As Japan's bustling capital, Tokyo is at the forefront of the global energy transition. The Tokyo Metropolitan Government's aggressive "Carbon Half" goal by 2030 has catalyzed a massive shift toward sophisticated energy management. DC-Coupled Energy Storage Systems (ESS) have emerged as the preferred choice for Tokyo's commercial and industrial (C&I) sectors due to their superior efficiency in capturing solar energy. Unlike AC-coupled systems, our Tokyo-optimized DC-coupled systems minimize conversion losses by allowing PV power to flow directly into the battery, a critical factor for land-scarce Tokyo where every watt counts.
In Tokyo's high-density districts like Shinjuku and Marunouchi, our systems help enterprises reduce peak demand charges, optimizing energy costs amidst Japan's rising utility rates.
DC-coupled architecture reduces the number of required inverters, making it an ideal compact solution for Tokyo's constrained industrial rooftops and basement energy rooms.
Our Tokyo branch supports the integration of ESS into Virtual Power Plants (VPP), enhancing the city's grid stability during peak summer and winter loads.
Hunan June Power Technology Co., Ltd. is a national high-tech enterprise located in Jiangbei New Area, Nanjing. June focuses on the R&D, production, and sales of PCS, Hybrid Inverters, Energy Storage Systems (ESS), and Microgrid Systems, while also engaging in the investment, development, and construction of photovoltaic and energy storage power plants.
The company operates an R&D and manufacturing base of over 100,000 m², and its products are distributed in more than 100 countries. To deliver efficient, localized technical support, we have established strategic branches in Tokyo, Los Angeles, and Warsaw. Our Tokyo presence ensures that we meet the rigorous Japanese safety standards (METI/JET) and provide immediate field service to our Japanese partners.

The energy landscape in Tokyo is uniquely challenging. High electricity prices and a dense urban environment necessitate high-efficiency energy storage. Our DC-coupled energy storage systems allow for "over-provisioning" of solar arrays—a common practice in Tokyo to maximize output during the city's varying weather patterns. By coupling at the DC level, energy can be diverted to the battery without passing through an AC inverter first, reducing conversion losses by approximately 3-5% compared to AC-coupled alternatives.
Furthermore, the Japanese market demands extreme reliability. Our Tokyo-based engineering team works closely with local installers to ensure that every ESS unit meets the stringent seismic and fire safety regulations required for installation in Tokyo's metropolitan buildings. From Saitama to Kanagawa, our systems are powering the next generation of smart factories and eco-friendly data centers.
Trending now in the Tokyo market is the integration of DC-coupled systems with EV charging infrastructure. As Tokyo transitions to electric mobility, our systems act as a DC-buffer, allowing high-speed EV charging without straining the local distribution transformers, thus avoiding expensive grid upgrades for facility owners.
