Hinen B5000 5.12kWh 51.2V LiFePO4 Low Voltage Battery

Product Overview

The Hinen B5000 is a low-voltage lithium iron phosphate (LiFePO4) battery module designed for residential and small commercial energy storage systems. With a nominal voltage of 51.2V and a rated energy capacity of 5.12kWh, the Hinen B5000 is intended for use with compatible low-voltage hybrid and off-grid inverters that support CAN communication.

What This Battery Is

The Hinen B5000 is a rechargeable low-voltage battery module used for storing electrical energy in solar and backup power systems. It operates as part of a battery bank and supplies DC power to a compatible inverter during grid outages or when solar generation is unavailable.

What This Battery Is Not

The Hinen B5000 is not an inverter and cannot convert DC power to AC power on its own. It is not a high-voltage battery and must not be connected to high-voltage battery systems. It does not include an internal inverter, MPPT, or grid interface.

System Compatibility and Application

This battery is designed for low-voltage battery systems operating at 48V nominal. It is suitable for residential backup power, hybrid solar systems, and off-grid installations where scalable battery storage is required. The battery communicates with compatible inverters using CAN communication for safe charging, discharging, and system monitoring.

Battery Chemistry and Operating Concept

The Hinen B5000 uses lithium iron phosphate (LiFePO4) chemistry, selected for thermal stability, long cycle life, and improved safety compared to other lithium-ion chemistries. The battery operates within a controlled voltage range and uses an internal battery management system to manage cell balancing, protection, and communication with the inverter.

Scalability and Parallel Operation

Up to six Hinen B5000 battery modules can be connected in parallel, allowing system expansion from a single 5.12kWh module up to larger usable capacities depending on system design. Parallel operation maintains the same system voltage while increasing total stored energy.
