As global electrification and low-carbon transformation accelerate, overseas industrial parks and commercial charging stations commonly face challenges such as high grid expansion costs, significant peak load impacts, difficulties in integrating photovoltaic (PV) power, and insufficient power supply stability. Under traditional models, PV systems, energy storage, and charging equipment are procured separately and installed in stages, resulting in complex integration and commissioning processes, extended project timelines, and long-term risks related to equipment compatibility and operations management. Recently, Xiehang Energy Storage has accelerated the international deployment of its one-stop integrated green power solution, with its flagship 209kWh PV-storage-charging cabinet successfully deployed across multiple overseas industrial parks and commercial charging stations. Leveraging highly integrated design and a self-developed EMS (Energy Management System), Xiehang delivers a complete closed-loop energy service covering solar generation, energy storage for peak shaving, and electric vehicle (EV) charging.
The Xiehang 209kWh integrated cabinet features a prefabricated, all-in-one design that consolidates lithium iron phosphate (LFP) battery cells, PCS inverters, DC charging modules, electrical distribution and fire protection systems, and liquid-cooled thermal control into a single unit. Full system integration and performance verification are completed at the factory before shipment. Upon arrival at the site, only PV connection, grid integration, and structural mounting are required for immediate operation-significantly reducing on-site cabling and equipment integration efforts. This greatly lowers construction, civil engineering, and commissioning costs, making it ideal for space-constrained environments such as overseas construction sites, logistics parks, commercial charging stations, and island facilities where installation conditions are limited.
The battery cells use Grade A LFP chemistry paired with a proprietary BMS (Battery Management System) that continuously monitors voltage, current, and temperature of each cell, enabling active balancing and incorporating multi-layer protections against overcharging, deep discharging, short circuits, and overheating. The integrated liquid cooling system ensures stable temperature control even in high-temperature regions like the Middle East and Southeast Asia, slowing battery degradation and extending cycle life. The entire system meets multiple international safety certifications, satisfying market entry requirements across different countries.
At the heart of this solution is Xiehang's self-developed EMS energy management system, which enables coordinated dispatch among PV generation, energy storage, charging loads, and the grid. During normal park operations, solar power is prioritized to meet daily production and office electricity needs and to charge EVs, with surplus energy stored in batteries. During evening peak charging hours or high-tariff periods, stored energy is discharged to support fast-charging loads, reducing peak demand on the grid and helping avoid costly demand charges-eliminating the need for expensive grid upgrades. In the event of grid outages or unstable voltages, the system quickly switches to off-grid microgrid mode, ensuring uninterrupted power supply to critical loads and charging stations, significantly improving reliability.
For commercial charging station operations, the EMS supports smooth power control, preventing grid disturbances caused by simultaneous high-power startup of multiple chargers and ensuring consistent user experience. The system includes various configurable operating strategies, allowing customers to flexibly switch between self-consumption, peak-valley arbitrage, and backup power modes based on local electricity pricing, solar irradiance, and operational goals.
Unlike conventional providers offering only energy storage hardware, Xiehang delivers a fully integrated turnkey solution. In addition to the 209kWh integrated cabinet, the package includes a cloud-based energy monitoring platform that allows operators to remotely access comprehensive data-including power generation, battery state-of-charge (SOC), charging power, and equipment alarms-and automatically generate energy reports. Remote parameter adjustment and fault diagnosis further reduce the complexity of cross-border operations. Xiehang also provides partners with full support services including solution design, inverter matching guidance, installation training, and spare parts availability, enabling local integrators to deploy projects efficiently. The system supports modular expansion through parallel connection of multiple units: small-scale charging stations can start with a single cabinet, while medium-to-large industrial parks can scale up by adding cabinets to form clustered microgrids, flexibly meeting diverse green energy demands.
The current model has been widely deployed in logistics parks, commercial fast-charging stations, and industrial microgrids, covering multiple overseas regions including Southeast Asia, the Middle East, and Latin America. HeXieHang's product portfolio-comprising the 261kWh integrated photovoltaic-storage-charging cabinet, commercial and industrial prefabricated energy storage containers, 16kWh residential energy storage systems, PAYGO off-grid storage solutions, and portable PV storage kits-forms a comprehensive solution matrix that meets diverse energy needs, from centralized industrial power consumption to household off-grid electricity and accessible energy for remote areas. According to overseas project managers, many international park and charging station operators are no longer focused solely on hardware pricing but increasingly value system stability, cost reduction through lower electricity bills, and ease of long-term maintenance. This is precisely why the 209kWh integrated photovoltaic-storage-charging cabinet has gained strong customer recognition.
As the overseas distributed green energy market continues to expand, demand for zero-carbon upgrades in industrial parks and charging stations remains robust. Moving forward, HeXieHang Energy Storage will further optimize the EMS scheduling algorithm of its 209kWh integrated unit to enhance adaptability in weak grid environments and improve self-consumption rates of solar power. The company will also strengthen localized technical support networks and continue delivering standardized, rapidly deployable turnkey photovoltaic-storage-charging green energy solutions. These efforts aim to help more overseas parks and charging stations achieve cost reduction, operational efficiency, and low-carbon operations, continuously driving global transformation toward distributed clean energy.
