5.12kWh 51.2V 100Ah Rack Mount LiFePO4 Battery With Front Cable Access
5.12kWh 51.2V Rack Mounted LiFePO4 Battery with Front Cable Access
This 5.12kWh rack mounted LiFePO4 battery provides a standard 51.2V, 100Ah storage module for residential solar systems, telecom backup, UPS applications and small commercial energy projects.
Its rack-format enclosure and front cable outlet support organized installation inside compatible equipment racks or protected battery areas. A separately selected inverter or charger is required.
Standard 5kWh Module for Scalable Systems
The 5.12kWh capacity provides a practical starting point for systems that need more stored energy than a compact 24V battery. Additional matching modules can be added when the project requires longer backup time or more daily solar storage.
The battery determines stored energy, while the external inverter determines AC output power. Module quantity should therefore be selected from daily consumption, required reserve and available charging capacity.
Front-Service Rack Arrangement
Power and communication connections are arranged at the front, allowing cables and status access to remain visible when the module is installed in a compatible rack.
The enclosure measures 486 × 483 × 153mm and weighs approximately 45kg. Rack load capacity, module spacing and cable clearance should be checked before installation.
Battery Current and Inverter Integration
Rated charging and discharging current is 50A. The specification also lists 100A continuous current and 105A for 10 seconds, with a rated battery power of 2.56kW.
RS485, RS232 and CAN interfaces support compatible inverter communication. The inverter’s voltage window, current demand and battery protocol should be reviewed before ordering.
Parallel Capacity Development
The specification recommends six batteries for common parallel installations and supports up to sixteen units. Larger configurations require suitable rack space, busbars, cables, protection and communication addressing.
The IP21 enclosure requires a dry indoor or protected technical location. Bluetooth is optional, and WiFi can be selected for remote battery data.

5.12kWh Rack Module FAQ
What is the benefit of front cable access?
It keeps power and communication connections accessible from the front of a compatible equipment rack.
How does this differ from a 25.6V battery module?
It uses a 51.2V platform and is intended for compatible 48V-class inverter systems.
Is one 5.12kWh battery sufficient for a solar project?
That depends on daily energy consumption, required backup time and the inverter’s battery-current demand.
Can the module be installed in a closed cabinet?
Yes, when the cabinet provides suitable load support, ventilation, cable clearance and protection from moisture.
Which details help calculate the required module quantity?
Provide daily energy use, backup duration, inverter model, charging capacity and available rack space.
