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 20.48kWh ultra-thin wall-mounted LiFePO4 energy storage battery is designed
for residential solar energy storage, home emergency backup power, and outdoor off-grid
electricity use. It is also suitable for villas, farms, small shops, small factories,
and other small-scale energy storage applications.
Each unit provides 20.48kWh of energy storage capacity and measures 1090 × 654 × 181mm.
Compared with ordinary wall-mounted energy storage batteries, its slim body makes it
much easier to install and helps save valuable indoor or equipment-room space.
The battery supports multi-unit parallel connection. Up to 20 units can be connected
in parallel, expanding the total system capacity to 409.6kWh. This allows users to scale
the system flexibly according to actual power demand, whether for daily home storage,
outdoor off-grid power, or long-duration backup power for shops and small commercial sites.
Equipped with BYD LiFePO4 battery cells, the system delivers stable safety performance,
reliable power output, long service life, and excellent fire and explosion resistance.
It is a practical energy storage choice for home solar storage, whole-house power backup,
off-grid use, and small commercial energy systems.
- 20.48kWh large capacity for home use, solar self-consumption, and backup power.
- Supports up to 20 units in parallel, expanding total capacity to 409.6kWh.
- Uses safe and reliable LiFePO4 battery cells.
- 8000-cycle design for high safety, high stability, and long service life.
- Suitable for solar energy storage, peak-valley power management, and outage backup.
- Supports off-grid power supply and helps improve renewable energy utilization.
- Stable operation for long-term residential and commercial energy storage.
- Integrated ultra-thin appearance with a modern, clean, and space-saving design.
- More compact and lighter in layout than traditional cabinet or stackable batteries.
