The 2507kWh 1500V DC Battery Energy Storage System (BESS) is a containerized liquid-cooled energy storage solution designed for utility-scale and large-scale commercial and industrial applications. It can be deployed for grid-side energy storage, renewable energy integration, industrial and commercial energy management, and microgrid or backup power applications, subject to the requirements of the local power system and project design.
The system adopts a 1500V DC architecture, which enables higher system voltage and lower DC operating current compared with lower-voltage architectures at the same power level. This can help reduce DC-side conduction losses and optimize the design of cables, connectors, and other electrical components.
The BESS integrates LFP (Lithium Iron Phosphate) battery cells, a Battery Management System (BMS), liquid-cooled thermal management, fire protection, power distribution, and system monitoring within a prefabricated containerized platform. The integrated design is intended to simplify transportation, installation, commissioning, and subsequent system expansion.
With factory-level integration and pre-commissioning, the system can help reduce on-site installation work and support standardized deployment for large-scale energy storage projects.
The system uses high-capacity LFP battery cells and a cluster-based electrical architecture designed for stable operation under the specified operating conditions.

Note: Actual usable energy, efficiency, cycle life, operating temperature performance, and service life may vary depending on battery configuration, charge/discharge rate, ambient temperature, installation conditions, operating strategy, and other project-specific factors. Final performance should be verified against the applicable product datasheet and test reports.
The 1500V DC architecture allows the system to operate at a higher DC voltage and lower current for a given power output. Lower current can reduce resistive losses in the DC circuit and may allow more efficient sizing of cables and other electrical components.
For large-scale BESS projects, the higher-voltage architecture can also support a compact system configuration and help optimize balance-of-system costs. The actual cost advantage depends on project capacity, PCS selection, cable distance, installation requirements, and local electrical standards.
Compared with lower-voltage battery systems, a 1500V configuration is particularly suitable for projects where high energy capacity, system integration, and optimized electrical architecture are important considerations.
The BESS uses a liquid-cooled thermal management system to regulate battery temperature during charging and discharging.
Compared with conventional air cooling, liquid cooling can provide more direct and uniform heat transfer within a high-energy-density battery system. Proper temperature management helps maintain battery performance and can reduce temperature-related battery degradation when the system is operated within its specified conditions.
The system is designed to maintain a container internal temperature difference of ≤3°C under specified operating conditions, supporting more consistent thermal conditions across battery clusters.
The specified operating temperature range is -20°C to +50°C. Actual charging, discharging, and power availability at temperature extremes should be determined according to the manufacturer's operating specifications and project configuration.
Safety is addressed through multiple levels of monitoring and protection across the battery and system architecture.
The BESS incorporates functions including:
The BMS continuously monitors key battery operating parameters and can generate alarms or initiate protective actions when abnormal conditions are detected, depending on the severity of the fault and system configuration.
The fire protection system uses a clean-agent suppression solution, while the overall safety architecture is designed to provide multiple layers of protection rather than relying on a single safety function.
For project deployment, fire protection configuration and compliance should be verified against applicable local codes, standards, authority requirements, and project-specific risk assessments.
The system adopts an integrated prefabricated container design that combines the main battery clusters with supporting subsystems such as:
Factory integration and pre-commissioning can reduce the amount of assembly and commissioning required at the project site. This approach can help improve installation consistency and shorten project implementation time compared with systems requiring extensive field assembly.
The modular architecture also allows multiple BESS units to be combined to achieve larger project capacities, subject to the electrical design, PCS configuration, EMS architecture, and site requirements.
The BESS can be connected to a remote monitoring and energy management platform for centralized system supervision.
Depending on the selected configuration, monitoring functions may include:
Continuous monitoring helps operators identify abnormal operating conditions at an early stage and supports preventive maintenance.
The combination of long-cycle LFP battery technology, thermal management, automated protection, and remote monitoring is designed to reduce routine manual intervention and support long-term BESS operation.
The 2507kWh 1500V liquid-cooled BESS can be configured for a range of energy storage applications.
The system can support grid-side applications such as:
The exact services available depend on the grid operator, PCS configuration, EMS strategy, market structure, and applicable regulations.
When paired with photovoltaic or wind power generation, the BESS can store excess renewable electricity and release it when generation is lower or electricity demand is higher.
Potential benefits include:
The actual impact on renewable energy curtailment depends on the generation profile, grid conditions, storage capacity, dispatch strategy, and project operating rules.
For large industrial facilities, commercial buildings, and energy-intensive sites, the BESS can support:
Where electricity tariffs include demand charges or time-based pricing, an appropriately sized BESS may help reduce electricity costs by shifting energy consumption to more favorable periods. Actual savings depend on local electricity tariffs, load profiles, battery efficiency, operating strategy, and regulatory conditions.
The system can also be incorporated into microgrid and backup power architectures for applications such as:
When connected to a compatible PCS and microgrid control system, stored battery energy can be used to support designated loads during grid interruptions.
Backup performance depends on the load profile, available battery energy, PCS power rating, grid-forming/grid-following capabilities, and overall microgrid configuration.
The 2507kWh system combines high-voltage DC architecture, LFP battery technology, liquid cooling, layered safety protection, and containerized system integration into a single energy storage platform.
Its design is intended to address the practical requirements of large-scale energy storage projects, including:
For project developers, EPC contractors, utilities, and commercial energy users, the final BESS configuration should be selected according to energy capacity, power requirements, grid connection conditions, site environment, fire safety requirements, local regulations, and the intended operating strategy.
Successful BESS deployment requires more than battery capacity alone. System selection should consider the complete electrical and control architecture, including the battery system, PCS, EMS, transformer, switchgear, protection system, thermal management, fire protection, communications, and grid connection equipment.
Technical documentation such as product datasheets, battery test reports, certification documents, installation manuals, warranty conditions, and system performance data should be reviewed during project evaluation.
Our engineering team can support project-specific configuration and technical evaluation based on the required capacity, power rating, operating conditions, renewable energy source, grid requirements, and installation environment.
