Rack Mounted Lithium Iron Battery — A New Benchmark for System-Level Energy Storage

With the rapid acceleration of the global energy transition and the growing demand for distributed energy storage systems, reliable, safe, and scalable battery solutions have become essential for modern power applications. The R-PRO Series Rack Mounted Lithium Iron Phosphate (LiFePO4) Battery by ONESUN is designed to meet these evolving market demands, delivering high-performance energy storage solutions for global residential, commercial, and industrial systems.

The R-PRO Series features a standard 19-inch rack-mounted design, making it easy to integrate into server racks, commercial cabinets, power equipment rooms, data centers, off-grid solar systems, and hybrid energy storage installations. Its modular and intelligent architecture enhances system reliability while simplifying maintenance and future capacity expansion.



Multiple Models to Meet Diverse Energy Storage Needs

The R-PRO Series is available in the following configurations:

* R-25.6V 200Ah
* R-51.2V 100Ah / 200Ah / 314Ah

All models are built with advanced Lithium Iron Phosphate (LiFePO4) chemistry, known for superior safety, long cycle life, and stable performance. These batteries are suitable for applications ranging from small-scale solar storage systems to large-capacity commercial and industrial energy storage projects.

The 25.6V 200Ah model offers a flexible low-voltage solution for specialized equipment and customized systems. Meanwhile, the 51.2V series (48V class lithium battery) is widely adopted in residential solar energy storage, commercial backup power systems, and industrial ESS projects due to its high energy density and easy scalability through parallel connections.



Key Features and Technical Advantages

High Safety and Intelligent Protection

The R-PRO Series combines premium LiFePO4 battery cells with an advanced Battery Management System (BMS). LiFePO4 chemistry provides excellent thermal stability and a significantly lower risk of thermal runaway compared to other lithium technologies. The intelligent BMS continuously monitors voltage, current, temperature, and overall battery status, ensuring protection against overcharge, over-discharge, short circuit, overcurrent, and extreme temperature conditions. This multi-layer protection system guarantees safe and stable long-term operation.



Modular Rack Design for Easy Expansion

Designed with a standard rack structure, each battery module can be installed horizontally in 19-inch cabinets and connected in parallel to expand total system capacity. This modular architecture allows users to scale their energy storage system according to project requirements without replacing the entire system, reducing initial investment costs and improving long-term flexibility.



Long Cycle Life and High Durability

Thanks to high-quality LiFePO4 cells, the R-PRO Series delivers over 6000 cycles at 80% Depth of Discharge (DOD). Compared with traditional lead-acid batteries, this significantly extends service life, reduces maintenance frequency, and lowers the total cost of ownership over time.



Smart Monitoring and Easy Integration

The battery system supports standard communication protocols such as RS485 and CAN (optional multi-protocol compatibility), enabling seamless integration with inverters, Energy Management Systems (EMS), and monitoring platforms. Real-time data collection, remote diagnostics, and intelligent system optimization improve operational efficiency and simplify maintenance.
