Driven by Europe's energy transition and carbon neutrality goals, a well-known German supermarket recently announced that its stores have successfully deployed the deep integration of Enershare's high-voltage stacked lithium battery energy storage system and Deye's three-phase photovoltaic inverter . Through the integrated solution of "photovoltaic + energy storage + intelligent power distribution" , it has achieved a 45% increase in electricity self-sufficiency and a 30% reduction in annual energy costs.

Core challenges and solutions:

The supermarket format has the characteristics of high energy consumption and large fluctuations in power load (especially affected by cold chain equipment), which poses severe challenges to the continuity and economy of power supply. To this end, the supermarket innovatively adopted a solution of three groups of 8-layer Enershare high-voltage stacked lithium battery modules in parallel, combined with high-performance Deye inverters, to build an intelligent "light-storage-load" power flow optimization system.

Highlights of technological breakthroughs:

• Flexible high-capacity stacking: Enershare's high-voltage stacked lithium battery has a single module capacity range of 4.8kWh to 25.6kWh, supporting flexible stacking of 2 to 8 layers. This deployment uses 8 layers of stacking, with a single group capacity of 25.6kWh, and three groups in parallel to achieve a total system capacity of 76.8kWh .

• Simple deployment and efficiency: The revolutionary wiring-free modular design enables “plug and play” and reduces the installation time of the entire system by 60% .

• Adaptability to harsh environments: The system has IP65 high-level protection and a built-in battery module-level fire protection mechanism to ensure stable and reliable operation in a wide temperature range of -10℃ to +55℃.

• Comprehensive safety certification: It has passed CE, IEC 62619, UKCA, UN38.3 and other authoritative international safety standards certification.

Intelligent scheduling and high reliability guarantee:

Meeting the uninterrupted operation needs of supermarkets is the core requirement. The intelligent battery management system (BMS) equipped in the system provides multiple guarantees:

• Real-time monitoring and optimization: Deeply integrated into the supermarket energy management system (EMS) through CAN/RS485 communication protocol, real-time monitoring of battery status (SOC/SOH/temperature, etc.), and dynamic optimization of charging and discharging strategies based on load forecasting and electricity price signals.

• Multiple safety protections: Integrated IP65 protection, module-level fire protection, and real-time monitoring and alarm functions for over-temperature, over-charging, short-circuit and other faults, providing uninterrupted power protection for key cold chain equipment and other loads.

The successful large-scale application of Enershare's high-voltage stacked lithium battery solution in the European retail industry not only verifies its outstanding results in reducing operating costs and improving energy resilience, but also provides a highly replicable energy efficiency improvement path for supermarkets and similar high-energy consumption commercial scenarios. This case deeply reflects how technological innovation drives the deep integration of commercial operations and sustainable energy systems.

Currently, Enershare is using the European market as a strategic fulcrum and working with global partners including Deye to build a more efficient and resilient commercial energy ecosystem, continuously injecting core momentum for green transformation into the global retail industry and even the broader business sector.
