Reliable Battery Performance for Energy Storage Projects

This 51.2V 300Ah LiFePO4 Battery is designed for stable energy storage performance in solar power systems. With a nominal voltage of 51.2V DC and nominal capacity of 300Ah, it provides 15,360Wh of energy storage capacity. The battery supports a recommended charge current of 100A and a maximum charge current of 200A. For discharge applications, it also supports a recommended discharge current of 100A and a maximum discharge current of 200A.

For system protection and long-term operation, the battery is equipped with an intelligent BMS. The BMS helps monitor battery status and protect the system from common electrical risks during charging and discharging. This makes the battery suitable for installers and energy storage solution providers who require stable performance and easier system integration.

Communication and Inverter Compatibility

For B2B energy storage projects, communication compatibility is one of the most important purchasing factors. This 51.2V 300Ah LiFePO4 Battery supports CAN, RS485, and RS232 communication protocols, making it easier to connect with solar inverters, hybrid inverter systems, and energy management devices.

The battery can be used in residential solar storage systems, off-grid solar power systems, backup power systems, and small commercial energy storage solutions. For inverter matching, communication protocol configuration, or project-based system design, buyers can contact our technical team before placing bulk orders.

Scalable Design for Parallel Battery Systems

The LD 48300 battery supports up to 15 units in parallel, allowing users to expand the energy storage capacity according to project requirements. This is useful for solar installers, distributors, and system integrators who need flexible battery configurations for different residential or commercial applications.

Compared with a fixed-capacity battery solution, a parallel battery system gives project buyers more flexibility. The system can start with a smaller number of battery units and expand later when higher storage capacity is required. This makes the product suitable for both standard home energy storage systems and customized energy storage projects.
