The Polinovel 51.3V 50Ah rack-mounted sodium ion battery provides 2.565kWh of nominal energy in a compact module designed for backup power and modular energy storage applications.
With up to 100A discharge current, an 8,000-cycle design under specified test conditions, and discharge operation down to -40°C, it provides a flexible battery option for residential storage, communication backup and low-temperature power applications. Up to 20 batteries can be connected in parallel for greater system capacity.
The 2.565kWh battery module combines energy storage capacity with a compact rack-mounted structure, making it suitable for installations where system space and modularity matter.
Supports up to 100A maximum discharge current, providing stable power delivery for backup and energy storage applications with changing load demands.
Designed for discharge operation from -40°C to 60°C, extending battery usability in colder environments where temperature can limit conventional battery performance.
Connect up to 20 battery modules in parallel, allowing storage capacity to be expanded as backup duration or energy requirements increase.
