3.72MWh 1331.2V Containerized Commercial Battery Energy Storage System With Liquid Cooling

3.72MWh 1331.2V Commercial Battery Energy Storage System with Liquid Cooling

This containerized commercial battery energy storage system provides approximately 3.72MWh of nominal LiFePO4 energy on a 1331.2V high-voltage DC platform. It is designed for large commercial, industrial and solar-plus-storage projects requiring multi-megawatt-hour battery capacity within a standardized container footprint.

The system uses 3.2V, 280Ah lithium iron phosphate cells arranged into ten 1P416S battery clusters. A general control cabinet integrates DC combining, power distribution, communication and battery-system control functions.

Multi-MWh Storage for Commercial Energy Projects

The 3.72MWh nominal capacity can be considered for industrial energy management, renewable-energy shifting and projects that need a substantial stored-energy reserve. Final system sizing should be based on the site load profile, required charge and discharge power, operating schedule and available charging source.

Battery energy and PCS power are separate project parameters. The battery capacity determines the stored-energy reserve, while the separately configured PCS determines AC charge and discharge power. The supplied specification does not state a PCS rating, transformer configuration or AC connection voltage.

1331.2V High-Voltage DC Platform

The commercial energy storage system operates at a nominal voltage of 1331.2Vdc, with a stated operating range of 1164.8–1497.6Vdc. This places the battery within a 1500V-class DC architecture for compatible commercial power-conversion equipment.

The listed charge and discharge rate is 0.8C, and the stated discharge depth is 90% DoD. The external PCS, DC cables, protection devices and isolation equipment must be selected according to the full battery-voltage range and required operating current.

The product sheet lists more than 8,500 cycles at 80% DoD. Actual battery performance depends on temperature management, operating rate, depth of discharge and project control strategy.

Liquid Cooling and Thermal Runaway Management

Liquid cooling technology is used to manage battery temperature across the container. Consistent thermal conditions are important in a multi-cluster battery system because temperature differences can affect available power, cell balance and long-term battery performance.

The listed thermal runaway management measures include aerosol extinguishing or PFH together with water-immersion response. The product description also identifies battery-level detection, smoke management, combustible-gas detection and pressure-release functions.

Final fire-protection design, site spacing, emergency access and local compliance requirements should be reviewed according to the installation country and project conditions.

20-Foot Container Deployment

The container measures 6058 × 2438 × 2896mm and has an approximate total weight of 40 tonnes. Transportation planning should consider lifting equipment, road access, foundation loading and the final equipment position.

The IP55 enclosure is suitable for protected commercial and industrial installations when cable entries, doors and external connections are correctly completed. The stated operating temperature is -20°C to 55°C, with operation up to 3000m and derating required above that altitude.

Containerized Commercial BESS FAQ

Why is the system described as 3.72MWh when the product class is 4MWh?

The 4MWh designation represents the product capacity class. The listed cell and cluster configuration provides approximately 3.72MWh of nominal battery energy.

Does the container include the PCS and transformer?

The supplied data defines the battery container and DC control functions but does not provide PCS power or transformer specifications. Their supply scope should be confirmed per project.

What information is required to select the PCS power?

Provide the required charge and discharge power, site load curve, operating schedule, grid standard and project control objective.

Can the commercial energy storage system be installed outdoors?

The container is rated IP55, but the foundation, cable entries, drainage, clearances and site protection must be engineered for the installation environment.

What should be prepared before container delivery?

Confirm the foundation, lifting plan, access route, cable interface, communication method, PCS location and required maintenance clearances.
