Sungrow Unveils PowerKeeper Series at European CI ESS Summit

On November 27, Sungrow showcased its latest energy storage solution, the PowerKeeper Series, during the European CI Energy Storage Solutions (ESS) Summit held in Como, Italy. This cutting-edge solution promises to revolutionize the commercial and industrial energy landscape by offering a unified, modular design that emphasizes efficiency and user-friendliness.

The Concept Behind PowerKeeper

Central to the PowerKeeper Series is Sungrow’s innovative "Ace 007, Ace Profit" approach, aimed at achieving zero waste and zero interruptions while ensuring a seamless experience for businesses. This initiative is critical as Europe's energy storage capacity for commercial and industrial use is projected to grow exponentially, necessitating robust solutions.

Sungrow anticipates that by 2034, the region's CI storage capacity will have increased by a staggering 13 times to 33 GW/77 GWh, according to Wood Mackenzie. With rising electricity prices and a pressing need for resilience in energy supply, businesses are prioritizing cost management and energy reliability. The PowerKeeper Series is designed to address these challenges, offering an effortless lifecycle experience from installation to ongoing operation and maintenance.

Key Features of PowerKeeper

Modular and Scalable Design

The PowerKeeper solution is built with a modular design of 12.5 kWh, making it flexible and adaptable for various business environments. A single hybrid inverter can support capacities ranging from 50 to 1,000 kWh for durations of 2 to 8 hours. Businesses can connect multiple inverters, allowing for scalable installations suitable for both small workshops and large factories, ensuring precise adaptability of capacities and cost efficiency.

Quick and Easy Installation

PowerKeeper can be installed in as little time as a coffee break, designed for rapid, hassle-free deployment. Clients have the option to start with a single module or stack up to 50 kWh, making the most of every inch of space available. Its lightweight design allows for manual handling in tight spaces, or forklift operation in larger areas, further streamlining the installation process.

Resilient and Reliable

Once operational, the PowerKeeper system has the capability to function even under 50 cm of water, boasting an IP66 rating for water resistance. It operates effectively in a wide temperature range from -20°C to 50°C and comes equipped with lightning protection. This resilience ensures that whether faced with bitter winters in Northern Europe or scorching summers in the south, the PowerKeeper remains a reliable energy partner.

Comprehensive Safety Measures

Safety is paramount in the PowerKeeper design, which features a comprehensive monitoring system known as the 5D Alert system, which includes cellular monitoring and high-temperature detection to safeguard against malfunctions. This system provides peace of mind for users, ensuring continuous protection from the unit to the grid.

AI-Driven Efficiency

The PowerKeeper also incorporates artificial intelligence capabilities that optimize operations based on real-time electricity pricing, production forecasts, and load predictions. This not only simplifies management but also maximizes profitability for businesses, allowing diverse applications from photovoltaic systems to standalone energy storage.

The Summit and Future Prospects

The European CI ESS Summit was an event that saw over 200 leaders gather to discuss the pressing need for cost-effective, flexible, and low-carbon energy solutions. The event facilitated expert discussions on the unique energy needs across different sectors and regulatory landscapes in Europe, reinforcing Sungrow's role in moderating and decarbonizing the CI energy landscape.

Sungrow is already making strides in this arena, having executed over 1,000 energy storage projects worldwide, and 200 of those in Europe, ranging from autonomous ESS projects to hybrid systems. The company is well-positioned to assist partners navigating this rapidly evolving market.
