Driven by Europe\u2019s 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 system<\/strong>and 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%.<\/p>\n\n\n\n

Core Challenges & Solutions\uff1a<\/strong><\/h5>\n\n\n\n

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 \u2013 Energy Storage \u2013 Load\" was established.<\/p>\n\n\n\n

Highlights of Technical Breakthroughs\uff1a<\/strong><\/h5>\n\n\n\n
    \n
  • Flexible High-Capacity Stacking\uff1a<\/strong>\u00a0Each 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.<\/li>\n\n\n\n
  • Simple and Efficient Deployment\uff1a<\/strong>The revolutionary wiring-free modular design enables plug-and-play installation, cutting the overall system installation time by 60%.<\/li>\n\n\n\n
  • Strong Adaptability to Harsh Environments\uff1a<\/strong>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\u00b0C to +55\u00b0C.<\/li>\n\n\n\n
  • Complete Safety Certifications\uff1a<\/strong>It has obtained authoritative international safety certifications including CE, IEC 62619, UKCA and UN38.3.<\/li>\n<\/ul>\n\n\n\n
    Intelligent Dispatching and High Reliability Assurance\uff1a<\/strong><\/h5>\n\n\n\n

    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:<\/p>\n\n\n\n

      \n
    • Real-time Monitoring and Optimization\uff1a<\/strong>Deeply integrated into the supermarket\u2019s 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.<\/li>\n\n\n\n
    • Multiple Safety Protections\uff1a<\/strong>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.<\/li>\n<\/ul>\n\n\n\n

      The successful large-scale application of Enershare\u2019s high-voltage stacked lithium battery solution in Europe\u2019s 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.<\/p>\n\n\n\n

      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.<\/p>\n\n\n\n
