Across Europe, as policy support grows and electricity prices remain volatile, more commercial and industrial (C&I) customers are turning to reliable energy storage to cut costs and secure a steady power supply. From 2023 to 2030, the C&I energy storage market is projected to grow at an impressive 47% annually. The industry now faces both challenges and opportunities—such as deploying storage precisely in integrated solar-storage setups to avoid wasted investment, maintaining a stable power environment to ensure uninterrupted operations, and delivering a seamless experience across the entire product lifecycle from installation to operation and maintenance.
To meet these demands, Sungrow has launched the new C&I PowerKeeper series, combining a one-stop DC-coupled solution with modular architecture. The system delivers 0 Waste in both investment and green power usage, guarantees 0 Outage for industrial and commercial energy consumption, and ensures a worry-free user experience through 7Ups covering the full product journey—ultimately generating higher returns for customers.
PowerKeeper protects customer investments with highly flexible configurations. Built around a 12.5 kWh module, a single hybrid inverter supports storage capacities from 50 to 1000 kWh with 2 to 8 hours of duration. Multiple inverters can be paralleled for limitless expansion. This modular approach allows business owners—from small shops to large factories—to maximize the value of every kilowatt-hour. It effectively eliminates the over-sizing common in traditional fixed-capacity systems, ensuring precise capacity matching and lowering initial investment.
A reliable power supply is essential for any business. PowerKeeper ensures operations continue uninterrupted—even during a sudden grid failure. The system transitions seamlessly to off-grid mode in just 10 milliseconds, keeping all equipment running without disruption. Its built-in ATS can directly support loads of up to 250 kW, equivalent to the electricity needs of a 2,500 m² supermarket, with no extra ATS cabinet required. This saves both space and equipment costs while delivering continuous, stable power for everything from retail stores to manufacturing lines—giving customers total peace of mind.
The “7 Ups” concept ensures that every key phase—Installation, Deployment, Commissioning, Operation, Maintenance, Profit, and Safety—is easier, safer, and more profitable.
Fit in Corners, Install in a Coffee Break
PowerKeeper makes installation fast and effortless. Customers can choose between a 12.5 kWh single module or a 50 kWh pre-assembled stack, allowing them to maximize space efficiency or complete installation within a coffee break. The design supports easy manual handling in tight spaces and forklift movement in open areas.
Operates in Water Up to 50 cm Deep
Once installed, the system ensures long-term reliability with 50 cm water protection, IP66 and C5 ratings, an operating range from –20°C to 55°C, noise levels ≤60 dB, and Type I + II lightning resistance. Whether facing freezing Nordic winters, scorching Southern European summers, or salty coastal climates along the Mediterranean, PowerKeeper performs reliably under all conditions.
5D Alerts, Triple-Layer Protection, Cell-to-Plant Safety
PowerKeeper establishes end-to-end safety through 5D alerts (covering current, voltage, smoke, full-stack temperature, and water immersion) and triple-guard protection at the cell, pack, and plant levels. This multi-layered security delivers appliance-level confidence in daily operations.
AI-Driven Modes to Capture Every Cent
PowerKeeper supports diverse applications—including PV & storage, storage & EV charging, microgrid & backup, and stand-alone C&I ESS. It enables multiple revenue streams such as self-consumption, arbitrage, FFR, and demand control. With AI-driven operating modes that automatically optimize earnings based on real-time electricity prices, generation forecasts, and load predictions, customers can effortlessly maximize profitability.
With more than 1,000 C&I energy storage projects deployed worldwide—including 200 across Europe—Sungrow has provided end-to-end services to enterprises everywhere, gaining deep insight into customer needs. The new C&I PowerKeeper series, with its “0 Waste, 0 Outage, 7 Ups” promise, is designed to tackle pain points across the full storage lifecycle—from design and installation to commissioning and maintenance. Looking ahead, Sungrow remains dedicated to advancing the energy transition through continuous innovation—building toward a carbon-neutral future for commercial and industrial energy.
