Residential energy storage · In stock in Poland
The wait is over.
Home energy storage for the long term.
After a long wait, we are delighted to announce that AuroraCell Residential Energy Storage Systems are now in stock at our warehouse in Poland. Our sodium-ion RESS is here, bringing long-life energy storage closer to European homes and installation partners.
Thank you to everyone who has followed the development, asked questions and waited for this arrival. Having stock in Poland is an important step: homeowners, installers and distributors can now talk to us about a system from the available batch and plan their next project with our team.
Why NCO is ideal for residential energy storage
A home battery works quietly in the background, storing energy and releasing it when the household needs it. That makes durability, daily cycling and safety central to the choice. Sodium Chromoxide (NCO), the sodium-ion chemistry behind AuroraCell RESS, is a strong fit for exactly these priorities.

Built for years of everyday energy storage
Residential storage should be considered over decades. With an expected service life of 25–30 years, AuroraCell’s NCO platform is intended to serve as a lasting part of the home’s energy system. Longer useful life can reduce the need for battery replacement and spread the initial investment over more years of use.
Cycle it daily. Make more of your solar energy.
Store surplus solar electricity during the day and use it later, when household demand rises. A projected cycle life of more than 30,000 cycles makes NCO especially compelling for frequent charge-and-discharge operation. The goal is a battery you can use every day as part of a correctly sized and configured home energy system.
Our NCO cycle-life update explains the ongoing cell tests and the projections behind this long-life approach.
Safety at the heart of the system
For equipment installed at home, safety deserves as much attention as capacity. AuroraCell RESS combines NCO sodium-ion chemistry, an integrated battery management system and passive thermal design. Together, these form our ultra-safe design approach: chemistry, monitoring and protection developed for residential storage. Correct installation and operation within the specified limits remain essential.
European stock. A practical next step.
With RESS now at our Polish warehouse, we can discuss availability, delivery arrangements and the right configuration for your project. Whether you are a homeowner planning solar storage or an installer preparing a customer installation, our team can help check the battery, inverter and operating settings together.
Long life, frequent cycling and an emphasis on safety make Sodium Chromoxide a compelling choice for residential energy storage. We are excited to see the next installations take shape.
*The 25–30-year expected service life is a design expectation, not a warranty duration. The >30,000-cycle figure is a projection based on cell-level test data, not a completed 30,000-cycle test of the residential system. Actual service life and cycling performance depend on temperature, depth of discharge, charge/discharge rate and operating conditions. Applicable product documentation and warranty terms govern each supplied system.
