AboutThe Yuanhe Energy team has been deeply engaged in the fields of energy storage systems, power electronics, and automatic control for many years, boasting over a decade of experience in the energy storage industry. By collaborating with industry partners, they have developed safer, smarter, and more efficient energy storage integration products. The company’s energy storage system integration products and solutions can meet the needs of various application scenarios, including combined frequency modulation for thermal power plants, energy storage supporting new energy generation, user‑side energy storage, and independent shared energy storage power stations. -
SolutionsEnergy storage is a flexible solution for mitigating grid fluctuations caused by renewable energy generation. When deployed at an appropriate scale, energy storage can effectively reduce curtailment rates of wind and solar power, enhancing the grid’s ability to absorb these sources; it can also participate in ancillary services such as peak shaving and frequency regulation, thereby generating additional revenue. -
ProductsThe company’s core business encompasses the R&D, production, and sales of large-scale energy storage system integration products, commercial and industrial energy storage products, and digital energy products, as well as the development, construction, operation, and value‑added services for energy storage power plants. -
ContactLet us join hands to overcome the technological bottlenecks in off‑grid flexible DC power supply, optimize energy storage efficiency, reduce operation and maintenance costs, and deliver clean electricity to every remote corner, jointly creating a bright future of energy inclusivity, green sustainability, and low carbon emissions.
