Reliable, High-Density Energy Storage Built
For EPC contractors, project developers, and energy investors, choosing the right 5MWh energy storage system is not just about capacity-it is about long-term reliability, lifecycle cost, and system stability. This liquid-cooled battery container is engineered to meet the demands of utility-scale and commercial & industrial (C&I) applications, where performance consistency directly impacts project returns.
Designed with advanced LFP technology and a fully integrated thermal management system, this solution delivers high energy density within a standard 20-ft container, while maintaining operational stability across a wide range of environmental conditions. Whether deployed in solar farms, microgrids, or peak shaving applications, it provides a dependable foundation for modern energy infrastructure.
Why Liquid Cooling Makes the Difference
Temperature control remains one of the most critical factors affecting battery performance and degradation. Unlike conventional air-cooled systems, this liquid cooled battery container combines liquid cooling with forced air circulation to maintain a cell temperature difference of ≤3°C.
This level of thermal consistency translates into more stable voltage output, reduced energy loss, and significantly improved battery lifespan. For large-scale projects, this means lower operational risk and a more predictable return on investment-key considerations when evaluating a utility scale battery storage solution.
At the same time, the system integrates a variable-frequency compressor that adapts to real-time conditions, reducing auxiliary power consumption and further optimizing system efficiency over the project lifecycle.

Engineered for Long-Term Performance
This system is not designed as a standalone product-it is built as a project-ready energy storage solution that aligns with real EPC requirements.
With a total system capacity of 5.015MWh, it enables efficient land use and simplifies large-scale deployment. The use of LFP 314Ah cells ensures enhanced safety and chemical stability, while a cycle life of ≥8000 cycles supports long-term project viability.
Noise reduction is another practical advantage. By minimizing fan usage, the system operates at a lower noise level compared to traditional air-cooled alternatives, making it suitable for installations near commercial or urban environments.
Safety is integrated at every level. The container includes a combined aerosol and water spray fire suppression system, along with an IP55-rated enclosure and optional C5 anti-corrosion protection, ensuring reliable operation in harsh climates.
FAQ
Q: What battery technology is used, and why is it reliable?
A: We use LFP (Lithium Iron Phosphate) 314Ah cells, which are widely recognized for their high thermal stability, long cycle life, and enhanced safety compared to other lithium chemistries. This makes them ideal for utility-scale battery storage and long-term projects.
Q: What is the expected cycle life and project lifespan?
A: The battery supports ≥8000 cycles, which typically translates to 10–15 years of operation, depending on usage patterns. This ensures strong long-term returns for energy storage investments.
Q: Can the system operate in extreme climates?
A: Yes. The system is designed to operate in temperatures from -25°C to 55°C, with derating above 45°C. It also supports 0–95% humidity (non-condensing) and altitudes up to 3000 meters, making it suitable for diverse project locations.
Q: What level of protection does the container provide?
A: The container is rated IP55, offering strong protection against dust and water ingress. It also features C4 anti-corrosion coating (C5 optional) for harsh environments such as coastal or industrial areas.
Q: What kind of maintenance is required?
A: Thanks to the liquid cooling design and stable LFP chemistry, the system requires minimal maintenance. Routine checks include cooling system inspection, electrical connections, and software monitoring via BMS/EMS.
