1.28kWh 12.8V 100Ah LiFePO4 Lithium Battery With Solar Backup And Home Storage

1.28kWh 12.8V 100Ah LiFePO4 Battery with Solar Backup and Home Storage

This 1.28kWh LiFePO4 battery provides a balanced 12.8V, 100Ah energy-storage option for solar backup, wind power systems, UPS equipment and selected home energy applications.

Compared with the smaller 50Ah configuration, the 100Ah battery provides twice the nominal energy while remaining on the same 12V platform. It can be integrated with a compatible charge controller, inverter or DC load system.

Balanced Capacity for Solar and Backup Projects

The 1280Wh capacity can store energy generated during the day for lighting, communication equipment, monitoring devices and other selected loads. It also provides a practical battery size for small backup systems requiring more reserve than a compact UPS battery.

Battery runtime depends on the load schedule, inverter efficiency and required reserve. Buyers should calculate daily watt-hour consumption before selecting one or more batteries.

Compatible Charging from Different Energy Sources

The battery supports charging from a compatible solar controller, wind-energy controller or AC charger. The charging system must follow the 14.0–14.6V maximum charging-voltage range.

Its standard charging current is 20A, and the maximum charging current is 50A. The listed discharge current is 100A, allowing the battery to support higher DC demand than the 50Ah version when the complete system is correctly configured.

Indoor and Protected Energy Storage Placement

The iron battery case measures 340 × 185 × 220mm and weighs approximately 13.15kg. Installation planning should include secure positioning, ventilation and suitable cable access.

The IP55 enclosure provides resistance to dust and water jets, but the battery should still be installed where terminals and electrical connections remain protected.

Solar Storage Battery FAQ

Why choose the 100Ah version instead of the 50Ah battery?

It provides twice the nominal energy and supports a higher listed charging and discharging current.

Can solar and wind power both charge the battery?

Yes, when a compatible controller regulates the charging voltage and current according to the battery specification.

Can this battery provide home backup power?

It can support selected loads when connected to a compatible inverter, but capacity should be checked against the required backup period.

What is the listed monthly self-discharge rate?

The specification lists self-discharge of no more than 3.5% per month at 25°C.

What project information helps select cables and protection?

Provide the charger current, inverter power, expected discharge current, cable length and system layout.
