48KWh Commercial Energy Storage System - Reliable Power Solutions from China Suppliers & Factory for Retail Stores
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 & 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.
Supports essential loads such as refrigerated display cases, lighting, and POS systems, reducing electricity costs.
Releases stored energy during peak usage periods (such as weekends and holidays) to prevent circuit breakers from tripping due to overload.
Ensures uninterrupted power supply to cold chains and monitoring systems during sudden power outages, minimizing product loss and safety risks.
Integrates with solar power generation to create “carbon-neutral supermarkets,” enhancing brand image and attracting eco-conscious consumers.
