2.56kWh 51.2V Wall Mounted LiFePO4 Battery for Compact Solar Storage

Compact 51.2V Battery for Residential Solar Storage

This 2.56kWh wall mounted LiFePO4 battery combines a nominal voltage of 51.2V with a rated capacity of 50Ah. It is designed for compatible residential solar systems, backup power installations and low-voltage energy-storage projects where available wall and floor space must be used efficiently.

The wall-mounted enclosure measures 460 × 360 × 139mm and has a listed net weight of 23.2kg. Its compact format helps installers position the battery in a protected utility room, technical area or indoor energy-storage space without occupying a large section of the floor.

The battery supports up to 25A of continuous charging current and 50A of continuous discharge current. These limits should be matched with the connected inverter, battery cables, DC terminals and protection devices before the system is commissioned.

Practical Benefits for Compact Solar Installations

Inverter Matching and Battery Sizing

The connected inverter must support a nominal 51.2V battery and operate within the battery’s listed voltage range of 40.0–58.4Vdc. The inverter charging profile should also support the specified 56.0V floating-charge voltage.

The 25A continuous charging limit should be entered into the inverter or charger settings where applicable. A higher current setting is not supported by the formal specification and may activate battery protection.

The 50A continuous discharge limit must be compared with the inverter’s maximum DC demand. Installers should consider the total connected load, inverter efficiency, battery-cable length, conductor size and DC breaker or fuse rating.

Battery capacity determines expected operating duration rather than inverter output power. A 2.56kWh battery may suit selected essential loads, but the actual runtime depends on usable battery energy, average power demand and system settings.

Battery and Installation Specifications

2.56kWh Wall Mounted Battery FAQ

Is the actual nominal energy 3kWh?

The formal electrical rating is 51.2V and 50Ah, which equals 2560Wh or 2.56kWh of nominal energy.

Can it connect to a standard 48V inverter?

It may connect to a compatible inverter after its battery-voltage range, charging voltage and charging-current settings are confirmed.

Can the battery continuously supply 75A?

No. Continuous discharge is limited to 50A. The 75A value is specified only for a one-second pulse.

Can this battery be installed outside?

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

How should the wall installation be prepared?

The wall and mounting hardware must safely support the battery weight while leaving suitable access for DC cables, inspection and ventilation.
