A battery cabinet is the DC energy storage part of the BESS. In a full energy storage project, the cabinet is normally connected with PCS, EMS, fire protection, HVAC or thermal control, AC distribution, and the site control system.
Standalone Use & Parallel Integration
This 100kWh cabinet can be used in two main ways.
Standalone Use
In standalone use, one 100kWh cabinet works as an independent battery energy storage unit. This is suitable for small C&I projects, backup power systems, solar storage sites, and equipment-level energy storage.
A standalone 100kWh battery cabinet is a good choice when the project needs simple installation, clear capacity, and easy maintenance.
Parallel Integration
For larger projects, multiple 100kWh cabinets can be connected in parallel. For example, 5 cabinets can form a 500kWh battery energy storage system, and 10 cabinets can form a 1MWh battery storage system.
Parallel battery cabinets help project teams scale capacity without redesigning the full battery system from zero.
For EPCs and system integrators, this makes project planning easier. For buyers, it makes future expansion more flexible.
Battery Cabinet Structure
The battery cabinet is designed for safe installation, easy wiring, and convenient maintenance.
The cabinet uses a rack-mounted battery module layout. Battery modules and the high-voltage box are arranged inside the cabinet, with high-voltage and communication connections placed at the front for easier service access.
The structure is designed to support mechanical strength, electrical safety, thermal management, and maintenance needs.
Key structure points include:
| Structure Area | Purpose |
| Battery Module Rack | Holds 8 battery modules in a fixed cabinet layout |
| High-Voltage Box Area | Manages HV output, protection, and switching |
| Front Wiring Access | Makes installation and inspection easier |
| Internal Cable Routing | Separates high-voltage and low-voltage circuits |
| Cabinet Base | Supports fixed installation on the project site |
| Lifting Rings | Supports lifting and cabinet movement during installation |
| Ventilation Path | Helps heat exchange inside the cabinet |
| Safety Labels | Supports safer service and maintenance work |
–
A good battery cabinet design reduces installation risk and makes maintenance faster.
Clear 100kWh Building Block
Engineers can use each cabinet as a clear 100kWh DC battery unit. This makes capacity planning easier.
Easier System Scaling
Project teams can scale from 100kWh to hundreds of kWh or MWh by adding more cabinets in parallel.
Lower Integration Workload
The cabinet already includes battery modules, BMS, high-voltage box, and internal wiring. This helps reduce project integration time.
Better Safety Management
The BMS monitors voltage, current, temperature, SOC, SOH, and protection status. This gives engineers more control over system safety.
Strong Fit for C&I Projects
The 100kWh size is practical for factories, buildings, farms, EV charging stations, and microgrid projects.
Custom Battery Support
Bonnen Battery can adjust battery voltage, capacity, cabinet design, communication, connector type, cable design, and system matching based on project needs.
Better Procurement Clarity
Project buyers can source a complete battery cabinet instead of buying loose cells, modules, BMS, and cabinet parts from different suppliers.
Manufacturer-Level Technical Support
Bonnen Battery supports battery design review, technical documents, production, testing, and project communication before delivery.
The 100kWh Commercial Battery Storage Cabinet is suitable for many C&I energy storage projects.
