Recently, Xiehang Energy Storage successfully deployed its one-stop commercial and industrial energy storage solution across multiple overseas factory projects. The solution leverages standardized prefabricated energy storage units as the hardware platform, integrated with a self-developed Battery Management System (BMS) and an Energy Management System (EMS), enabling overseas manufacturing enterprises to achieve peak shaving, load leveling, demand-side management, solar power integration, and backup power supply. This helps stabilize production loads and reduce electricity costs, providing a highly reliable and rapidly deployable pathway for green transformation at overseas facilities.
In overseas manufacturing environments, common challenges include significant fluctuations in power demand, high peak-to-valley electricity price differentials, unstable grid supply, and lengthy approval cycles for grid expansion. Many overseas factories have installed on-site photovoltaic (PV) systems, but PV generation is intermittent, leading to curtailment issues and difficulty matching continuous production demands. Xiehang's prefabricated unit solution adopts a factory-integrated model, incorporating lithium iron phosphate battery modules, PCS inverters, liquid cooling thermal management, fire suppression systems, and electrical protection units within each container. Full-system commissioning tests are completed before shipment, allowing for quick installation, wiring, and grid connection upon arrival-significantly shortening on-site construction time and adapting well to limited site conditions and tight schedules typical of overseas construction sites.
At the heart of the system, Xiehang's proprietary BMS plays a critical role in ensuring battery safety and longevity. It enables millisecond-level real-time monitoring of voltage, temperature, and internal resistance for every battery string, featuring active balancing, overcharge/overdischarge protection, thermal runaway early warning, and fault isolation. By precisely managing battery operating parameters, it maintains cell consistency across the entire container, slows battery degradation, and extends the overall lifecycle of the energy storage system. Integrated with the EMS, the BMS coordinates dispatch between PV arrays, the grid, and factory loads, automatically executing charging and discharging strategies: storing energy during off-peak hours and discharging during peak periods to minimize maximum demand and reduce high demand charges. In the event of grid outages, the system swiftly switches to island mode, ensuring uninterrupted operation of critical equipment such as air compressors, assembly lines, and central control systems, thereby avoiding production losses due to unexpected power interruptions.
The end-to-end solution supports flexible scalability, allowing factories to add prefabricated units in phases according to capacity planning without requiring large upfront investments. Additionally, the system enables remote cloud-based operations, allowing overseas customers and Xiehang's technical team to monitor container performance, battery health, and financial returns online, remotely update control strategies, and troubleshoot alerts-greatly simplifying cross-border maintenance. Designed to meet international certification standards, the product is compatible with regional grid regulations and extreme outdoor conditions-including high temperatures and humidity-across Southeast Asia, the Middle East, Africa, and Latin America, with robust protection, thermal control, and fire safety features tailored to demanding outdoor environments.
Backed by a continuously expanding product portfolio, Xiehang Energy Storage has established a comprehensive range of energy storage solutions-from residential off-grid battery packs and portable storage units to integrated photovoltaic-storage-charging cabinets and large-scale commercial and industrial prefabricated containers-serving diverse applications including home microgrids, small to medium commercial and industrial sites, large factories, and campus microgrids. Previously, products such as PAYGO off-grid storage systems, 209kWh integrated PV-storage-charging cabinets, and 314Ah battery module commercial storage cabinets have been deployed in hundreds of countries worldwide, building extensive experience in localized delivery and project support in overseas markets.
A Xiehang Energy Storage official stated that overseas factory customers seek not just a single energy storage device, but a complete energy solution that ensures stable, cost-effective operations and reduces electricity-related risks. Xiehang will continue to iterate its BMS and EMS algorithms, optimize the safety design and thermal control performance of prefabricated containers, and further refine its one-stop delivery capabilities. The company aims to promote integrated photovoltaic-storage solutions to more overseas industrial parks and manufacturing facilities, helping international enterprises enhance their energy self-reliance and controllability, and empowering global industrial sectors with energy-saving and decarbonization through energy storage technology.
