On November 27, Sungrow unveiled its latest commercial and industrial (C&I) energy storage innovation, the PowerKeeper Series at the Sungrow European C&I ESS Summit in Italy. This new series introduces a one-stop, DC-coupled solution with a modular design, built around Sungrow’s forward-thinking concept, “Ace 007, Ace Profit.” The approach focuses on delivering zero waste, zero outage, and zero hassle, ensuring maximum reliability and simplicity for businesses through seven key advantages.
The Critical Importance of C&I Energy Storage for a Sustainable European Future
Sungrow’s launch comes at a pivotal time for Europe’s energy landscape. According to Wood Mackenzie, the continent’s C&I energy storage capacity is projected to expand 13-fold by 2034, reaching 33 GW/77 GWh. With energy prices fluctuating and resilience becoming a top business priority, companies are increasingly focused on energy cost control, self-consumption, and uninterrupted power supply. To meet these demands, next-generation storage systems like PowerKeeper must offer seamless performance across the entire lifecycle from design and installation to operation and maintenance, while supporting diverse industries with varying consumption patterns and financial goals.
The Future of C&I innovation – the PowerKeeper Series
In response, the PowerKeeper series, built on the ‘Ace 007, Ace Profit’ concept, offers flexible energy storage with a 12.5 kWh modular design. A single hybrid inverter supports 50–1000 kWh capacity for 2–8 hours, and multiple inverters can be connected for flexible expansion. This scalability suits everything from small shops to large factories, ensuring precise capacity matching, eliminating oversizing, and reducing upfront costs. For uninterrupted operations, PowerKeeper can switch to off-grid modes in 10 milliseconds. Its built-in ATS supports up to 250 kW load enough for a 2,500 m² supermarket, without extra cabinets, saving space and cost.
The concept redefines energy storage with simplicity, safety and profitability at its core:
- Fit Even in Corners and Install in A Coffee Break:
PowerKeeper keeps installation effortless and fast. Customers can choose either a 12.5 kWh single module or a 50 kWh pre-built stack, which supports both maximizing every space centimeter and fast installation within one coffee break. Its design supports easy manual handling in tight spaces and forklift operations in open areas. - Operate in Water up to 50cm Depth: Once installed, the system delivers long-term reliability with 50 cm water protection, IP66, C5, a –20°C to 50°C operating range, and Type I + II lightning resistance. Whether facing the freezing winters of Northern Europe, the scorching summers of Southern Europe, or the salty, corrosive coastal climates along the Mediterranean, PowerKeeper remains stable and dependable in all conditions.
- 5D Alerts, Triple-guard Protection, Cell-to-Plant Security: PowerKeeper establishes a comprehensive cell-to-station security system through 5D alerts (current, voltage, cell temperature, NTC high-temperature detection, and safety detector), and triple-guard protection at the cell, pack, and station. This delivers appliance-level peace of mind for customers in daily operation.
- AI-driven Modes, Capture Every Cent: PowerKeeper adapts to diverse applications, including PV & ESS, ESS & EV charger, microgrid & backup, and stand-alone C&I ESS. PowerKeeper supports multiple revenue streams, including self-consumption, arbitrage, FFR, and demand control. With AI-driven modes that automatically optimize revenue strategies based on real-time electricity prices, generation forecasts, and load predictions, it enables customers to effortlessly maximize profitability.
This concept addresses pain points across the entire lifecycle and strengthens Sungrow’s C&I portfolio, reinforcing its leadership and commitment to a carbon-neutral commercial and industrial future.
Exclusive Discussion and Insights at Sungrow’s European C&I ESS Summit
