Reliable Battery Performance for Home Energy Storage

This 51.2V 100Ah Stackable LiFePO4 Battery provides 5120Wh of nominal energy capacity per module. It supports 100A charge current and 100A discharge current, with a maximum discharge current of 200A for 10 seconds. The maximum discharge power is 5000W, making it suitable for residential solar storage, backup power, and small energy storage applications.

The battery uses 3.2V 100Ah cells in a 16S1P configuration. With a nominal voltage of 51.2V, charging voltage of 58.4V, and discharge voltage of 40V, it is designed for stable integration with compatible inverter systems. For project-based installations, buyers can confirm communication protocol matching before bulk procurement.

Communication and Inverter Compatibility

For B2B buyers, inverter communication compatibility is one of the key factors when selecting a stackable lithium battery. This 51.2V 100Ah Stackable LiFePO4 Battery supports optional RS485, RS232, and CAN communication, making it suitable for many inverter systems used in the residential solar storage market.

The built-in BMS supports multiple protection and communication functions, allowing real-time monitoring of battery data. This helps solar installers and system integrators improve system configuration, battery status monitoring, and long-term operation management.

Stackable Design for Flexible Energy Storage Expansion

The stackable structure is one of the main advantages of this battery model. Compared with a fixed single-cabinet battery, a stackable battery system allows users to configure capacity according to project requirements. This is useful for residential solar storage projects, distributor product lines, and installers who need flexible battery options for different end users.

The modular design also helps create a clean installation layout. Multiple battery modules can be stacked neatly to save floor space and support future system expansion. For solar installers and system integrators, this structure can make product selection and project configuration more flexible.
