Across Europe, strengthening policy frameworks and volatile electricity prices are driving commercial and industrial (C&I) clients toward dependable energy storage to cut expenses and secure consistent power. From 2023 to 2030, the C&I energy storage sector is projected to grow at a remarkable 47% annually. The industry faces multiple hurdles and prospects, such as enabling accurate storage integration in combined PV-storage setups to avoid investment inefficiencies, maintaining a steady electrical environment to support uninterrupted operations, and offering seamless management from setup to maintenance.

To address these demands, Sungrow has launched the C&I PowerKeeper series, featuring an all-in-one DC-coupled system with modular architecture. It aims for zero waste in spending and green energy usage, guarantees zero disruption for C&I power needs, and provides a smooth product journey via seven enhanced touchpoints—boosting customer returns.

Zero Waste via Modular Design
PowerKeeper protects client investments through adaptable configurations. Built around a 12.5 kWh module, each hybrid inverter accommodates 50–1000 kWh storage with 2–8 hours duration. Scalability is enabled by parallel inverter connections, allowing owners—from small shops to large plants—to optimize each kilowatt-hour. This eliminates overcapacity typical in fixed solutions, matching capacity precisely and lowering upfront costs.

Zero Outage with Integrated ATS
Business continuity relies on stable electricity. PowerKeeper ensures uninterrupted functioning, even during grid failures, by switching to off-grid mode within 10 milliseconds. Its built-in automatic transfer switch handles up to 250 kW loads—enough for a 2,500 m² supermarket—without extra cabinets. This saves space and equipment expenses while assuring steady performance for various sites, from retail to industrial facilities.

7 Ups: Streamlined User Experience
The "7 Ups" framework simplifies key stages: Installation, Deployment, Commissioning, Operation, Maintenance, Profit, and Safety—making each safer, easier, and more lucrative.

Compact and Quick Setup
Installation is swift and straightforward. Options include a 12.5 kWh single module or 50 kWh pre-assembled stack, fitting tight corners or enabling setup within minutes. The design allows manual placement in confined areas or forklift use in open spaces.

Resilience in Harsh Conditions
Once installed, the system offers enduring reliability with IP66, C5, and 50 cm water immersion protection, alongside a –20°C to 55°C operating range, ≤60 dB noise, and Type I + II lightning resistance. It performs consistently in Nordic winters, Southern European heat, or corrosive Mediterranean coastal climates.

Comprehensive Safety Monitoring
PowerKeeper implements end-to-end security via 5D alerts (current, voltage, smoke, temperature, water) and triple-layer protection at cell, pack, and plant levels, ensuring appliance-grade safety for daily use.

AI-Optimized Revenue
Adaptable to PV & storage, EV charging, microgrids, and standalone C&I systems, PowerKeeper enables earnings through self-consumption, arbitrage, FFR, and demand management. AI-driven modes adjust strategies based on real-time pricing, generation, and load forecasts, helping clients capture maximum value effortlessly.

PowerKeeper Innovation: 007 and Profit Focus
With more than 1,000 global C&I storage projects and 200 in Europe, Sungrow has gained extensive insight into client requirements. The PowerKeeper series—embodying zero waste, zero outage, and seven upgrades—tackles challenges across the storage lifecycle. Sungrow continues to push innovation, supporting a carbon-neutral future for C&I sectors.
