108kWh High-Voltage Stacked Battery System
The Avepower 108kWh high-voltage battery system combines six 18kWh LiFePO4 battery modules with a dedicated high-voltage control unit. Designed for small commercial, hospitality and high-consumption energy projects, it delivers a 345.6V nominal platform, intelligent battery management and flexible inverter communication in a compact stacked configuration.
Designed for Installers, Distributors and Project Partners
Avepower provides a project-oriented high-voltage battery platform for solar installers, energy storage distributors, project developers and OEM partners. The modular structure, communication options and installer-accessible monitoring functions help simplify system selection, project configuration, commissioning and long-term service.
Six 18kWh Modules in One Integrated Battery Cluster
The system consists of six 57.6V 314Ah battery modules connected in series and managed by a dedicated high-voltage control unit. Each module provides 18kWh of nominal energy, allowing the complete cluster to reach 108kWh while maintaining a clearly structured and serviceable modular architecture.
345.6V High-Voltage Platform for Efficient System Integration
A 345.6V nominal DC platform helps reduce current requirements compared with lower-voltage battery systems at similar power levels. The system supports a recommended charge and discharge current of 50A and a maximum continuous current of up to 150A, providing flexibility for different operating strategies and project requirements.
Multi-Level Battery Management and Protection
The integrated battery management architecture monitors cell voltage, temperature, current, SOC and system operating status. Built-in protection functions cover overcharge, over-discharge, overcurrent, high temperature and low temperature, while the high-voltage control unit also integrates a circuit breaker and fuse for additional electrical protection.
Adaptive Charge and Discharge Control
The BMS adjusts allowable charging and discharging current according to cell temperature and battery SOC. Charging is disabled outside the specified 0°C to 55°C temperature range, while discharging is disabled at or below -20°C and at or above 60°C, helping protect the battery under unsuitable operating conditions.
Forced-Air Cooling for More Consistent Operation
The battery modules use temperature-controlled forced-air cooling to improve temperature consistency during operation. Fan speed can be managed through PWM control, with the fans automatically activated when the highest cell temperature exceeds 35°C and switched off when it falls below 32°C.
4.3-Inch Touchscreen for On-Site System Monitoring
The high-voltage control unit includes a 4.3-inch touchscreen that gives installers and operators access to total voltage, individual cell voltage, current, remaining capacity, SOC, alarm status and protection information. Multi-level permissions also support language selection and communication protocol configuration.
CAN and RS485 Communication for System Integration
CAN and RS485 communication interfaces enable the battery system to exchange operating data with compatible inverters, PCS equipment and energy management systems. Avepower can support protocol matching for different project platforms, helping installers reduce integration time and improve commissioning efficiency.
Structured Connections for Professional Installation
Quick-connect high-voltage terminals, dedicated communication interfaces and clearly defined module connections support a structured installation process. The battery modules are connected in series, linked to the high-voltage control unit and then connected to the inverter or PCS through dedicated power and communication cables.
Designed for Controlled Indoor Installation Environments
With an IP20 enclosure rating, the battery system is intended for dry indoor or otherwise protected installation areas. The installation location should provide adequate ventilation, no condensation, sufficient service access and protection from water, direct sunlight, excessive heat and combustible materials.
Designed for Small Commercial and High-Consumption Sites
The 108kWh battery cluster is suitable for projects that need more storage capacity than a typical residential battery but do not require a large containerized energy storage system. It can be integrated into solar self-consumption, backup power and energy management projects in suitable indoor environments.

FAQs
Find quick answers to the most frequently asked questions below and discover how it can transform your energy use.
The standard system consists of six 18kWh LiFePO4 battery modules and one high-voltage control unit. Required power cables, communication cables and installation accessories should be confirmed according to the project configuration.
The specification provides reference parameters for a 50kW-class inverter. However, the final inverter or PCS selection must be based on voltage range, maximum current, communication protocol, application and local system requirements.
No battery should be assumed to work with every inverter. Avepower supports CAN and RS485 communication and can assist with protocol matching, but the exact inverter brand, model and firmware version must be checked before ordering.
The standard enclosure is rated IP20 and is intended for dry indoor or protected installation environments. Outdoor installation requires a suitable external enclosure or a separately developed outdoor solution.
An optional Wi-Fi module can provide app-based remote monitoring. Wi-Fi hardware, app functions and project communication requirements should be confirmed when placing the order.
Yes. Avepower can support branding, appearance, communication protocols, system configuration, connectors, packaging, documentation and other OEM or ODM requirements based on project feasibility.
