Recently, Xiehang Energy Storage announced another milestone in its global expansion, as its 209kWh integrated photovoltaic-storage-charging cabinet has been successfully implemented in several overseas microgrid projects. Leveraging an all-in-one integrated design, stable grid-connected and off-grid switching capabilities, and a self-developed EMS (Energy Management System), the solution delivers autonomous distributed energy systems for power-deficient and weak-grid regions worldwide, further advancing global energy transition.
Against the backdrop of accelerating transformation in the global energy landscape, many remote areas, islands, mining sites, and communities abroad face challenges such as inadequate grid infrastructure, unstable power supply, and high expansion costs. Independent microgrids have thus emerged as the preferred solution for reliable local power supply and on-site utilization of solar-generated green electricity. The Xiehang 209kWh integrated photovoltaic-storage-charging cabinet-its mature flagship model-combines photovoltaic generation, energy storage, DC charging, and intelligent dispatching into a single unit, pre-assembled at the factory to significantly reduce on-site construction and commissioning time, perfectly suited to overseas projects with tight schedules and limited operational personnel.
The cabinet features A-grade lithium iron phosphate cells paired with a liquid-cooling thermal management system, ensuring excellent temperature balance and long-term battery cycle life and operational safety. Integrated within the cabinet are a PCS converter and high-power charging modules, enabling seamless switching between grid-connected and off-grid modes. In the event of a power outage, it can rapidly establish a localized microgrid to ensure continuous power supply to critical loads. Clean electricity generated by solar panels is first stored locally or used on-site, with surplus power directed toward charging loads, creating a closed-loop "generation-storage-charging-consumption" cycle. This effectively mitigates the intermittent fluctuations of solar power, improves green energy utilization, reduces customers' electricity costs, and decreases reliance on traditional fossil-fuel diesel generators.
The entire system is powered by Xiehang's proprietary EMS energy management system-the "brain" of the operation-which continuously collects data on solar output, battery state, charging load, and grid status, automatically optimizing energy dispatch strategies to achieve peak shaving, valley filling, load management, fault alerts, and remote monitoring. Overseas project owners no longer need complex supporting control systems to achieve automated microgrid operation, while cloud-based remote maintenance enables unified cross-regional management, greatly reducing long-term operational burdens. The product has passed multiple international safety and electrical certifications and complies with various national grid standards, meeting entry requirements for microgrid projects across Southeast Asia, Africa, Latin America, and beyond.
The recently deployed overseas microgrid applications span diverse scenarios, including power supply for remote communities, small-scale mining operations, and integrated energy stations on islands. To meet varying site-specific conditions-including solar irradiance, load profiles, and charging demands-Xiehang Energy Storage offers customized solutions, allowing flexible adjustments in PV capacity ratios and charging power, as well as modular expansion through multi-cabinet parallel connection, enabling evolution from small standalone microgrids to larger-scale integrated energy systems.
Backed by a continuously evolving portfolio of energy storage products, Xiehang has established a comprehensive export product ecosystem covering residential off-grid battery packs, portable photovoltaic storage kits, commercial and industrial energy storage cabinets, and the 209kWh/261kWh integrated photovoltaic-storage-charging cabinets. These solutions serve full-spectrum energy storage needs-from households and small outdoor applications to commercial-industrial and microgrid settings-and the company's customer network spans over a hundred countries and regions.
A spokesperson from Xiehang Energy Storage stated that the core challenge in many overseas regions lies in the lack of low-cost, highly reliable, and easily deployable integrated microgrid equipment. The large-scale deployment of the 209kWh integrated photovoltaic-storage-charging cabinet across multiple microgrid projects reflects market recognition of both product reliability and solution value. Moving forward, Xiehang Energy Storage will continue to focus on overseas microgrid market demands, continuously optimizing grid-forming control, high-temperature adaptability, and localized operation and maintenance capabilities. We will deliver standardized yet customizable photovoltaic-storage-charging microgrid solutions, further expanding into the global distributed renewable energy market, and leveraging energy storage technology to enable more regions to achieve stable power supply and low-carbon development.
