A Complete DC Battery Cabinet for Commercial Energy Storage
The cabinet integrates the battery packs, high-voltage control unit, BMS, thermal management, fire protection and system monitoring components into one coordinated DC energy storage platform.
It must be connected to a compatible external PCS to convert the stored DC energy into AC power. The PCS, EMS, solar array and switchgear can then be configured according to the load profile and operating strategy of each project.
Six Battery Packs in One Integrated High-Voltage Cluster
The cabinet uses a 1P18S × 6 battery architecture to provide 108kWh of nominal energy at 345.6V. Six battery packs are connected into a high-voltage cluster and managed through a dedicated high-voltage control unit.
The modular internal arrangement separates the battery packs, control components and auxiliary equipment, making key components easier to inspect, replace and maintain.
Designed for 50kW-Class PCS Integration
The 345.6V high-voltage platform is designed for integration with commercial PCS equipment. The battery operates across a DC voltage range of 324V to 388.8V and supports rated 0.5P charge and discharge operation.
For system matching, the selected PCS should cover the complete battery voltage range, provide a maximum DC voltage rating of at least 400V, support at least 156A continuous DC current and communicate with the BMS through an approved CAN protocol.
314Ah LFP Cells for Long-Term Energy Storage
The system uses prismatic lithium iron phosphate cells selected for their thermal stability, long cycle performance and suitability for stationary energy storage applications.
Under the specified test conditions, the cabinet provides at least 8,000 cycles to 70% state of health at 0.5P and 25°C. A recommended depth of discharge of up to 95% helps projects make effective use of the installed storage capacity.
Air-Conditioned Thermal Management for Balanced Cell Temperatures
An industrial air-conditioning unit and dedicated air distribution duct provide controlled cooling, heating and ventilation throughout the cabinet. Airflow is distributed across the battery packs to reduce temperature differences between different positions inside the enclosure.
Under 0.5P charge and discharge conditions, cell temperature variation is controlled within 5°C and cell temperature rise within 10°C, supporting consistent battery performance and reducing localised thermal stress.
Adaptive Charge and Discharge Control Based on SOC and Temperature
The BMS continuously evaluates cell temperature, SOC, voltage, current and system status before calculating the permitted charge and discharge current. This allows the PCS to reduce output or stop operation when the battery approaches its operating limits.
Intelligent BMS Monitoring and Protection
The battery management system monitors the electrical, thermal and communication status of the complete battery cluster. It sends real-time operating data, alarm information, charge and discharge permissions and current limits to the PCS.
Multi-Layer Safety Protection from Detection to DC Isolation
The cabinet combines electrical protection, environmental sensing and emergency shutdown logic. Critical sensors are connected to the safety I/O module inside the high-voltage control unit, allowing the BMS to coordinate alarms, current restrictions and DC circuit isolation.
CAN, RS485 and TCP Communication for System Integration
CAN, RS485 and TCP interfaces support communication between the battery, PCS, thermal management system and other project equipment. The BMS can transmit SOC, SOH, voltage, current, temperature, alarms, operating permissions and real-time current limits.
Optional Bluetooth or Wi-Fi functions can support wireless commissioning, remote monitoring, device management and software updates, depending on the selected project configuration.
IP55 Cabinet for Suitable Outdoor and Industrial Installations
The IP55 enclosure provides protection against dust and water exposure for properly planned outdoor and industrial energy storage installations. Front and rear access doors, mechanical locks, dedicated cable entries and external status controls support practical installation and maintenance.
Designed for Commercial and High-Consumption Energy Sites
The 108kWh cabinet is suitable for projects that require more storage capacity than a typical residential battery but do not need a large containerised energy storage system.
It can be integrated into commercial solar self-consumption, peak shaving, time-of-use energy management, backup power and temporary emergency energy systems.

FAQs
Find quick answers to the most frequently asked questions below and discover how it can transform your energy use.
The technical specification uses a 50kW-class PCS as the reference configuration. The PCS should cover the complete 324–388.8V battery operating range, support the required DC current and use a compatible CAN communication protocol.
Multi-cabinet expansion can be supported through a coordinated high-voltage system architecture and multi-cluster CAN communication. The final number of cabinets depends on the PCS, EMS, DC bus and project design.
The first inspection is recommended within 30 days after installation, followed by routine inspection every 90 days. Additional inspection should be carried out whenever abnormal charging, discharging or alarm behaviour occurs.
The BMS supports several mainstream high-voltage CAN protocol formats, but compatibility must be confirmed by exact PCS brand, model, firmware and protocol version. Provide this information to Avepower before ordering.
Optional Bluetooth or Wi-Fi functions can support wireless commissioning, remote monitoring, device management and software updates, depending on the selected configuration.
Yes. Avepower can evaluate cabinet branding, appearance, communication protocols, monitoring functions, labels, packaging and technical documentation for OEM/ODM and project orders.
