Reliable 8kWh Battery for Home Solar Storage
The Avepower 25V 314Ah LiFePO4 battery provides 8kWh of nominal storage capacity in a compact floor standing cabinet. It is suitable for residential solar systems, backup power, off-grid homes, villas, cabins, telecom backup, small workshops and installer-led solar battery projects.
Compared with traditional lead-acid batteries, LiFePO4 chemistry offers higher usable energy, lower maintenance, better thermal stability and a longer cycle-life potential under proper operating conditions.
8,000+ Cycles for Long-Term Reliability
With a long service life of over 8,000 charge and discharge cycles, the 8kwh battery delivers reliable performance for years of daily use. Its space-saving upright design reduces floor footprint while allowing easy installation and maintenance.
200A Smart BMS for Safer Charging and Discharging
This 8kwh battery uses a 16S 200A software protection board. The smart BMS helps monitor and protect the battery during charging, discharging and standby operation. The 200A BMS allows the battery to deliver up to 5.12kW output at battery level under proper system conditions. Actual usable power depends on inverter capacity, cable design, BMS settings, battery temperature and installation environment.
3.2-Inch Button Blue Screen for Local Battery Status
The built-in 3.2-inch button blue screen allows installers and users to check battery information directly on the unit. This is helpful during installation, commissioning, daily inspection and maintenance.
The display improves local visibility without requiring the cabinet to be opened. It is especially useful for installers who need quick battery status checks on site.
Bluetooth and WiFi Monitoring for Easier System Management
With Bluetooth and WiFi support, users and installers can monitor battery status more conveniently. Depending on the matched system and monitoring platform, battery data may include state of charge, voltage, current, operating temperature, charge/discharge status and alarm information.
CAN, RS485 and RS232 Communication for Inverter Integration
The 8kwh battery supports CAN, RS485 and RS232 communication, making it easier to integrate with compatible hybrid inverters, off-grid inverters and energy management systems. Before bulk ordering or project installation, Avepower can help confirm communication protocol matching with your target inverter model.
Up to 16 Units in Parallel for Expandable Storage
This 8kwh battery supports up to 16 units in parallel. One unit provides approximately 8kWh of nominal energy. This makes the battery suitable not only for individual home backup systems but also for larger villas, small commercial storage rooms, telecom backup, off-grid buildings and solar-plus-storage projects requiring scalable capacity.
Floor Standing Cabinet with Adjustable Support Feet
Unlike wall-mounted batteries, this 8kwh battery uses a floor standing cabinet structure. The compact size helps installers place it in garages, utility rooms, equipment rooms, storage areas and other protected indoor locations.
The cabinet includes adjustable support feet. The body dimension is 530 × 263 × 750mm excluding support feet, and up to 530 × 263 × 800mm when the feet are adjusted to the highest position. This design helps improve placement stability on different installation surfaces.
The battery also includes a 200A 1P air switch, 200A fence-style through terminal posts and a circular light soft switch, helping installers complete wiring and system operation more efficiently.
Wide Operating Temperature Range for Daily Energy Storage
The 8kwh battery is designed for residential and light commercial energy storage environments. It supports charging from 0°C to 55°C and discharging from -20°C to 60°C. Avoid direct sunlight, moisture, high heat, corrosive gas and improper stacking during storage.
OEM ODM Custom Options
Avepower supports customization for energy storage distributors, wholesalers, installers, EPCs and OEM / ODM partners. Custom options may include exterior design, logo, label, packaging, communication settings, monitoring configuration, capacity planning and project-based battery system matching.
Ideal Applications and Use Cases
It is an ideal choice for small villas and apartments where space is limited, thanks to its compact and flexible design. The system also works well with hybrid inverter setups and retrofit upgrades, making it easy to integrate into existing solar installations. In addition, it is well suited for distributor private-label programs and project supply, offering scalability and customization to meet different market needs.
