WATT-TUNE Concludes Participation in SMART GRID EXPO

WATT-TUNE, a notable player in the energy sector, recently concluded its participation in the SMART GRID EXPO 2026, held from March 17 to March 19 at the Tokyo Big Sight. This exhibition served as a platform for WATT-TUNE, alongside partners like Eco-Kakou, GoodWe Japan, and REVIX JAPAN, to showcase the remarkable potential of low-voltage energy storage systems.

The primary focus of the exhibition was the innovative 49.9kW class low-voltage battery systems, which can be installed in spaces as small as approximately six tsubo (about 20 square meters). WATT-TUNE presented the advantages of these systems in stabilizing power supply and demand balances, positioning them as critical components in the future of decentralized energy infrastructure.

Key Highlights of the Low-Voltage Battery Systems

WATT-TUNE's display highlighted the versatility and scalability of its low-voltage battery solutions. These systems are not only practical for smaller plots of land that have been challenging to utilize effectively but also offer a pathway for larger-scale aggregation. By combining multiple systems, the aggregate output can exceed 1,000kW, allowing for significant contributions to overall energy resources.

The growing importance of energy storage systems is underscored by the accelerating integration of renewable energy and shifts in power demand structures. Notably, the low-voltage battery systems stand out for their ease of installation in compact areas, promoting participation from various land sizes in supporting the national power grid.

Why Low-Voltage Battery Systems Matter Now

The need for reliable Energy Storage Systems (ESS) has never been greater, thanks to the increasing adoption of renewable energy sources. Low-voltage battery systems present a solution for areas previously viewed as unsuitable for energy generation, making them indispensable in the quest for more comprehensive and stable power systems.

WATT-TUNE believes that the dual potential of starting small while contributing meaningfully to larger energy markets is a cornerstone of the value these systems provide.

Collaboration and Future Direction

The exhibition was realized through a joint effort with GoodWe Japan and REVIX JAPAN, creating a robust support structure for the low-voltage battery systems' introduction. GoodWe Japan supplies the battery systems while REVIX JAPAN manages planning and structural adjustments. WATT-TUNE takes on the role of aggregator, exploring the potential of these decentralized energy resources. Eco-Kakou is tasked with engineering, procurement, and construction (EPC) responsibilities, further strengthening the implementation framework.

Moving forward, WATT-TUNE is committed to expanding awareness and addressing inquiries regarding low-voltage battery systems. The company plans to enhance its proposals for the 49.9kW class installations and develop aggregation methods that allow for collective use of these systems to optimize land utilization and assure stability in the power grid.

Insights from WATT-TUNE

In a recent statement, Shun Inoue, CEO of WATT-TUNE, expressed the significance of the exhibition: "We aimed to clarify that low-voltage systems are not merely small devices but carry great potential as decentralized energy infrastructure. Our goal is to distribute these systems effectively and stabilize the power network while optimizing land use. We will continue to promote the societal integration of low-voltage storage solutions through enhanced collaborations with involved partners."
