered a keynote speech titled "Powering a Grid-forming & Intelligent Future, Driving Renewables Evolution." Zhou said, "Future PV and ESS products must evolve to grid-supporting assets. Future-proof flexibility, grid-forming capability, and intelligence will become essential. Huawei has always been striving in the research of power electronics and digital technologies. We continuously innovate and build industry-leading competence of grid-forming, AI and full-lifecycle safety & reliability. This core competence will empower our full-scenario Smart PV and ESS solutions, to bring maximum value for our customers while reinforcing grid stability in high renewable penetration. Ultimately, to accelerate renewables as the primary power source."

LUTERRA Sets New Industry Benchmarks with Five Technology Breakthroughs
Steve Zheng, President of Smart ESS Business, Huawei Digital Power, delivered a keynote speech titled "E-volving for Higher Returns" and officially launched the next-generation Smart String grid-forming ESS Platform LUTERRA. Zheng said, "Grid forming is unlocking the potential of energy storage. With over a decade of experience in energy storage technologies and mature practices in global PV+ESS plants, Huawei's next-generation Smart String Grid-Forming ESS Platform LUTERRA represents a leap in delivering maximum energy density from a single cabinet to arrays. It features four core values: optimal investment, higher returns, plant-level grid forming, and C2G safety, making it an excellent choice for customers looking to build ESSs for new power systems."

LUTERRA sets new industry benchmarks with five technology breakthroughs in power electronics and innovative architecture.
● The pioneering 1000 Vac smart string architecture improves battery consistency. The latest Huawei 1000 Vac SiC modules significantly improve conversion efficiency.
● The pioneering through-busbar architecture simplifies installation, capacity expansion, and cable connection, accelerating delivery and saving land resources.
● The pioneering smart distributed cooling increases the heat dissipation area by 100%, reducing the fan speed, and decreasing noise by about 40%.
● The leading plant-level grid-forming capability enables synchronous grid forming for tens of millions of devices and self-adaptation to changes in grid strength.
● Based on a unique digital twin platform and cutting-edge digital (bit) and AI technologies, the solution provides more accurate state-of-energy (SOE) and state-of-power (SOP) predictions, offering reliable digital support for power trading and significantly increasing the full-lifecycle returns.
LUTERRA is designed to empower a new future of energy transition with four core values:
● Optimal investment: High returns are achieved through fast delivery and lower costs. For example, for a 1 GWh ESS plant, the delivery time can be reduced by about 30% from construction to commissioning. The balance of plant (BOP), including land rent, cables, construction costs, and labor costs, can be reduced by more than 20%.
● Higher returns: By continuously improving the round-trip efficiency (RTE), availability, consistency, and state of charge (SOC) accuracy, the ESS can achieve higher energy throughput over the full lifecycle, thereby generating higher returns. Take a 12.5 MW/50 MWh ESS plant as an example. Assume a 20-year lifecycle, an electricity price spread of 11¢/kWh, and 1 cycle per day. Compared with conventional solutions, Huawei LUTERRA can increase energy throughput over its lifetime by more than 10%, yielding an additional return of 5.48¢/Wh.
● Plant-level grid forming: The six plant-level grid-forming capabilities, including short circuit level, wideband oscillation damping, inertia response, primary frequency regulation, black start, and on/off-grid switching, unlock potential for higher returns.
● C2G safety: Huawei FusionSolar has launched the industry's first Full-Lifecycle Quantitative Safety Assessment Framework and safety risk map (R-Map) for battery energy storage systems (BESS). Within this framework, safety risks are classified into three zones—A, B, and C—based on hazard severity and probability of occurrence. Zone A represents unacceptable risk, Zone B denotes risk requiring mitigation, and Zone C indicates generally controllable risk. Huawei's C2G safety technology has enabled grid-forming ESS to meet the Zone C safety standard, meaning the risk is less than 1 in 1 million on the R-Map.
