BIWATT Expands Its Sodium-Ion Energy Storage Offerings

On June 25, 2026, BIWATT made a significant announcement at Intersolar Europe 2026, unveiling its latest energy storage solutions: the PowerNest R5 for residential use and the PowerLake I3 designed for commercial and industrial applications. This launch marks an important step in enhancing BIWATT's lineup of sodium-ion energy storage systems tailored for both home and business environments.

Unlike traditional battery integration methods, BIWATT has taken an active role in cell-level development, establishing performance, safety, and reliability criteria early in the product development process. This innovative approach has enabled the creation of a specialized sodium-ion battery platform specifically optimized for energy storage applications.

The R5 and I3 models signify BIWATT's ongoing commitment to advancing the commercialization of sodium-ion energy storage. Previously introduced models, including the rack-mounted PowerNest R2 and the stackable PowerNest R3, are already seeing successful deployment in international markets, reinforcing the growing acceptance of sodium-ion technology.

The PowerNest R5 leverages the same foundational technology as its predecessors but offers improved modular scalability, intelligent battery optimization, and active balancing technology suited for residential energy storage applications. Meanwhile, the PowerLake I3 expands this technology into the commercial and industrial sectors, providing flexible operational options and intelligent maintenance features for solar plus storage systems, emergency power supplies, and decentralized energy projects.

To support future global market expansion, BIWATT is accelerating the UL1973 certification and UL9540A testing for its sodium-ion products. This commitment underscores the company's dedication to high safety standards. BIWATT's CEO, Owen, emphasized the distinction of energy storage beyond just the choice of battery chemistry, stating, "Our focus has been on engaging deeply in innovations at the cell level, developing sodium-ion batteries specifically for energy storage applications. The launch of R5 and I3 reflects this long-term commitment."

Today, BIWATT's sodium-ion solutions are in use across more than 20 countries, predominantly in Europe, showcasing the increasing commercial proliferation of sodium-ion energy storage technology. With a vision for the future and an established track record of innovation, BIWATT is poised to continue leading in the sodium-ion energy storage market.
