Recently, Zhejiang Xiehang Energy Storage announced strong overseas market success. Its 261kWh solar-storage-charging integrated energy storage cabinet, powered by a self-developed EMS (Energy Management System), has secured bulk orders from multiple countries across Europe, Southeast Asia, and Africa. Thanks to its stable and reliable system performance and flexible adaptability to diverse application scenarios, the product continues to be delivered internationally-marking Xiehang's successful large-scale deployment in overseas commercial and industrial solar-storage-charging markets and earning global recognition for China's integrated energy storage solutions.
Against the backdrop of accelerating global energy transition, demand for distributed photovoltaics, energy storage, and integrated charging microgrids is surging. Industrial parks, shopping malls, logistics hubs, and off-grid communities abroad commonly face challenges such as insufficient grid capacity, volatile electricity prices, difficulties in integrating solar power, and inadequate emergency power supply. Traditional solar-storage-charging systems often rely on third-party generic energy management systems, which suffer from rigid dispatch strategies, poor multi-device coordination, and reduced stability under high temperatures or voltage fluctuations-making them ill-suited to varying national grid standards and complex climatic conditions. Addressing these real-world pain points, Xiehang Energy Storage has positioned its self-developed EMS as a core competitive advantage, launching the standardized 261kWh integrated cabinet that enables intelligent, end-to-end control across photovoltaic generation, energy storage, and new-energy charging.
The self-developed EMS serves as the "intelligent brain" of the entire integrated cabinet. Equipped with AI-based smart dispatch algorithms, it collects real-time data on PV output, battery state-of-charge (SOC), charger load, grid voltage, and time-of-use pricing, enabling millisecond-level energy allocation decisions. The system automatically switches between various operating modes-including PV-first self-consumption, peak-valley arbitrage, demand-side management, and off-grid emergency backup. When sunlight is abundant, the system prioritizes using green PV power to charge electric vehicles, storing excess energy in batteries. During low solar generation or peak grid periods, stored energy is discharged to meet demand, maximizing PV self-consumption and reducing customer electricity costs. In the event of a grid failure, the system rapidly triggers seamless islanding operation, ensuring uninterrupted power supply to critical loads and meeting emergency power needs in remote areas and microgrid projects. Additionally, the EMS features built-in multi-dimensional fault prediction, remote maintenance, and data analytics capabilities, enabling full lifecycle equipment monitoring, significantly reducing on-site operational complexity, and supporting unattended operations required by overseas customers.
The 261kWh integrated cabinet adopted for international deployment features a fully integrated design, consolidating battery cells, BMS (Battery Management System), PCS (Power Conversion System), EMS, liquid cooling, fire protection, and distribution units into a standard outdoor cabinet. This compact, easy-to-install solution supports modular expansion through parallel connection of multiple cabinets, making it highly adaptable to small-scale commercial and industrial sites, public charging stations, and solar carports. The cabinet incorporates a comprehensive multi-layer safety architecture combined with precise liquid cooling technology, effectively controlling battery temperature differentials and ensuring stable operation even under extreme overseas climate conditions-such as high humidity, wide diurnal temperature swings, and high ambient temperatures-significantly extending system lifespan. From cell selection and system integration to final testing, the product strictly complies with international safety and grid standards, having obtained multiple international certifications and meeting grid interconnection requirements across Europe, Southeast Asia, and Africa, thereby addressing stringent demands for system reliability and safety in overseas projects.
"Overseas customers are no longer focused solely on storage capacity and price; they now place greater emphasis on the overall system's coordinated stability, local adaptability, and long-term operational support." The foreign trade manager at Xiehang Energy Storage explained that their self-developed EMS enables the product to break free from limitations imposed by generic control systems, supporting customized dispatch strategies tailored to power regulations in different countries. This is precisely why the 261kWh integrated photovoltaic-storage-charging cabinet has secured orders across multiple international markets. Once deployed, the project helps overseas customers achieve peak shaving and valley filling, reduce electricity costs, enhance local solar power utilization, and build a green energy replenishment network, thereby supporting regional carbon neutrality goals.
In recent years, Xiehang Energy Storage has continuously focused on R&D of energy storage systems and pack manufacturing services, adhering to an independent technological development path. The company has consistently refined core software algorithms such as EMS and BMS, expanding its product portfolio to include integrated photovoltaic-storage-charging cabinets, portable energy storage units, and commercial-industrial storage-charging cabinets. Its market presence spans Europe, the Middle East, Southeast Asia, Africa, and other global regions. The successful acquisition of these multi-country orders not only reflects market recognition of Xiehang's product reliability and technical capabilities but also marks a significant step forward in the company's globalization strategy.
Looking ahead to the global new energy market, Xiehang Energy Storage will continue to iterate its proprietary EMS algorithms and integrated energy storage products, further enhancing system reliability under complex operating conditions. The company will also strengthen its overseas delivery and localized technical support services, consistently delivering high-performance, cost-effective, and reliable integrated photovoltaic-storage-charging energy solutions. These efforts aim to accelerate the global transition to clean energy and further expand the influence of Chinese energy storage brands in international markets.
