Why Choose the Rakour 51.2V 200Ah Low Voltage Server Rack Battery
A purpose-built 10.24kWh LiFePO4 module for low voltage battery inverter systems, delivering proven performance in residential and small commercial energy storage installations.
Built on Grade-A LiFePO4 Cells
Rakour uses Grade-A lithium iron phosphate cells rated for over 6,000 deep cycles at 90% DOD. This chemistry is inherently stable, non-flammable, and holds consistent capacity through years of daily cycling.
Compact Rack-Mount Design That Saves Space
At 605×383×240 mm and 77 kg, this low voltage battery fits standard server racks directly. The front-panel LCD touch screen displays real-time SOC, voltage, and current for quick status checks.
5-Year Warranty and Global Environmental Coverage
Every unit passes full charge-discharge and cell-level voltage testing before shipment. Rakour backs the 51.2V 200Ah server rack battery with a 5-year warranty and covers operating temperatures from −20°C to 60°C.
Full Technical Specifications of the 200Ah Lithium Battery
All parameters needed to verify system compatibility and accurately size your installation — from core electrical ratings and physical dimensions to supported communication interfaces and certifications.
Core Electrical Parameters
Nominal voltage: 51.2V. Capacity: 200Ah. Total energy: 10.24kWh. Usable energy at 90% DOD: 9.22kWh. Charging voltage: 57.6V. End-of-discharge voltage: 46.4V. Maximum continuous discharge current: 120A. Peak power output: 6,144W.
Physical Dimensions and Environmental Ratings
Dimensions: 605×383×240 mm (W×D×H). Net weight: 77 kg. Protection level: IP20. Working altitude: ≤2,000 m. Humidity: ≤85% RH. Discharge temperature range: −20°C to 60°C. Charge temperature range: 0°C to 60°C.
10kWh Battery Communication Ports
CAN, RS485, and RS232 interfaces are factory-fitted on every unit. CAN and RS485 enable direct BMS-to-inverter communication for fully automated charge and discharge control. The RS232 port connects to a PC for parameter reading and configuration.
Smart BMS Battery Management System: Multi-Layer Cell Protection
The built-in battery management system monitors every cell in real time, triggering automatic protection and active balancing to maximize safety and extend pack lifespan.
What the LiFePO4 BMS Monitors in Real Time
The BMS simultaneously tracks individual cell voltage, total pack current, and cell temperature. When any value exceeds safe limits, the BMS disconnects the circuit within milliseconds — protecting both the battery and the connected inverter.
Six Built-In Protection Functions
Overcharge and over-discharge cutoffs prevent cell damage at voltage extremes. Over-current and short-circuit protection respond instantly to load spikes. High- and low-temperature lockout halts operation outside the safe thermal range automatically.
Active Cell Balancing to Extend LiFePO4 Battery Life
All 16 series cells are equalized every charge cycle. Cells reaching full voltage early are bled down so the entire pack completes charging simultaneously — directly sustaining the rated 6,000-cycle lifespan.
Scalable Parallel Expansion and Inverter Compatibility
Connect up to 15 units in parallel to scale from 10.24kWh to 153.6kWh total capacity, with native CAN/RS485 communication supported across all major low-voltage inverter brands.
How the 48V 200Ah Lithium Battery Parallel System Works
Each unit connects via the RS485-2 port using a standard RJ45 cable. The BMS auto-detects added modules, synchronizes SOC across the bank, and distributes load evenly — preventing any single unit from over-cycling.
Supported Inverter Brands and Protocols
The server rack battery natively supports CAN and RS485 protocols, enabling direct communication with Deye, Growatt, Victron, Luxpower, and Goodwe inverters. No third-party protocol adapters or custom firmware modifications are required.
LV vs HV: Choosing the Right System Voltage
This model operates at 51.2V nominal, suited for low voltage battery inverters under 60V. For larger commercial installations requiring higher voltage, Rakour offers a dedicated high-voltage series in the same rack form factor.
Safety Certifications and Quality Assurance You Can Verify
Every Rakour 51.2V 200Ah server rack battery ships with internationally recognized certificates, giving installers and end-users documented proof of compliance.
CE, RoHS, IEC62619, UN38.3, and MSDS Certified
The 51.2V 200Ah-LV holds CE, RoHS, IEC62619, UN38.3, and MSDS certifications. IEC62619 governs lithium battery safety for stationary storage, confirming resistance to overcharge, short-circuit, and thermal abuse under internationally recognized test conditions.
Grade-A Cell Sourcing and Pre-Shipment Testing Protocol
Rakour sources Grade-A LiFePO4 cells and runs each unit through cell voltage, pack current, and full charge-discharge testing before shipment. No battery leaves the factory without passing every step of the quality inspection protocol.
5-Year Warranty as a Documented Trust Commitment
The 5-year warranty covers manufacturing defects and abnormal capacity degradation. It reflects Rakour confidence in long-term cell and BMS reliability, providing documented recourse for distributors and system integrators operating in global markets.
Where This Battery Storage System for Solar Fits Best
The 51.2V 200Ah LV rack battery matches the energy demands of real-world low-voltage residential, off-grid, and small commercial systems.
Residential Solar Energy Storage
One unit delivers 9.22kWh of usable daily storage, covering typical evening household loads. Additional units stack in parallel, letting homeowners scale capacity incrementally without replacing existing inverter hardware or rewiring the system.
Small Commercial and Off-Grid Backup Power
Telecom shelters and off-grid sites benefit from the 120A discharge rating and −20°C to 60°C operating range. Up to 15 parallel units deliver 153.6kWh of resilient backup for mission-critical commercial loads.
LiFePO4 Solar Battery Replacement for Lead-Acid Banks
This unit fits existing 48V rack infrastructure, replacing lead-acid banks at equivalent voltage while delivering three times the usable capacity per kilogram. No rack modification or inverter reconfiguration is needed for most standard installations.
Rack Mount Battery Backup: Step-by-Step Installation Overview
Designed for qualified electricians, the Rakour 51.2V 200Ah rack battery follows a clear commissioning sequence ensuring safe startup and full BMS communication from first power-on.
Pre-Installation Inspection Checklist
Inspect packaging for holes or cracks before unpacking. Confirm accessories are present: power cables, RJ45 communication cables, mounting ear sheet metal, and M4 screws. Contact your distributor if any item is missing or visibly damaged.
Physical Mounting and Ventilation Requirements
Install indoors on a fire-resistant surface with 300 mm clearance on all sides. Secure with mounting ear sheet metal and M4 screws. Complete grounding before connecting any power or communication terminals to the inverter.
Connecting Power, Communication, and Parallel Cables
Connect terminals to the inverter using supplied 4AWG cables. Plug the CAN or RS485 RJ45 cable into the inverter port. For parallel setups, daisy-chain the RS485-2 port between units with the included RJ45 parallel cable.
