Product Features
The 418kWh liquid-cooled battery cabinet is designed for medium- to large-scale storage sites, including commercial parks, renewable energy integration, standalone storage plants, and regional microgrids.
It fills the gap between small air-cooled cabinets and large containerized systems—offering nearly container-level energy density while keeping the flexibility of modular installation. Each cabinet features independent liquid cooling and a modular structure, enabling seamless side-by-side expansion and multi-cabinet parallel operation.
The system can integrate with external power conversion and boost units to build high-voltage grid-connected storage ranging from 1MWh up to several tens of MWh, improving project ROI, safety, and deployment efficiency.
Ultra-High Energy Density
Single cabinet holds 418kWh in just 1.7m², delivering superior energy per square meter compared to air-cooled solutions. Saves land and civil construction costs for commercial and industrial projects.
Precise Liquid Cooling & Temperature Control
PACK-level liquid cooling channels keep cell temperature differences under 3°C, improving battery consistency, reducing cycle degradation, and extending service life.
Advanced Safety & Fire Protection
Equipped with PACK-level fire warning and automatic perfluorohexanone (FPH) suppression. Quickly stops thermal runaway and prevents heat propagation.
Flexible Modular Expansion
Supports side-by-side cabinet placement and multi-unit parallel operation. Compatible with different grid access methods and phased construction planning.
Efficient System Integration
As the core battery unit, it works seamlessly with external PCS and boost converters for high-voltage direct grid connection, simplifying system architecture.

What projects is the 418kWh liquid-cooled BESS suitable for?
The 418kWh liquid-cooled battery cabinet is ideal for medium- to large-scale storage projects, including commercial and industrial parks, renewable energy integration, standalone storage plants, and regional microgrids. Its high energy density and modular design make it flexible for phased deployment and capacity expansion.
Does this system have built-in liquid cooling and temperature control?
Yes. Each cabinet features an independent liquid cooling system. PACK-level cooling channels keep cell temperature differences under 3°C, improving battery consistency, reducing degradation, and extending service life. This precise thermal management is key for long-term reliability in commercial and industrial applications.
How safe is the 418kWh liquid-cooled battery cabinet?
The cabinet includes PACK-level fire warning sensors and an automatic perfluorohexanone (FPH) suppression system. This setup quickly prevents thermal runaway and stops heat propagation, ensuring safe operation even under high-density energy storage conditions. The robust IP55 enclosure further protects against dust and water ingress.
Can the system be expanded or connected with other cabinets?
Yes. The modular design supports side-by-side placement and multi-unit parallel operation. You can scale storage from a single 418kWh cabinet up to tens of MWh, making it suitable for phased projects or projects requiring flexible capacity planning.
Can this cabinet integrate with external PCS or grid converters?
Absolutely. The 418kWh liquid-cooled BESS can work seamlessly with external power conversion systems (PCS) and boost converters for high-voltage direct grid connection. This simplifies the system architecture while enabling large-scale, high-voltage commercial and industrial energy storage deployments.
How does the system improve ROI and operational efficiency?
With high energy density and precise liquid cooling, the cabinet maximizes usable energy per square meter while extending battery life. Modular design reduces civil and installation costs. By integrating with solar, wind, or other distributed energy, it supports peak shaving, load balancing, and grid services, increasing project ROI.
Commercial and Industrial Battery Energy Storage Systems (C&I BESS) are designed to help businesses manage energy more efficiently and maintain stable power supply. These systems store electricity and discharge it during peak demand or grid instability, providing fast, clean, and reliable energy support for daily operations.
Battery energy storage enables peak shaving and load shifting, helping businesses reduce electricity costs and demand charges. It also delivers reliable backup power during outages, protecting critical equipment and minimizing downtime. When integrated with solar or other renewable sources, C&I BESS improves energy utilization and reduces dependence on diesel generators.
Due to higher power demand and system requirements, commercial and industrial energy storage is typically deployed in factories, logistics centers, EV charging hubs, commercial buildings, data centers, and solar-plus-storage projects where stable, scalable, and high-availability power is essential.
