BlueTray™ 4000

The reliable, high power, rack-mounted sodium-ion battery pack.

The Benefits of Blue.

The sodium-ion cells in Natron’s unique battery chemistry are based on Prussian blue electrodes, which means they’re non-flammable, highly efficient and deliver significantly more life cycles than lead-acid or lithium-ion options.

The BlueTray™ 4000 features:

  • Safety and Sustainability —constructed using safe, commodity materials

  • Lower CAPEX and improved 5-year TCO compared to traditional batteries

  • Significantly improves PUE (Power Usage Effectiveness)—no dedicated cooling required

  • 0-99% SOC (State of Charge) in 8 minutes means quick return to service (for peak shaving, software defined power and other high cycle-rate applications)

  • 10x faster cycling ensures consistent availability

  • Frequent rapid charging does not affect battery performance

  • Half the footprint of lead acid batteries

  • UL 9540A cell test results show no thermal runaway even at the cell level.

Please note our batteries are not designed for, nor UL approved for consumer use, including residential or commercial solar power systems, off-grid power, automotive, marine or general DIY purposes.
