MAYMUSE announced the official commissioning of its integrated “solar PV–energy storage–smart charging” microgrid station near the metro area at Huai De Zhong Road 42, Changzhou. Positioned as a user-side energy storage demonstration, the site leverages a vanadium flow battery (VFB) system as the core technology to provide convenient green charging services for residents in the old urban district while validating VFB performance in dense city-center energy scenarios.
The smart station makes efficient use of underutilized space around the metro vicinity, forming a replicable urban user-side energy solution. The installation includes:
- 120kW solar PV generation system
- 128kW / 896kWh vanadium flow battery energy storage system (approximately 7 hours of duration)
- 20 smart EV charging terminals

In operation, the station follows a “store solar during the day, discharge at peak demand” approach. According to the project information, the 896kWh storage capacity can support the equivalent of about 15 EV full charges, and during evening peaks it can independently support full-load operation of all 20 charging terminals. The project also reports a reduction of the local peak–valley load gap by around 15%, helping improve energy utilization and ease grid pressure.
MAYMUSE highlights three key advantages demonstrated by the VFB-based system:
- Intrinsic safety for dense urban areas
The system uses aqueous electrolyte, aiming to eliminate combustion and thermal runaway risks at the source—an important consideration for people-dense city-center environments. - Long service life to reduce lifecycle costs
The project cites >20,000 cycles and a capacity retention of 80%+ after 10 years. Under a high-frequency scenario of roughly one full cycle per day, the system is described as capable of operating for more than 27 years, reducing replacement frequency and long-term O&M costs. - High-capacity, long-duration load shifting
With multi-hour output, the system supports peak shaving and energy balancing, aligning renewable generation with charging demand and local consumption.
The station is also described as achieving 100% local consumption of onsite PV generation, enabling green charging services without additional grid expansion investment, and providing an average service level of around 80 EV charging sessions per day—helping address a gap in green charging accessibility in older urban districts.
MAYMUSE stated that the project model is now positioned for broader rollout, with plans to replicate and extend the approach across key cities in the Yangtze River Delta, and to expand into additional user-side scenarios such as industrial parks and transport hubs.
