As India’s commercial and industrial (C&I) sector increasingly embraces clean energy to reduce operational costs and improve energy resilience, battery energy storage systems (BESS) are becoming an essential component of modern power infrastructure.  Addressing this growing demand, Sungrow has introduced the PowerStack 255CS Energy Storage System, a fully integrated solution designed to deliver high efficiency, operational reliability, and simplified deployment for small and medium-sized industries.

Unveiled at REI Expo 2025, the PowerStack 255CS features a 125 kW / 255 kWh (2-hour) configuration, offering businesses an effective solution for optimizing energy usage, supporting peak shaving, and improving power reliability. Designed as a pre-installed and pre-commissioned system, the solution significantly reduces installation time, minimizes on-site engineering requirements, and simplifies overall project execution, enabling faster deployment and lower implementation costs.

One of the defining strengths of the PowerStack 255CS is its intelligent thermal management system. Leveraging AI-driven technology, the system reduces daily heat loss by up to 33%, contributing to higher operational efficiency and improved energy performance. Its advanced liquid cooling architecture maintains a temperature variation of just 2.5°C, ensuring uniform battery operating conditions that enhance system stability, improve charging and discharging efficiency, and extend battery lifespan.

Safety is another key pillar of the PowerStack 255CS design. The system integrates a comprehensive three-level fire protection mechanism alongside early thermal runaway detection and multi-level overcurrent protection across the battery pack (PACK), rack (RACK), and power conversion system (PCS). These integrated safety features provide robust protection against operational risks while ensuring dependable performance in demanding industrial environments.

The launch of the PowerStack 255CS further strengthens Sungrow’s growing presence in India’s renewable energy sector. Backed by a 25 GW manufacturing facility in India, and more than 75 GW of cumulative PV inverter shipments in the country, the company continues to support India’s transition toward cleaner and more reliable energy infrastructure. With a global portfolio exceeding 1,000 energy storage deployments across commercial, industrial, and utility-scale projects, Sungrow combines extensive industry experience with continuous technological innovation to deliver advanced energy storage solutions tailored to evolving market requirements.The PowerStack 255CS reflects Sungrow’s commitment to providing intelligent, safe, and high-performance energy storage systems that enable businesses to improve energy efficiency, strengthen operational resilience, and accelerate the adoption of sustainable energy solutions.
