The global energy landscape is constantly changing. In remote islands, rural areas, and areas with weak power grids, households have long faced problems such as unstable power supply, frequent power outages, and difficulties in grid connection. For overseas households without power grids or with unreliable power grids, a stable and reliable household energy storage system is the core choice to achieve power independence and摆脱 reliance on diesel generators. Recently, Xiehang's energy storage products have been continuously exported to the global off-grid household market with 16 kWh lithium iron phosphate battery cabinets. With safe and stable hardware performance, friendly off-grid compatibility, and flexible installation design, they have entered the homes of hundreds of countries around the world, providing overseas users with an independent and sustainable home photovoltaic energy storage power supply solution.
The requirements for energy storage products in the off-grid household scenario are particularly demanding： they need to be able to adapt to fluctuations in sunlight, stably receive and handle solar power input, and ensure uninterrupted power supply throughout the day; they also need to consider home safety, easy installation, and be compatible with different regions' complex climate conditions such as high temperatures, high humidity, and sandstorms. The Xiehang 16 kWh off-grid energy storage cabinet uses LiFePO4 lithium iron phosphate cells as the core. Leveraging the inherent advantages of strong thermal stability and low risk of thermal runaway of lithium iron phosphate materials, it reduces the safety risks of household energy storage from the source and is highly suitable for long-term unmanned households with off-grid use. The cells are selected as A-grade products, undergo multiple rounds of rigorous aging, high-temperature, and shock tests, have a long cycle life, and are significantly superior to traditional lead-acid batteries, with lower long-term maintenance costs, meeting the needs of overseas households for long-term worry-free electricity consumption.
The product is equipped with Xiehang's self-developed intelligent BMS battery management system, which is the safety core of the entire energy storage cabinet. BMS monitors the voltage, current, and temperature of each string of cells in real time, integrates a complete set of protection strategies such as overcharge, overdischarge, overcurrent, short circuit, and high/low temperature warnings, can dynamically balance cell states, suppress single-string cell degradation, and ensure long-term consistency of the entire cabinet. The system supports CAN and RS485 communication protocols and is compatible with mainstream off-grid and hybrid inverters. During the day, the electricity generated by photovoltaics is stored in the energy storage cabinet, and at night, it is automatically released to power basic household appliances such as refrigerators, lighting, televisions, water pumps, and fans. Some high-power versions can also support large-power loads such as air conditioners. This meets the needs of overseas households for diverse daily electricity consumption. Users can remotely view SOC power, charging and discharging data, and equipment alarm information through the mobile app, allowing them to monitor the operation status of the energy storage system at home or remotely.
In terms of structural and environmental adaptability, the Xiehang 16 kWh off-grid energy storage cabinet adopts an integrated vertical cabinet design, with flexible installation methods, allowing for floor placement or wall mounting, occupying less space, and requiring no complex renovations. The entire machine has excellent dustproof and waterproof protection levels, optimized temperature control schemes for popular off-grid markets in Africa, Southeast Asia, and Latin America, reducing battery degradation speed in high-temperature environments, and operating stably in outdoor and semi-outdoor scenarios with large temperature differences and humid rain. The product has obtained multiple international safety certifications, meets market entry standards for different regions, and facilitates quick customs clearance and delivery for overseas distributors. It also supports parallel expansion of multiple cabinets, allowing for flexible addition of energy storage cabinets when household electricity demand increases, upgrading from small-capacity basic electricity use to larger-capacity independent household micro-grid.
Compared to industrial and commercial energy storage and large-scale photovoltaic storage and charging equipment, off-grid household energy storage requires a deeper understanding of local adaptation capabilities. Xiehang energy storage has conducted in-depth research on household electricity consumption habits in different regions： African rural households focus on lighting, mobile phone charging, and small appliances; Southeast Asian island users pay attention to battery endurance during rainy seasons with insufficient sunlight. Users of remote villas and farms in Europe and America need this as a long-term backup power source to cope with frequent power outages in the grid. Based on differentiated needs, Xiehang has provided dealers with standardized solution packages, offering inverter matching suggestions, installation guidance, and remote technical support to lower the installation threshold for local installers. At the same time, it has jointly built spare parts and after-sales networks with local agents to solve the problem of slow response in overseas household equipment maintenance.
As an important part of Xiehang's global energy storage product portfolio, this 16-degree household energy storage product complements PAYGO off-grid energy storage, portable photovoltaic kits, 209KWh/261KWh energy storage charging and power supply integrated cabinets, and prefabricated industrial and commercial cabins. It covers all scenarios of energy storage from basic household electricity usage, outdoor emergency power supply to microgrids and factory energy conservation. The product network covers hundreds of countries around the world. A responsible person from Xiehang's energy storage department stated that the core of off-grid household energy storage is not simply selling batteries, but enabling ordinary households to truly have autonomous and controllable electricity. Many households in remote areas overseas rely on photovoltaic systems combined with this 16kWh energy storage cabinet, no longer relying on unstable and price-volatile diesel, and enjoying cleaner and lower long-term costs in terms of electricity consumption.
Looking to the future, Xiehang's energy storage will continue to iterate this off-grid household energy storage cabinet, further optimizing low-temperature performance, upgrading BMS algorithms, expanding more capacity specifications, and simultaneously improving the accompanying photovoltaic + energy storage integrated solution. Leveraging the advantages of factory-scale production, it will continue to deliver high-quality off-grid household energy storage products, continuously deepen its focus on the global off-grid household energy storage sector, and bring safe, affordable green energy storage power to more overseas households, helping to promote the development of global distributed photovoltaic and household energy autonomy.
