19-inch rack battery systems

6U Rack Battery Enclosures for 51.2V LiFePO4 Systems

A rack battery enclosure is designed to place a battery module inside a standard cabinet or equipment rack. The JKESS 6U kit is intended for compact LiFePO4 assembly projects where front service access, cabinet depth, airflow, parallel expansion, and inverter communication need to be planned before installation.

Form factor

6U, 19-inch rack-mount

Nominal platform

51.2V LiFePO4

Supported capacity

15kWh after compatible cells are installed

Communication

CAN 2.0 or RS485 with compatible BMS

Rack planning requirements

Rack compatibility is more than the nominal 19-inch width. Confirm usable cabinet depth, rail position, front and rear service access, cable routing, module weight, airflow, and the load rating of the rack and floor.

  • Measure cabinet depth and reserve clearance for terminals, breakers, and cable bends.
  • Check rack rail capacity and total floor loading when several modules are installed.
  • Plan module addresses, parallel current, busbars, breakers, and communication before expansion.
  • Provide the inverter model and required protocol for communication review.

Where rack battery enclosures are used

Common applications include residential solar backup, telecom rooms, small commercial backup systems, off-grid equipment rooms, and modular battery banks. The final completed battery must be engineered around the actual cells, BMS, inverter, protection equipment, and local installation requirements.

Enclosure-only or integrated electronics?

Select enclosure-only when cells, BMS, display, breakers, and wiring have already been validated as a complete design. Select the enclosure with LCD and BMS option when the project requires the specified JKESS monitoring and protection hardware. In both cases, cells remain excluded.

Frequently asked questions

Selection questions

Does 6U guarantee compatibility with every 19-inch rack?

No. The rack width standard does not confirm cabinet depth, rail position, service clearance, airflow, load capacity, or cable routing. Those dimensions must be checked before ordering.

Can several rack battery modules operate in parallel?

Parallel expansion can be planned, subject to the completed battery design, BMS addressing, inverter limits, breaker sizing, busbars, current sharing, cable selection, and commissioning requirements.

Is the listed 15kWh capacity a complete battery?

No. It is the supported assembled configuration after compatible cells and required electronics are installed. Battery cells are sold separately.
