Suitable Applications
The RUiXU RX-LFP48100-H is designed for compatible residential energy storage, solar battery systems, backup power, and off-grid installations. Its 3U rack format, self-heating function, communication interfaces, and 32-unit parallel capability make it suitable for modular battery banks in racks and compatible battery cabinets.
Self-Heating & Cold-Weather Charging
The RX-LFP48100-H includes a 480W heating system operating at 56V. The heating elements draw power from the charger and begin heating when the battery temperature is at or below approximately 41°F (5°C), stopping when the battery reaches approximately 53.6°F (12°C). The supplied product information identifies the battery as a cold-weather charging model with integrated heating support.
Rack Mounting & Installation
The battery uses a 3U, 19-inch rack-mounted format measuring approximately 482 × 133.5 × 460mm. It supports wall-mounted, floor-mounted, stacked, and rack-mounted installation methods. Optional bracket kits can be used for different installation scenarios.
Parallel Expansion
Up to 32 compatible RX-LFP48100-H batteries can be connected in parallel. This allows a single 5.12kWh battery module to be expanded into a much larger energy-storage bank when appropriate battery cables, communication wiring, overcurrent protection, and compatible inverter equipment are used.
Inverter Communication
The battery includes RS485 and CAN communication interfaces. DIP address settings allow selection of the RS485 baud rate and compatible inverter communication protocol. CAN communication is listed for Victron, SMA, Studer Innotec, Sofar, Sol-Ark, Solis, GoodWe, Deye, Growatt, SAJ, LuxPower, Megarevo, INVT, Sermatec, TBB, MUST, Sunsynk, and Schneider systems. RS485 compatibility is listed for MPP, Voltronic, RCT, and Alpha Outback systems.

Important Usage Note
Actual usable energy, charging performance, discharge capability, cycle life, and system capacity can vary with inverter selection, depth of discharge, charge and discharge rate, temperature, wiring, and installation conditions. The manufacturer's documentation notes that system usable energy may vary by inverter brand and that derating can occur at certain temperatures. Verify battery, inverter, charger, communication, wiring, protection, and installation requirements before commissioning.
