Built for Solar Storage and Backup Power Projects
Avepower 20kWh battery system is designed for residential, off-grid, farm, telecom, and small commercial storage. Its integrated cabinet design helps simplify wiring, installation, inspection, and system management.
20kWh-Class Cabinet System with Four Battery Modules
This 20kWh battery cabinet uses four 100Ah 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.
100A BMS for Safer Battery Operation
Each battery module is equipped with a 100A 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.
Bluetooth and WiFi Monitoring for Easier System Management
The 20kWh battery supports Bluetooth and Wi-Fi monitoring for easier commissioning, daily checks, and maintenance. Installers can reduce on-site inspection time and simplify after-sales support.
3.2-Inch Blue Button Screen for Local Monitoring
Each module features a 3.2-inch blue button screen for quick local checks of battery status, voltage, current, alarms, and operating data, making installation and maintenance easier for installers.
CC-CV Charging with up to 150A Max Charge Current Per Module
Each 51.2V 100Ah 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 module supports 140A standard discharge and up to 200A maximum discharge, while the cabinet includes copper busbars and a 600A inverter cable. The system can support inverter applications below 30kW when properly configured.
RS485 RS232 CAN Communication for Inverter Integration
The 20kWh battery supports RS485, RS232, and CAN communication for inverter integration and monitoring, with protocol matching and configuration support based on the inverter brand and project requirements.
Expandable Battery System Design
This 27U cabinet comes with four 51.2V 100Ah 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 20kWh battery cabinet features two 5 × 25 × 1000mm copper busbars and a 600A inverter output cable (75mm² × 1.5m) for efficient system-level current collection and inverter connection.
Practical Hardware Design for Installation and Maintenance
Each module features a 200A terminal, 200A air switch, 6A soft switch, and maintenance port, making installation, inspection, and servicing easier for rack cabinet energy storage projects.
Reliable Operation Across Common Storage Environments
Each battery module supports 0°C–55°C charging and -20°C–60°C discharge, suitable for indoor and protected energy storage environments. Recommended storage is 0°C–45°C for 1 month, 0°C–35°C for 3 months, and 0°C–25°C for 6 months.
OEM ODM Battery Cabinet Customization for Project Customers
Avepower supports OEM/ODM customization for distributors, installers, wholesalers, and project developers, including cabinet design, branding, capacity, communication protocols, cable layout, packaging, 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.
