Driven by Europe’s energy transition and carbon neutrality goals, a well-known German supermarket recently announced that its store has successfully deployed Enershare energy storage systems.High-voltage stacked lithium battery energy storage systemand an in-depth integration solution with Deye three-phase photovoltaic inverters. Adopting an all-in-one solution integrating "photovoltaics + energy storage + intelligent power distribution", the supermarket has raised its self-sufficiency rate of electricity by 45% and cut annual energy costs by 30%.

Core Challenges & Solutions：

Supermarkets are characterized by high energy consumption and volatile power loads (largely driven by cold chain equipment), which create stringent demands for continuous, cost-effective power supply. To address these issues, the supermarket innovatively deployed three parallel banks of 8-layer Enershare high-voltage stacked lithium battery modules. Combined with high-performance Deye inverters, an intelligent power flow optimization system of "Photovoltaic – Energy Storage – Load" was established.

Highlights of Technical Breakthroughs：

• Flexible High-Capacity Stacking： Each Enershare high-voltage stacked lithium battery module has a capacity ranging from 4.8 kWh to 25.6 kWh, supporting flexible stacking of 2 to 8 layers. For this deployment, an 8-layer stack configuration is adopted with a capacity of 25.6 kWh per bank. Three banks are connected in parallel, delivering a total system capacity of 76.8 kWh.
• Simple and Efficient Deployment：The revolutionary wiring-free modular design enables plug-and-play installation, cutting the overall system installation time by 60%.
• Strong Adaptability to Harsh Environments：The system carries an IP65 high protection rating and built-in module-level fire prevention mechanism, ensuring stable and reliable operation over a wide temperature range of -10°C to +55°C.
• Complete Safety Certifications：It has obtained authoritative international safety certifications including CE, IEC 62619, UKCA and UN38.3.

Intelligent Dispatching and High Reliability Assurance：

Meeting the demand for uninterrupted supermarket operation is the core priority. The intelligent Battery Management System (BMS) equipped in the system provides multi-layer protection as follows:

• Real-time Monitoring and Optimization：Deeply integrated into the supermarket’s Energy Management System (EMS) via CAN/RS485 communication protocols, it monitors battery status (SOC, SOH, temperature, etc.) in real time and dynamically optimizes charging and discharging strategies based on load forecasting and electricity price signals.
• Multiple Safety Protections：Equipped with IP65 protection, module-level fire protection, as well as real-time monitoring and alarms for faults such as overheating, overcharging and short circuits, it supplies uninterrupted power protection for critical cold chain equipment and other loads.

The successful large-scale application of Enershare’s high-voltage stacked lithium battery solution in Europe’s retail industry not only verifies its outstanding performance in cutting operating costs and enhancing energy resilience, but also offers a replicable energy-saving and efficiency-improving solution for supermarkets and other similar high-energy-consumption commercial scenarios. This case fully illustrates how technological innovation drives in-depth integration between commercial operation and sustainable energy systems.

At present, taking the European market as its strategic foothold, Enershare cooperates with global partners including Deye to build a more efficient and resilient commercial energy ecosystem, continuously injecting core momentum for green transition into the global retail industry and broader commercial sectors.
