TÜV Rheinland, an internationally recognized provider of testing, inspection and certification services, hosted the 2025 “All Quality Matters” Solar & ESS Congress and Award Ceremony in Changzhou, China. At the event, Deye’s 100 kW–2.5 MW modular commercial and industrial energy storage solution received the Innovation Award for its technological design, system performance, environmental adaptability, application maturity and sustainability.
The award reflects international recognition of Deye’s continued investment and technical progress in the commercial and industrial energy storage sector.
Deye’s award-winning solution consists of a 125 kW PCS module, a 200 kW MPPT module and a 500 kW STS module. This modular architecture balances installation and deployment efficiency with flexible expansion of system power and storage capacity. By redesigning core components and improving system-level integration, the solution introduces a new approach to intelligent integration and multi-energy coordination for C&I energy storage projects.
The system features an innovative three-port STS and a “five-in-one” PCS architecture. These technologies are designed to address long-standing challenges in commercial and industrial energy storage system design. Combined with advanced software algorithms, the architecture supports efficient, stable and coordinated system operation.
With its broad application range, proven deployment capabilities and environmental benefits, the solution supports energy-transition and power-system development goals. It can help businesses optimize energy costs, improve power-supply security and increase the use of renewable energy. Additional configurations are available through Deye’s commercial and industrial energy storage solutions.
The modular system has already been deployed in applications such as large manufacturing facilities and overseas mining microgrids. These projects include parallel 5 MW/10 MWh installations, demonstrating the solution’s ability to scale for larger commercial and industrial energy requirements.
In addition to improving clean-energy utilization and supporting energy conservation and emissions reduction, the system provides continuous green power through millisecond-level switching and off-grid recovery. These capabilities can help businesses strengthen energy independence and progress toward lower-carbon operations.
Looking ahead, Deye will continue investing in energy storage innovation and working with global partners to promote the large-scale, intelligent and sustainable deployment of ESS solutions. Through these efforts, Deye aims to contribute to a cleaner, more reliable and more resilient energy future.
