Sungrow Launches PowerStack 255CS to Revolutionize Commercial & Industrial Energy Storage

Hefei, China, April 11, 2025 – At the Global Renewable Energy Summit 2025, Sungrow, a global leader in PV inverters and energy storage, unveiled the PowerStack 255CS, a breakthrough liquid-cooled commercial and industrial (C&I) energy storage system. Designed to address surging global demand, the system combines cutting-edge efficiency, safety, and adaptability to accelerate sustainable energy adoption.

Rising C&I Energy Storage Needs

With C&I energy storage capacity projected to hit 46GWh by 2028, businesses increasingly seek solutions to reduce costs, stabilize grids, and integrate renewables. The PowerStack 255CS tackles challenges like EV charging demand spikes and grid instability through advanced technology.

314Ah Cells & Liquid Cooling Boost Performance

Featuring high-density 314Ah battery cells, the system offers 257kWh (2-hour) or 514kWh (4-hour) configurations per container. Sungrow’s AI-driven liquid-cooling technology slashes auxiliary power use by 33%, achieving over 90% round-trip efficiency and a 20-year lifespan.

Safety First: UL-Certified Protection

The PowerStack 255CS meets UL9540, NFPA855, and other global certifications. Multi-stage safeguards—from cell-level anomaly detection to fire suppression—ensure operational security.

Flexible Deployment & Rapid Installation

A pre-integrated EMS, PCS, and BMS simplify installation, while modular scalability supports projects from 257kWh to 6.4MWh. Pre-commissioned components enable fast grid connection.

Multi-Scenario Applications

• Standalone Storage: 100ms response time for daily frequency regulation revenue.

• PV Integration: AC/DC coupling maximizes solar utilization.

• EV Charging: Software-managed storage-charger coordination reduces grid strain.

• Microgrids: Transformer-free 400V AC output and seamless ATS transitions.

Global Reach & Service

Deployed in 1,000+ projects across Europe, Australia, and beyond, Sungrow’s solutions now include IEC/UL/AU-certified versions. With 520+ service outlets worldwide, Sungrow continues leading the charge toward a carbon-neutral future.
