Sungrow on Wednesday introduced its new commercial and industrial energy storage solution, the PowerKeeper Series, at its European C&I ESS Summit, as businesses across Europe look to boost resilience and manage rising power costs.
The summit, held in the northern Italian city of Como, brought together more than 200 business leaders, technology partners and media representatives to discuss Europe's growing demand for flexible, cost-efficient and low-carbon energy solutions.
Panel discussions focused on differences in business needs and regulatory frameworks across European markets, offering participants insights into growth opportunities and emerging strategies in the region’s commercial and industrial energy sector.
Sungrow said in a statement that the PowerKeeper Series is a DC-coupled, modular energy storage system built on its "Ace 007, Ace Profit" concept, which aims to deliver zero waste, zero outage, and a hassle-free experience for businesses through seven key advantages.
Designed for customers ranging from small commercial facilities to large industrial sites, the system is built around 12.5 kilowatt-hour modules.
A single hybrid inverter can support 50-1,000 kilowatt-hours of storage for durations of two to eight hours, with additional inverters allowing systems to be expanded as demand grows.
According to the company, the PowerKeeper system can switch to off-grid operation within 10 milliseconds during a power outage. Its built-in automatic transfer switch supports loads up to 250 kilowatts without requiring additional cabinets, helping reduce space requirements and installation costs.
Sungrow said the system can be deployed either as individual 12.5-kilowatt-hour modules or as a 50-kilowatt-hour pre-assembled stack designed for fast installation in confined spaces.
The company added that the system is engineered to operate in water depths of up to 50 centimeters and in harsh environments, with an operating temperature range from minus 20 to 50 degrees Celsius, IP66 protection, C5 corrosion resistance and lightning protection.
The PowerKeeper Series features what Sungrow describes as a "cell-to-station" safety architecture, with multi-dimensional monitoring and layered protection at the cell, pack and station levels. The system includes so-called 5D alerts and triple-guard protection to monitor current, voltage, cell temperature, high-temperature conditions and safety signals, enhancing operational safety.
Powered by AI-driven controls, the system supports multiple revenue streams, including self-consumption, energy arbitrage, fast frequency response (FFR) and demand control.
Sungrow said the software automatically optimizes revenue strategies based on real-time electricity prices, generation forecasts and load predictions.
The company said PowerKeeper is designed for a broad range of applications, including solar-plus-storage projects, energy storage combined with electric vehicle charging, microgrids, backup power and stand-alone commercial and industrial installations.
Sungrow said it has deployed more than 1,000 commercial and industrial energy storage projects worldwide, including about 200 in Europe, across stand-alone systems, solar-plus-storage installations and integrated projects combining solar power, storage and EV charging.
