Table of Content [Hide]

    As companies and utilities adopt more renewable energy sources such as solar and wind, efficiency and reliability have become top priorities for energy buyers. Many European and U.S. procurement teams now prefer containerized battery energy storage systems because they offer faster deployment, stronger safety features, and better long-term cost savings.

    Our company specializes in 20ft and 40ft containerized LFP energy storage solutions, using advanced liquid cooling, integrated fire protection, and modular energy expansion to meet the needs of commercial, industrial, and utility-scale projects.


    What Is a Containerized Battery Energy Storage System?

    A containerized battery energy storage system is a complete, ready-to-deploy unit that houses all critical components inside a standard shipping container.


    Our brand’s solutions include:

    20ft BESS Container (1–3 MWh Class)

    • Energy Capacity: 1.0–3.0 MWh

    • Battery Type: LFP (Lithium Iron Phosphate)

    • Cooling System: Optional air cooling or liquid cooling

    • Protection Level: IP54–IP55

    • Ideal for: commercial loads, EV charging hubs, industrial peak shaving

    40ft BESS Container (3–5 MWh Class)

    • Energy Capacity: 3.0–5.0 MWh

    • Battery Type: LFP high-density modules

    • Cooling: High-efficiency liquid cooling system

    • Safety: Integrated fire detection + aerosol or gas fire suppression

    • Ideal for: utility-scale renewable projects, microgrids, grid support

    Core Built-In Components Across All Models

    • Intelligent Battery Management System (BMS)

    • EMS for real-time control and scheduling

    • PCS converter for AC/DC bidirectional power flow

    • HVAC or liquid cooling to maintain stable temperatures

    • Fire suppression systems with multi-level protection

    • Optional black start capability

    • Remote monitoring platform for 24/7 system control


    Why Our Containerized Battery Storage Is Highly Efficient

    1. High Efficiency with LFP Technology

    Our systems use A-grade lithium iron phosphate (LFP) cells, known for:

    • Round-trip efficiency: 88–95%

    • Cycle life: 6,000+ cycles

    • Greater resistance to thermal runway

    • Stable performance in most climates

    This combination ensures more stored energy can be delivered when needed, creating strong long-term economic returns.


    2. Rapid Deployment and Modular Expansion

    Our 20ft and 40ft BESS containers are designed for plug-and-play deployment.
    Key benefits include:

    • Factory-integrated systems reduce on-site construction

    • Standardized container footprint simplifies transport

    • Add more containers to scale from 1 MWh → 10 MWh → 50+ MWh

    • Fast commissioning with preset BMS/EMS configurations

    This makes our system ideal for EPC firms, industrial parks, and renewable developers who need a flexible and scalable solution.


    3. Lower Operating Cost with Liquid Cooling

    Our latest liquid cooling technology provides:

    • ±1°C temperature uniformity

    • Longer battery lifespan

    • Reduced energy consumption of HVAC

    • Lower risk of local overheating

    Compared with air cooling, liquid cooling systems maintain battery health more effectively—especially in high-temperature regions or during high power charging/discharging.


    4. Full Safety Protection for Industrial and Utility Use

    Every container includes:

    • Cell-level temperature and voltage monitoring

    • Gas, smoke, and thermal sensors

    • Multi-stage fire suppression systems

    • Automatic system shutdown and isolation

    • Optional water-mist systems for 40ft containers

    This allows buyers to operate in compliance with global standards including CE, UL, UN38.3, and IEC 62619.


    How Our Containerized Energy Storage System Works
