  • For energy storage with solar, There are following problems of Li-ion battery in Year 2026:
  • Solar Li-ion batteries are unsafe, posing risks and hazards of overheating, explosion, and fire.
  • Solar Li-ion battery power will decrease in cold winters.
  • Solar Li-ion battery power is limited in hot summers.
  • Solar Li-ion battery power supply is unstable in high-altitude areas.
  • Solar Li-ion batteries cannot withstand wind, rain, snow and dust corrosion.
  • To meet the needs for “safe 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 8KWH Solar Sodium Ion Battery.
  • In 2026, we have 1 models of 8KWH solar sodium ion batteries: 51.2V160AH solar sodium ion battery (Rack Mount)
  • This model of 51.2V100AH solar sodium ion battery are primarily designed for solar home and solar site, providing a safe, reliable, stable, and environmentally friendly power supply to meet the needs for safe, power anytime, anywhere.
  • The biggest advantage of the 8KWH Solar Sodium Ion Battery is that, instead of “unsafe Solar Li-ion batteries,” Solar 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 solar sodium ion battery?

  • Safest NFPP SIB technology, never fire nor explosion

Based on sodium Ion battery technology, solar 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.

51.2V160KWH solar 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

51.2V160AH solar 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,IP20 protection,rack mount design.

  • Flexible expansion to meet ever-growing needs.

51.2V160AH solar sodium ion battery supports up to 16 blocks in parallel, which means total system is 16 *8.23KWH=131.68KWH.

  • Multi-Scenario Applications
  • 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.

Our understandings of 51.2Vsolar sodium ion battery

The 51.2V solar sodium-ion battery must be a safe battery that can withstand the challenges of high and low temperature operating environments, as well as the instability brought by outdoor deployment and harsh weather.

The 51.2V solar sodium-ion battery must be easy to install and maintain, for example,its clear cabling and reserved maintenance channels facilitate long-term maintenance, ensure system safety, and facilitate future expansion.

The 51.2V solar sodium-ion battery must provide reliable power for home users, commercial users, and special application scenarios such as high altitude and frigid regions, allowing users to use it with peace of mind and worry-free power supply.
