Huawei Digital Power's Groundbreaking Solutions for Energy Transition

At the recent Intersolar Europe 2025 event, Huawei Digital Power made headlines with the introduction of its innovative FusionSolar strategy under the theme "Smart PV ESS Powering a Grid Forming Future." This launch showcased a commitment to developing robust energy strategies and products that aim to accelerate the global transition to renewable energy while constructing modern electric frameworks. With approximately 300 esteemed customers and international partners present, the event highlighted a crucial leap in the renewable energy sector.

The launch emphasized the integration of advanced technologies, focusing on the concept of grid formation across all scenarios—utility-scale, microgrids, industrial, commercial, and residential applications. This forward-thinking approach is designed to promote stability and reliability in new electrical systems that heavily rely on renewable energy sources.

Key Features of Huawei's FusionSolar Strategy

Steven Zhou, president of Huawei's Smart PV ESS Product Line, outlined strategic objectives to integrate the "4T" technologies—bit, watt, heat, and battery. This vision aims at crafting a solid energy infrastructure for newly formed electrical systems. The strategy includes three primary value propositions:

1. Grid Formation Across All Scenarios: By implementing comprehensive grid-forming technology, the strategy ensures the reliable production, transmission, distribution, and consumption of electricity, thus securing long-term stability for the emerging electrical systems.

2. Cell-to-Grid Security: Each phase incorporates robust security measures to ensure the safety of equipment, personnel, and assets, reflecting a commitment to high standards of operational security.

3. One Model for All: The approach promotes flexible scalability, compatible with various business models. The collaboratively managed PV+ESS platform, empowered by AI, enables energy yield predictions and automatic operational policy optimizations.

The Smart String Grid Forming ESS

In addition to these strategic objectives, Huawei's newly introduced Smart String Grid Forming ESS addresses the integration challenges faced by renewable energy sources. This groundbreaking platform promises stability across varying states of Battery Energy Storage Systems (BESS) and maintains performance across different network conditions (SCR), enhancing future electrical networks' adaptability. The solution has been successfully implemented in significant projects, including a massive 1.3 GWh ESS project and a 400 MW photovoltaic installation in the Red Sea area, recognized as the world’s largest PV + ESS microgrid. This microgrid operates entirely on renewable energy and has consistently delivered over 1 billion kWh of green electricity for more than 18 months.

Moreover, a similar Smart PV+ESS installation in Ngari Prefecture, China, showcases its effectiveness in extreme conditions. Located over 4,600 m high, this site experiences severe weather and unstable grid conditions, yet has achieved a remarkable solar power increase of 75% from 1.5 MW to 12 MW. This system demonstrates the ESS's capacity to support the grid multiple times over short periods, indicating the technological leadership Huawei holds.

Redefining Safety and Energy Management

Huawei's commitment to safety is illustrated in its six-cell-to-grid safety designs, which enhance security measures from standard levels to superior pack-level protection. The integration of sophisticated diagnostic and intelligent battery management systems significantly boosts proactive safety capabilities.

Furthermore, the new Home Energy Management Solution 6.0 enhances energy management for residential settings. This solution encompasses innovative products like the LUNA S1-7kWh home ESS, boasting a 15-year warranty, an energy usable capacity exceeding industry averages by 40%, and flexible scalability up to 252 kWh. Across the globe, Huawei's residential PV+ESS solution has gained popularity, earning the trust of 3.9 million households and 30,000 installers, facilitating greater energy independence.

Conclusion: A Vision for the Future

Huawei FusionSolar strives for a transformative impact on energy standards worldwide, creating smart PV + ESS solutions that not only meet but exceed customer expectations. As these initiatives take root, they pave the way for a sustainable future powered by renewable energy, ensuring a cleaner and more stable energy landscape for generations.

In essence, Huawei Digital Power is not just responding to the global energy challenge but is setting the pace for a new era in the energy sector. By embracing innovation and prioritizing comprehensive solutions, Huawei aims to fundamentally reshape the dynamics of energy production and management on a global scale.
