Deye Introduces Revolutionary C&I ESS Solution with Advanced PCS Technology

Designed for exceptional flexibility, reliability and smart energy control, it highlights Deye’s strong dedication to providing sustainable, high-efficiency power solutions for businesses worldwide.

Scalable Modular Architecture

This PCS module is most welcome for its highly scalable and modular combination design that offers flexible solutions tailored to a wide range of application needs. It allows up to 25 units to operate in parallel for a total output power of 2.5MW, and each PCS can connect with up to 16 battery racks, supporting diverse system scales – from small installations to large commercial or industrial projects. The architecture also supports hybrid operation modes, allowing seamless switching between on-grid and off-grid states via a Static Transfer Switch (STS). In addition, it can be integrated with diesel generators for emergency backup, ensuring uninterrupted power supply in critical or remote locations.

Extremely High Power Quality

The PCS module achieves up to 98.5% conversion efficiency, helping save more energy and making power conversion more effective than ever. Its advanced design can handle sudden power surges up to 170%, keeping the system running smoothly even under heavy loads. The system’s robust design also includes multiple protection mechanisms that safeguard against voltage and frequency changes, ensuring high power quality at all times.

Superior Durability

Built to withstand the harshest environments, the PCS features an IP65-rated enclosure that provides robust protection against dust and water intrusion. The corrosion-resistant housing and advanced thermal management system allow reliable operation in extreme temperatures ranging from -25℃ to 60℃. The durable structure, paired with components designed to withstand vibration, guarantees long-lasting and reliable operation in demanding industrial environments.

In addition, this system’s zero-export feature prevents reverse power flow and ensures grid stability, while the time-of-use optimization adjusts energy consumption based on tariff periods to reduce costs. By integrating these capabilities, it simplifies energy management while maintaining high performance and reliability. Deye’s C&I ESS solution empowers businesses to achieve energy independence, reduce operational expenses, and enhance grid resilience. Whether used for peak shaving, load shifting, or emergency backup, this advanced system enables enterprises to use clean energy with confidence and efficiency.
