Across Europe, strengthening policy support and ongoing electricity price volatility are driving more commercial and industrial (C&I) customers toward reliable energy storage to reduce costs and ensure a stable power supply. From 2023 to 2030, the C&I energy storage market is expected to grow at a remarkable annual rate of 47%. This growth brings both opportunities and challenges—including deploying storage efficiently within integrated solar-storage systems to prevent wasted investment, maintaining a stable power environment for uninterrupted operations, and delivering a smooth experience across the entire product lifecycle, from installation to operation and maintenance.

To address these needs, Sungrow introduces its new C&I PowerKeeper series, which combines a one-stop DC-coupled solution with a modular design. The system achieves Zero Waste in both investment and green power usage, guarantees Zero Outage for industrial and commercial energy consumption, and ensures a worry-free user experience through 7 Ups that cover the entire product journey—ultimately delivering higher returns for customers.

Zero Waste Through Modular Design

PowerKeeper safeguards customer investments with highly flexible configurations. Built around a 12.5 kWh module, a single hybrid inverter supports storage capacities ranging from 50 kWh to 1000 kWh, with duration options from 2 to 8 hours. Multiple inverters can be paralleled for virtually unlimited expansion. This modular design allows businesses—from small shops to large factories—to maximize the value of every kilowatt-hour. It effectively eliminates the over-sizing typical of traditional fixed-capacity systems, ensuring precise capacity matching and reducing initial investment.

Zero Outage with Built-in ATS

A reliable power supply is critical for any business. PowerKeeper ensures continuous operation—even during sudden grid failures. The system transitions seamlessly to off-grid mode in just 10 milliseconds, keeping all equipment running without interruption. Its built-in Automatic Transfer Switch (ATS) directly supports loads of up to 250 kW—equivalent to the electricity needs of a 2,500 m² supermarket—without requiring an additional ATS cabinet. This saves both space and equipment costs while providing stable, continuous power for everything from retail stores to manufacturing lines, offering customers complete peace of mind.

7 Ups: A Smoother Journey at Every Stage

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 simple. Customers can choose between a 12.5 kWh single module or a 50 kWh pre-assembled stack, enabling them to optimize space or complete installation in the time it takes to enjoy 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 delivers long-term reliability with 50 cm water protection, IP66 and C5 ratings, an operating temperature 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—along with triple-layer protection at the cell, pack, and plant levels. This multi-layered security provides 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.

PowerKeeper Innovation: Delivering Ace 007, Ace Profit

With over 1,000 C&I energy storage projects deployed globally—including 200 across Europe—Sungrow has provided end-to-end services to enterprises worldwide, 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 committed to advancing the energy transition through continuous innovation, building toward a carbon-neutral future for commercial and industrial energy.
