5.12kWh 51.2V Wall Mounted LiFePO4 Battery for Scalable Solar ESS

This 5.12kWh wall mounted LiFePO4 battery provides 51.2V nominal voltage and 100Ah capacity for residential solar storage, backup power and compatible low-voltage energy storage systems. Its compact enclosure combines lithium battery storage, battery management and communication capability in a space-saving format for protected indoor installations.

RS485 and CAN communication support integration with compatible inverter platforms, while parallel expansion of up to 15 battery units allows system capacity to grow as project requirements increase.

5.12kWh Storage for Residential Solar and Backup

With 5.12kWh of nominal energy, a 51.2V battery platform and 100Ah rated capacity, this battery is designed for compatible residential solar systems, selected backup loads, off-grid installations and other applications requiring compact lithium energy storage.

The recommended charge current is up to 100A. The supplier specification lists a recommended maximum load power of up to 4kW and an ultimate maximum load reference of up to 5kW. Final inverter sizing, current limits and system configuration should always be checked for the complete installation.

Scalable Battery Capacity Up to 15 Units

Projects do not always require their final storage capacity on day one. This battery supports parallel expansion of up to 15 units, allowing installers and system integrators to build a larger battery bank from the same 5.12kWh module platform.

Expansion should be planned together with the inverter, battery addressing, cable sizing, protection devices, busbar arrangement and installation environment. Battery quantity and inverter compatibility should be confirmed before ordering.

CAN and RS485 Inverter Communication

RS485 and CAN interfaces provide communication options for compatible solar inverters and energy management equipment. Communication allows the battery and inverter to exchange operating information where the selected inverter protocol is supported.

Because communication protocols and firmware may vary between inverter brands and models, provide the exact inverter model before ordering so that battery communication compatibility can be reviewed.

Compact Indoor Battery Installation

The battery enclosure measures approximately 550 × 455 × 155mm and weighs about 47.15kg. Its slim profile is suitable for residential utility areas, solar equipment rooms and other protected technical spaces where installation footprint needs to be carefully managed.

The enclosure is rated IP21 and should be installed in a dry indoor or otherwise protected location. Charging is specified from 0°C to 45°C, while the discharge operating range is -20°C to 55°C.
