Huawei Digital Power has hosted a FusionSolar strategy and new product launch at the 2025 edition of Intersolar Europe 2025. Under the theme of “Smart PV and ESS: Powering a Grid Forming Future,” the company welcomed some 300 global customers and partners, the launch highlighting all-scenario grid forming and high-quality development and introducing next-generation grid forming ESS products and solutions for utility, microgrid, C&I and residential applications.
Steven Zhou, President of the Smart PV and ESS Product Line, announced the strategic goal of integrating “4T” technologies (bit, watt, heat and battery) to build the energy infrastructure for new power systems. He also unveiled three key value propositions: all-scenario grid forming, cell-to-grid safety and “one matches all,” accelerating the development of new power systems powered entirely by renewable energy.
Steve Zheng, President of Smart ESS Business, went on to release the next-generation all-scenario smart string grid forming ESS platform, which includes the new utility and C&I smart string grid forming ESS. Designed to address challenges in renewables grid integration and ESS safety, the Huawei platform offers all-scenario grid forming, cell-to-grid safety, full-lifecycle cost-effectiveness and full-link digitalization. The platform defines the gold standard of grid-forming capabilities, whereby the grid forming ESS can adapt at any time to any BESS SOC status and grid SCR, while supporting system evolution to enhance future power grids.
The solution has already been applied to the Red Sea 1.3 GWh ESS and 400 MW PV project in the Middle East. This project is the world’s largest PV+ESS microgrid, powering the city with 100% renewable energy. The microgrid has been running stably for more than 18 months, during which time it has provided more than 1 billion kWh of green electricity. The 30 MW PV and 6 MW/24 MWh ESS project in China’s Ngari prefecture also uses Huawei’s Smart PV+ESS solution. The fully grid-forming power plant is located at a high altitude (about 4,600 m), with extremely low temperatures and weak grid conditions. Its PV power output can be increased from 1.5 MW to 12 MW, increasing PV integration by 75%. According to plant statistics, the ESS provides grid support more than 30 times within a 10 day period, achieving more value from energy storage through power electronics technology, as well as ensuring grid safety and stability through digital intelligence, opening a new chapter of grid forming renewable energy worldwide.
Huawei Digital Power also redefines ESS safety with six cell-to-grid safety designs to upgrade protection from the conventional container-level to the more refined pack-level, ensuring enhanced protection for the ESS. Combined with multi-dimensional, full-link and intelligent diagnosis of the battery management system (BMS), the system’s proactive safety capability is greatly improved.
Sun Power, President of Residential PV & ESS Business, released the new home energy management solution 6.0, covering green power generation and intelligent energy consumption and leading the way in home energy management. The solution includes a full range of new products, including the residential ESS LUNA S1-7kWh. The ESS has an industry-leading 15-year warranty, over 40% more usable energy than the industry average and on-demand capacity expansion up to 252 kWh. It can also adapt to a wide range of residential and small-sized C&I scenarios. Huawei’s residential PV+ESS solution, thanks to its strong technical capabilities, has become the preferred choice for 3.9 million households and 30,000 installers worldwide. From a zero-carbon house in Italy to a PV town in Sweden, the solution is optimal for home energy independence and community energy sharing.
