48KWH Commercial All-in-One Energy Storage System

In the day-to-day operations of small retail stores, high electricity costs, significant losses from unexpected power outages, and difficulty in managing fluctuations in electricity consumption are the three main challenges. The 48kWh commercial energy storage system offers a comprehensive solution combining “peak shaving and valley filling,” “emergency backup,” and “smart management,” providing retail stores with a low-cost, highly reliable, and eco-friendly power solution that helps reduce operating costs and improve efficiency.

  • Rated Voltage 460V
  • Cell 3.2V-105AH
  • Rated Capacity 48KWH
  • Solar Charger Current 50A
  • AC-DC Charger Current 20A

System Advantages: Safe, Flexible, and Easy to Maintain
Safe and reliable, with a lifespan of up to 10 years
Utilizes lithium iron phosphate (LFP) batteries, which are heat-resistant and explosion-proof, making them ideal for high-traffic environments such as supermarkets.
The Battery Management System (BMS) monitors voltage and temperature in real time and supports three-level protection (overcharge, over-discharge, and short circuit), ensuring stable system operation with a cycle life exceeding 5,000 cycles.
Modular Design, Installed in 1 Day
The system integrates battery cabinets, inverters, and an Energy Management System (EMS) into a single unit, allowing for flexible deployment in spaces such as warehouses or electrical rooms.
Off-grid mode requires no modification to existing electrical circuits; after installation, the display screen immediately shows power consumption data and other metrics.
Smart Scheduling: Hassle-Free and Cost-Effective
The EMS system automatically optimizes charging and discharging strategies based on data such as the supermarket’s electricity usage patterns, electricity pricing policies, and PV output, eliminating the need for manual intervention.
For example: During summer when air conditioning loads are high, the system prioritizes discharging stored energy; during winter off-peak hours, it increases charging to prepare for peak demand periods such as the Spring Festival.
Typical Scenarios: Covering All Electricity Needs of Retail Stores
Daily Operations: Supports essential loads such as refrigerated display cases, lighting, and POS systems, reducing electricity costs;
Promotional Events: Releases stored energy during peak usage periods (such as weekends and holidays) to prevent circuit breakers from tripping due to overload;
Emergency Scenarios: Ensures uninterrupted power supply to cold chains and monitoring systems during sudden power outages, minimizing product loss and safety risks;
Green Transition: Integrates with solar power generation to create “carbon-neutral supermarkets,” enhancing brand image and attracting eco-conscious consumers.
