Huawei Digital Power Showcases All-Scenario Grid-Forming Innovations at Intersolar Europe 2025, Advancing Global Energy Transition

Huawei Digital Power is showcasing its all-scenario grid-forming Smart PV+ESS products and solutions at Intersolar Europe 2025, held in Munich. These advanced technologies, along with their proven business applications, are accelerating the development of new power systems and promoting high-quality growth across the global renewable energy industry.

Carbon neutrality and the global shift toward cleaner energy have become shared priorities worldwide. Achieving these goals requires the development of new power systems capable of supporting increased renewable energy integration and wider use of power electronics across generation, transmission, distribution, and consumption. These modern systems merge energy flows with information flows, embodying the concept of “bit manages watt.” This integration allows for flexible dispatch, enhanced safety, greater reliability, and stable grid-forming control—making such systems a critical foundation for the energy transition.

In utility-scale applications, Huawei’s Smart String Grid Forming ESS delivers comprehensive grid-forming capabilities, ensuring performance across all scenarios and grid conditions throughout the entire energy lifecycle—from generation to transmission, distribution, and consumption. Designed with cell-to-grid safety, full-link digitalization, and lifecycle-optimized investment in mind, the solution guarantees stable grid forming across all states of charge (SOC) and short circuit ratios (SCR), at any time. Future-ready by design, it also supports ongoing technological advancements to meet the evolving needs of power systems.

• On the generation side, the solution can be adapted to any grid and power can be stably transmitted. The voltage, frequency, and power angle control functions and application effects are equivalent to those of synchronous condensers. The grid-forming ESS solution features simple maintenance and lower lifecycle investment.
• On the transmission and distribution side, the solution stabilizes voltage and frequency, supports black start, and mitigates weak power supply in load centers. As the electric power market is expanding from energy and capacity markets to ancillary service markets such as reactive power and inertia services, Huawei’s Smart String Grid-Forming ESS continues evolving to meet customers’ demands. It offers one platform that is adaptable to diverse business models and supports flexible evolution.
• On the consumption side, seamless on/off-grid switching and stable off-grid operation enable microgrids that are 100% powered by renewables.

Hierarchical control is vital for a microgrid system to achieve the optimal balance between economy and stability. Huawei’s microgrid control system carefully considers time-based control and function implementation and is divided into three layers: stable grid-forming control, efficient coordinated control, and intelligent optimized dispatching. It provides strong technical support for the low-carbon and efficient energy transition of industries such as mining.

Designed to enable sustainable operations in the commercial and industrial (C&I) scenario, Huawei’s 215 kWh Smart Hybrid Cooling ESS features proactive safety, premium quality, and higher profitability.

• Proactive safety: Huawei proposes the concept of “Cell-to-Consumption (C2C) Dual-link Safety Architecture,” which refers to electrical and thermal link safety across cell, pack, system, and consumption. The ESS is certified by UL 9540A, VDE-AR-E 2510, and CE standards, and is the world’s first product to obtain the L3 highest safety certification (Prime safety) by TÜV Rheinland.
• Premium quality: The ESS runs stably in extreme conditions, with no power derating at 50°C* or at an altitude of 4000 m*.
• Higher profitability: The unique pack-level optimization has been upgraded to version 2.0, achieving 91.3%* round-trip efficiency (RTE) and 100% depth of discharge (DOD) for more usable energy throughout the lifecycle.

Huawei’s newly launched Home Energy Management Solution 6.0 sets a new benchmark in green home energy by integrating green power generation with intelligent energy usage. The solution features a complete lineup of next-generation products, including the residential energy storage system LUNA S1-7kWh. This ESS offers an industry-leading long-term warranty, over 40% more usable energy than the market average, and flexible capacity expansion up to 252 kWh. It is also adaptable for a wide range of residential and small commercial and industrial (C&I) applications. At Huawei’s residential exhibition area, visitors can witness the product’s durability and performance under extreme conditions, including 40 cm water immersion, 5-ton weight pressure, resistance to wind and sand, and extreme cold.

The energy transition is more than just a matter of technological advancement—it is a global commitment to sustainable development. Huawei Digital Power remains dedicated to continuous innovation, integrating its “4T” technologies—bit, watt, heat, and battery—and collaborating with global customers and partners to accelerate the development of new power systems through comprehensive grid-forming solutions across all scenarios.
