ENR-257-200k-400-A All-in-One C&I Energy Storage System
The ENR-257-200k-400-A is an integrated 257kWh commercial and industrial (C&I) battery energy storage system designed for businesses seeking efficient energy management, flexible power configuration, and simplified system deployment. Combining a lithium iron phosphate (LFP) battery system, power conversion system (PCS), battery management system (BMS), energy management system (EMS), and power distribution components in one cabinet, it reduces external wiring requirements and simplifies system integration.
All-in-One Integrated Architecture
The integrated design minimizes inter-device wiring and reduces installation complexity, communication integration effort, and equipment compatibility risks. The coordinated system architecture helps streamline commissioning, operation, and maintenance for commercial and industrial energy storage projects.
Flexible Parallel Expansion
The system supports multi-unit parallel operation, with one EMS designed to manage up to five parallel units according to the proposed configuration. This modular approach allows system capacity and power to be scaled according to project requirements. Grid-forming applications can be supported when the selected PCS configuration and system controls provide the required functionality.
Plug-and-Play Deployment
The compact cabinet integrates key energy storage components into a unified system, helping reduce on-site assembly and wiring work. Its integrated architecture supports convenient transportation, installation, commissioning, and routine maintenance, making it suitable for a wide range of commercial and industrial sites.
High-Power Configuration for Solar Integration
With a maximum PV input power of 240kW and a maximum AC power rating of 200kW, the ENR-257-200k-400-A is designed for applications requiring substantial solar integration and flexible power delivery. Its power-oriented configuration can help businesses manage higher power demands, improve solar energy utilization, and optimize the balance between battery capacity and power conversion capability.
Reliable LFP Battery Technology
The system uses 314Ah lithium iron phosphate (LFP) cells, providing 257kWh of nominal battery capacity. The battery configuration comprises 16 packs, each rated at 16.077kWh. With 128 temperature detection points and a specified cycle life of 8,000 cycles under the stated test conditions, the battery system is designed to support long-term commercial energy storage applications.
Flexible Commercial Energy Management
The integrated architecture is suitable for solar self-consumption, peak shaving, time-of-use energy management, and backup power applications when supported by the project configuration. It can be considered for factories, commercial buildings, industrial facilities, and distributed energy projects.
The ENR-257-200k-400-A provides a compact and scalable foundation for C&I energy storage, combining integrated system architecture, flexible expansion, and high-power solar integration in one cabinet.
Note: Actual operating modes, grid-forming capability, backup functionality, and parallel-unit limits depend on the final PCS, EMS, protection, and system configuration.
