PVBAT 20.48kWh Ultra-Thin Wall-Mounted LiFePO4 Battery | Solar Energy Storage
PVBAT 20.48kWh Ultra-Thin Wall-Mounted LiFePO4 Energy Storage Battery
The PVBAT BEAR-48G1 20.48kWh ultra-thin wall-mounted LiFePO4 energy storage battery is designed
for home solar energy storage, emergency backup power, and off-grid power applications. It is also
suitable for villas, farms, small shops, small factories, and other small-scale energy storage projects.
Each unit provides 20.48kWh rated energy and 400Ah rated capacity with a 51.2V rated voltage.
Its 1090x181x654mm ultra-thin body supports wall-mounted installation, helping save floor space
while keeping the system layout clean and modern.
BEAR-48G1 supports up to 16 batteries in parallel, allowing total system capacity to expand to
approximately 327.6kWh. This gives users flexible capacity planning for daily solar self-consumption,
outdoor off-grid power supply, and longer-duration backup power for homes and small commercial sites.
The battery uses LiFePO4 (LFP) chemistry with an 8000-cycle design at 80% depth of discharge.
It is built for stable long-term operation, reliable output, safer energy storage performance,
and practical use in residential and small commercial energy systems.
