A liquid-cooled energy storage system uses a coolant loop to transfer heat away from battery cells, keeping them within the ideal temperature range.
For a 3.35MWh capacity container, this allows high-power operation while maintaining safety and cycle life — a crucial advantage for large renewable and grid projects.

Types of Large-Scale Energy Storage Systems

• Air-Cooled ESS (100kWh–5MWh): Easier maintenance, suitable for mild climates.

• Liquid-Cooled ESS (215kWh–3.35MWh): Better performance in high-density, high-temperature settings.

• Hybrid & Customized Systems: Combining modular units for flexible grid services.

The 3.35MWh liquid-cooled design provides a balance between energy density, durability, and cost-effectiveness.

Features of the 3.35MWh ESS

• High Thermal Efficiency – Liquid circulation maintains temperature uniformity across all cells.

• Long Service Life – More than 8,000 cycles, designed for 15+ years of operation.

• Smart Control System – Integrated EMS and BMS enable remote monitoring.

• Safety Mechanisms – Equipped with multi-level protection and automatic fault detection.

Applications of 3.35MWh Liquid-Cooled ESS

• Grid frequency regulation and voltage stabilization.

• Renewable integration for solar/wind farms.

• Industrial backup and energy cost optimization.

• Island microgrids and off-grid power supply.

Paired with systems like Dagong ESS 5MWh Air-Cooled Containers, these units create hybrid storage clusters for diverse climate and usage conditions.

Price of 3.35MWh ESS

The cost of energy storage systems for renewable energy integration depends on several factors, including system capacity, storage duration, battery type, control software, installation conditions, and auxiliary equipment.
Pricing is usually quoted under international trade terms such as EXW, FOB, or CIF, depending on project location and logistics preferences.
For a tailored quotation based on your specific project needs, it's best to consult directly with the supplier.

How to Select the Right Liquid-Cooled ESS

Focus on:

• Cooling method efficiency

• System scalability

• Grid certification

• After-sales technical support

A well-engineered system can significantly improve energy efficiency and reduce maintenance cost.
