51.2V Stackable All-in-One Energy Storage System

51.2V Stackable All-in-One Energy Storage System is a modular LiFePO4 battery storage solution for off-grid solar, residential backup and distributed energy storage, combining flexible capacity expansion, intelligent BMS protection and broad inverter compatibility in a stackable design.

Core Advantages:

1. Modular Stackable Design

The Stackable Energy Storage System uses 51.2V/100Ah battery modules that can be stacked from 1 to 4 units. This allows buyers to select 5.12kWh, 10.24kWh, 15.36kWh or 20.48kWh configurations according to project requirements.

2. Long Cycle Life

Built with LiFePO4 battery technology, the Stackable All-in-One ESS supports more than 6,000 deep charge and discharge cycles, providing a durable solution for long-term solar energy storage and backup applications.

3. Intelligent BMS Protection

The integrated Battery Management System continuously monitors battery operating conditions and provides overcharge, over-discharge, over-voltage, over-current, short-circuit and over-temperature protection.

4. Ultra-Low Standby Power Consumption

The battery is designed for energy-efficient operation with standby self-consumption as low as 4mA, helping minimize unnecessary energy loss when the system is not actively charging or discharging.

5. Intelligent Safety Sleep Mode

When there is no charge or discharge activity for 30 days, the system can automatically disconnect the output to improve long-term storage safety. Manual output disconnection is also supported.

6. Wide Inverter Compatibility

RS485 and CAN communication interfaces support integration with major inverter brands, including Deye, Growatt, Voltronic, GOODWE, VICTRON, PYLONTEC, SMA and SOFAR, making the Stackable Energy Storage System suitable for different system integration projects.

7. IP54 Protection

The IP54 enclosure provides protection against dust and water splashes, supporting reliable operation in suitable indoor and protected installation environments.

8. Designed for Off-Grid Solar Systems

The Stackable All-in-One ESS is particularly suitable for off-grid solar power systems, providing stable battery storage for homes, remote locations and other applications where reliable backup power is required.
