What is residential sodium ion battery？
- For home energy storage, There are following problems of Li-ion battery in Year 2026:
- Li-ion batteries are unsafe, posing risks and hazards of overheating, explosion, and fire.
- Li-ion battery power will decrease in cold winters.
- Li-ion battery power is limited in hot summers.
- Li-ion battery power supply is unstable in high-altitude areas.
- Li-ion batteries cannot withstand wind, rain, snow and dust corrosion.
- To meet the needs for “safe home battery, power anytime,” we have integrated NFPP prismatic sodium ion cell and smart BMS, based on extremely safe sodium ion battery technology and advanced BMS technology, to offer an advanced and safe Residential Sodium Ion Battery.
- In 2026, we have 3 models of residential sodium ion batteries:
- 48V160AH sodium ion battery (Rack Mount)
- 48V160AH sodium ion battery (Wall Mount)
- 48V320AH sodium ion battery (Floor Standing)
- These 3 models of 48V residential sodium ion battery are primarily designed for residential and light commercial users, providing a safe, reliable, stable, and environmentally friendly power supply to meet the needs for safe and readily available electricity.
- The biggest advantage of the Residential Sodium Ion Battery is that, instead of “unsafe Li-ion batteries,” Residential Sodium Ion Battery is very safe and robust, not only it can offer reliable power when it is installed in outdoor, but also it can discharge stable power even in extreme conditions
Why chose residential sodium ion battery?
- Safest NFPP SIB technology, never fire nor explosion
Based on sodium Ion battery technology,residential Sodium ion battery are made of 160AH NFPP Sodium Ion Prismatic Cell, this mass-produced and needle-punched smokeless cells have fully passed rigorous safety testing,no risk of fire or explosion
- All-weather operation, adaptable to extreme climates.
48V residential sodium-ion battery can discharge from -40℃ to 60℃，it ensures stable operation even in harsh winters or scorching summers, It provides safe, reliable, stable, and environmentally friendly power for home and light commercial users under varying operating temperatures.
- Full levels safety from cell, module, pack and system
48V residential sodium ion battery is built-in multi-layer battery management system protection functions, that can ensure safe operation under any operating conditions. There are aerosol fire extinguisher with module, to ensure rapid and effective response in emergencies. Meanwhile,IP65 protection not only provides dust and water resistance but also withstands harsh weather conditions such as sandstorms, eliminating any risk.
- Various installation methods, easy to install.
48V residential sodium ion battery supports rack mount installation, wall mount installation and floor standing installation, you can install in door or outdoor. Because of IP65 dust-proof and waterproof protection, it is easy to resist rain and sandstorms, most importantly, its compact designs can help you saves space, convenient and safe installation.
- Flexible expansion to meet ever-growing needs.
48V160AH residential sodium ion battery supports up to 20 blocks in parallel, which means total system is 20*7.68KWH=153.6KWH.While 48V320AH residential sodium ion battery also supports 20 blocks in parallel, therefore total 307.2KWH can be expanded to meet scalability.
- Multi-Scenario Applications, From Residential to Light Commercial
- Urban Residential+ Rooftop Solar. It improves self-consumption rate, smooths peak demand, and provides backup power during power outages.
- Harsh Climates (Cold, High Altitude, Hot Coastal Areas). Stable operation year-round even under extreme environmental conditions.
- Hotels/Farms/Light Commercial. Flexible scalability allows for smooth expansion to over 100 kWh as occupancy or production increases, avoiding the high costs of later expansion.
- Off-grid/Unstable grid. It provides continuous power to critical loads (e.g., security systems, routers, circulating pumps) to ensure uninterrupted operation.
