5.12kWh Energy Storage Battery – Stacked LiFePO₄ System

Smart Energy Storage for Off-Grid and Backup Power

This 5.12kWh energy storage system provides clean, reliable power for solar, backup, and off-grid use. It runs on 48V and offers 100Ah capacity. The stacked design makes it easy to install. You can also add more units to increase storage. This system is ideal for solar storage, telecom backup, or off-grid cabins.

The battery uses Lithium Iron Phosphate (LiFePO₄). This chemistry is known for safety, thermal stability, and long life. You can expect over 6,000 charge cycles at 80% depth of discharge. It includes a 100A Smart BMS that communicates through RS485, RS232, or CANBus to help you monitor your system in real time.
