Built for Solar Storage and Backup Power Projects
The Avepower 20kWh battery system is suitable for projects that need larger battery capacity, organized cabinet installation and practical inverter connection. It can store solar energy during the day and supply power during the evening, peak tariff periods or grid outages.
This system is especially useful for residential energy storage rooms, villas, off-grid buildings, small commercial backup systems, telecom equipment rooms, farms, workshops and installer-led solar battery projects. Compared with installing several separate battery modules on site, the cabinet solution helps keep wiring cleaner and makes the system easier to inspect, manage and expand.
20kWh-Class Cabinet System with Four Battery Modules
This 20kWh battery cabinet uses four 280Ah LiFePO4 battery modules installed inside a C0411 27U universal cabinet. Each module provides 5kWh-class energy storage capacity, while the complete cabinet provides a 20kWh-class battery system for longer backup time and higher daily solar self-consumption.
Configurable Battery Cabinet for Flexible Project Needs
This rack mount battery cabinet can be customized with either 4 × 5kWh or 4 × 15kWh battery modules, giving installers, distributors and project developers more flexibility for different energy storage applications. The cabinet design supports both low-voltage and high-voltage customization, making it easier to match different inverter systems, project capacities and installation requirements.
200A BMS for Safer Battery Operation
Each battery module is equipped with a 200A protection board to support safer charging, discharging and system operation. The BMS helps protect the battery against over-charge, over-discharge, over-current and temperature-related risks.
280Ah LiFePO4 Cells in a 16S1P Pack
Each battery module uses 280Ah LiFePO4 cells with a 16S1P pack structure. LiFePO4 chemistry is widely used in solar energy storage systems because it is suitable for deep-cycle charging and discharging, long-term backup power and daily solar self-consumption applications.
The 280Ah cell format gives each battery module a strong capacity foundation while keeping the system compatible with 51.2V low-voltage inverter platforms. For installers and system integrators, this helps simplify project design when building cabinet-style solar storage systems.
Bluetooth and WiFi Monitoring for Easier System Management
The 20kWh battery system supports Bluetooth and WiFi monitoring, making it easier for installers and users to check battery status during commissioning, daily operation and maintenance. Key battery information can be viewed through the built-in screen or monitoring interface depending on the final system configuration.
This helps users check operating status more conveniently without opening the cabinet frequently. For installers, Bluetooth and WiFi functions can also reduce on-site inspection time and make after-sales support more efficient.
3.2-Inch Blue Button Screen for Local Monitoring
Each battery module includes a 3.2-inch blue button screen for local battery monitoring. During installation, commissioning and maintenance, the screen allows technicians to check basic battery information directly from the front panel.
The screen can help display practical information such as battery status, voltage, current, alarm status and operating data depending on the final BMS configuration. This makes the system more convenient for equipment rooms, residential energy storage rooms, telecom cabinets and small commercial battery projects.
CC-CV Charging with up to 150A Max Charge Current Per Module
Each 51.2V 280Ah battery module uses CC-CV charging mode and supports a charging voltage of 58.4V. Under 0°C to 10°C conditions, the standard charge current is 56A. Under 10°C to 45°C conditions, the maximum charge current can reach 150A when the inverter, charger, cable size and system protection settings are properly configured.
200A Max Discharge Current Per Module
Each battery module supports 140A standard discharge current and up to 200A maximum discharge current. This makes the system suitable for solar storage projects that need stronger output capability than smaller single-battery backup systems.
At cabinet level, the system includes copper busbars and a 600A inverter output cable. The final system output should be matched with the inverter rating, protection devices, cable design and installation environment. According to the provided configuration, the cabinet can be matched with inverter systems below 30kW when the full system design is properly configured.
RS485 RS232 CAN Communication for Inverter Integration
The 20kWh battery modules support RS485, RS232 and CAN communication, helping the battery system connect with compatible inverter systems and monitoring equipment. These communication options allow the inverter to read battery data, manage charging and discharging logic and improve system coordination. Avepower can support communication configuration according to inverter brand, protocol requirements and project application.
Expandable Battery System Design
This 27U cabinet comes with four 51.2V 280Ah 5kWh battery modules as a standard 20kWh-class configuration. The module design also supports parallel expansion, with up to 16 battery modules supported depending on system configuration.
Copper Busbar and 600A Inverter Output Cable
The cabinet is equipped with two copper busbars, each with T5.0 mm × W25 mm × L1000 mm dimensions. The copper busbar configuration supports system-level current collection within the designed over-current range.
The system also includes a 600A inverter output cable, using 75mm² cable with a length of 1.5 meters. This helps simplify connection between the battery cabinet and inverter. For final installation, cable routing, protection devices and inverter matching should be confirmed by qualified installers according to local electrical requirements.
Practical Hardware Design for Installation and Maintenance
Each battery module is designed with a 200A wall-mounted terminal, 200A air switch, 6A circular soft switch, maintenance port and black housing. These hardware details make the system more practical for installation, inspection and service work.
The 200A terminal supports high-current battery connection, while the air switch and maintenance port help simplify system inspection and maintenance. For rack cabinet projects, these front-panel hardware features make the battery easier to operate and manage during real project use.
Reliable Operation Across Common Storage Environments
Each battery module supports charging from 0°C to 55°C and discharging from -20°C to 60°C. This operating range makes the system suitable for many indoor or protected energy storage environments, including garages, utility rooms, telecom rooms, equipment rooms and enclosed battery cabinets.
For storage before installation, the battery should be kept in a clean, dry and controlled environment. The recommended storage temperature is 0°C to 45°C for one month, 0°C to 35°C for three months and 0°C to 25°C for six months.
OEM ODM Battery Cabinet Customization for Project Customers
Avepower supports OEM and ODM customization for distributors, installers, wholesalers and project developers. The rack cabinet battery system can be adjusted according to branding requirements, inverter communication protocols, cabinet layout, capacity configuration and project documentation needs.
Customization options can include cabinet appearance, label design, logo, packaging, communication protocol, front-panel layout, capacity configuration, cable design and project-specific technical support
Suitable Applications
The Avepower 20kWh battery system is suitable for projects that need larger storage capacity, clean cabinet installation, inverter communication and future expansion. It can be used as a solar storage battery cabinet, backup power battery system or low-voltage battery storage solution for different residential and small commercial scenarios.
