2.56kWh 25.6V 100Ah Wall Mounted LiFePO4 Battery for Solar Storage

Compact 25.6V Battery for Residential Solar Storage

This 2.56kWh wall mounted LiFePO4 battery combines a nominal voltage of 25.6V with a rated capacity of 100Ah. It is designed for compatible low-voltage solar inverters, off-grid energy systems and residential backup applications that require a compact indoor battery.

The battery provides up to 100A of continuous discharge current and supports up to 50A of continuous charging current. These documented limits help installers evaluate inverter demand, charging settings, battery cables and DC protection before completing the system design.

Its wall-mounted enclosure measures 460 × 410 × 139mm and has a listed net weight of 25kg. The slim structure can help keep the floor clear in utility rooms, equipment areas and other protected indoor installation locations.

Solar Battery Benefits for Installers and Distributors

Inverter Matching and Charging Settings

The connected inverter must support a nominal 25.6V battery system and operate within the listed battery voltage range of 20.0–29.2Vdc. The inverter charging profile should also support the specified 28.0V floating-charge voltage.

The charging-current setting should not exceed the battery’s 50A continuous limit. The final value may need to be lower depending on the inverter, cable size, ambient temperature and overall system configuration.

The inverter’s maximum battery current should be compared with the 100A continuous discharge rating. A higher inverter power label does not automatically mean the battery can supply the required DC current under every operating condition.

Actual backup duration depends on usable battery energy and average connected load. Lighting, communication equipment, selected appliances and other priority loads should be calculated from their normal operating power rather than only their nameplate peak value.

Wall Mounted Battery Specifications

2.56kWh Solar Battery FAQ

Is the nominal capacity 3kWh or 2.56kWh?

The formal specification lists 25.6V and 100Ah, which equals 2560Wh or 2.56kWh of nominal battery energy.

Can this battery work with a 24V inverter?

It may work with a compatible inverter after its battery-voltage range, charging voltage and DC current requirements are confirmed.

Can the battery continuously discharge at 150A?

No. The continuous discharge limit is 100A. The 150A value applies only to a one-second pulse condition.

Can the wall battery be installed outdoors?

No outdoor claim should be made. Its IP20 enclosure requires installation in a dry and protected indoor location.

How is the required battery runtime calculated?

Runtime depends on usable battery energy, average connected load, inverter efficiency and the configured discharge limits.
