GSL 5MWh Battery Energy Storage System – China Liquid Cooling BESS Manufacturer

1. What is a 5MWh Battery Energy Storage System?

A 5 MWh battery energy storage system is a large-scale solution designed to store 5 megawatt-hours of electrical energy.
Capacity meaning: It can deliver 5MW for 1 hour, or lower power output for a longer duration.
Technology: Most modern systems, like GSLs, use LiFePO4 lithium batteries with advanced BMS for safety and efficiency.
Applications: From grid balancing to renewable energy integration, these systems are essential in the global energy transition.

2. Where Can a 5MWh Battery Be Used?

A 5MWh battery is typically deployed in:

Utility-Scale Renewable Energy Projects – Store excess solar/wind power for later use.
Commercial & Industrial (C&I) Peak Shaving – Reduce peak demand charges by using stored energy during high-tariff periods.
Microgrids & Off-grid Communities – Provide stable electricity in remote areas.
Data Centers & Telecom – Ensure uninterrupted power for critical infrastructure.
EV Charging Stations – Store cheap off-peak power to fast-charge EVs during peak hours.

3. 5 MWh Battery Cost

The 5 mWh battery cost depends on battery chemistry, cooling system, container design, and installation requirements.
China manufacturers like GSL Energy typically offer competitive pricing thanks to vertical integration and factory-direct supply.
Reference range: USD 1.5M – 2.5M for a turnkey 5MWh lithium battery energy storage system (price may vary with inverter, EMS, site work).
Liquid-cooled designs may cost slightly more but offer higher energy density, longer lifespan, and better thermal stability.

5. How to Achieve 5MWh with Liquid-Cooled Battery Cabinets

To build a 5 MWh battery energy storage system using liquid cooling technology:
Select high-voltage battery racks – Each rack (e.g., 215–280kWh) is installed inside a liquid-cooled container.
Configure parallel connections – Multiple containers are paralleled to reach a total 5MWh capacity.
Integrate PCS & EMS – Power conversion systems regulate charging/discharging; energy management optimizes performance.
Thermal management – Liquid cooling maintains battery temperature at 20–30°C, increasing lifespan and performance.
