BIWATT Introduces Innovative Sodium-Ion Energy Storage Solutions with UL Certification

In a significant stride towards green energy innovation, BIWATT unveiled its latest sodium-ion energy storage solutions during the Intersolar Europe 2026 event. The company introduced two new battery models: the PowerNest R5 designed for residential use, and the PowerLake I3 tailored for commercial and industrial applications. This move not only expands BIWATT's portfolio in the sodium-ion battery market but also reflects its commitment to advanced energy storage solutions.

The PowerNest R5 is built on a cutting-edge platform to ensure optimal performance and safety in residential energy storage. Its modular scalability allows homeowners the flexibility to adjust their energy storage needs as required. Furthermore, the inclusion of intelligent battery optimization and active balancing technology makes it a smart choice for modern homes looking to maximize their energy efficiency.

For commercial and industrial sectors, the PowerLake I3 offers a robust solution that integrates seamlessly with solar energy systems. Its design focuses on flexible deployment options and smart maintenance features, catering to a wide range of energy storage requirements, including backup power and decentralized energy supplies.

Notably, BIWATT's proactive involvement in cell-level development sets it apart from traditional battery manufacturers. By establishing performance, safety, and reliability benchmarks during the initial design phases, the company has successfully developed a dedicated sodium-ion battery platform optimized for energy storage. This approach has allowed the organization to launch the R5 and I3 while continuously emphasizing safety. With ongoing UL1973 certification and UL9540A testing procedures, BIWATT assures customers of high safety standards for its products.

Owen, the CEO of BIWATT, expressed this commitment during the launch, stating that the process of energy storage involves much more than simply selecting a battery's chemical composition. "Our goal has been to deeply engage in innovation at the cell level and develop sodium-ion batteries specifically designed for energy storage applications. The release of the R5 and I3 models showcases our long-term dedication to this vision," he remarked.

As BIWATT's sodium-ion products are deployed across over 20 countries — primarily in Europe — they signal a growing commercial acceptance of sodium-ion energy storage technology. This increasing global footprint illustrates not just the urgency for innovative storage solutions but also the market's readiness to embrace alternative energy innovations.

BIWATT stands out as a leader in the digital green energy sector and a pioneer of sodium-ion technology. Their comprehensive ecosystem tailored for residential, mobility, and commercial applications incorporates everything from battery systems and sodium-ion optimized inverters to proprietary solutions like battery management systems (BMS), cloud platforms, and smart mobile applications. With a commitment to advancing the energy landscape, BIWATT continues to pave the way for a sustainable future.
