Suitable Applications

These RUiXU lithium battery kits are designed for compatible residential solar energy storage, backup power, and off-grid systems. The modular rack-based configuration is suitable for installations where battery capacity needs to be expanded in defined stages while maintaining inverter communication and organized battery-bank wiring.

Self-Heating & Cold-Weather Charging

The RX-LFP48100-H battery includes a built-in 480W heating system that draws power from the charger. Self-heating starts when the battery temperature reaches approximately 41°F (5°C) or below and stops at approximately 53.6°F (12°C). This feature is intended to support charging in cold environments within the battery's specified operating conditions.

Rack Cabinet Installation

Each kit includes a pre-assembled 6-slot battery cabinet. The supplied RUiXU product documentation also shows three installation approaches for the battery platform, including bracket-rack, 6-slot cabinet, and 10-slot cabinet configurations. The 6-slot cabinet is identified for 5kWh–30kWh battery kits, while the 10-slot cabinet is shown for larger 5kWh–50kWh configurations.

Inverter Communication

The RX-LFP48100-H uses RS485 and CAN communication interfaces for compatible inverter systems. DIP address settings allow configuration of the RS485 baud rate and inverter protocol. CAN compatibility is listed for Victron, SMA, Studer Innotec, Sofar, Sol-Ark, Solis, GoodWe, Deye, Growatt, SAJ, LuxPower, Megarevo, INVT, Sermatec, TBB, MUST, Sunsynk, and Schneider. RS485 compatibility is listed for MPP, Voltronic, RCT, and Alpha Outback systems.

Parallel Expansion

The individual battery modules can be connected in parallel, with the platform supporting up to 32 units. Parallel expansion allows the system to grow beyond the supplied 15kWh, 20kWh, 25kWh, and 30kWh configurations when additional compatible batteries, communication wiring, protection equipment, and installation capacity are available.

Smart BMS & Protection

The integrated BMS provides protection against over-charge, over-discharge, and over-current conditions while supporting battery cell balancing. The battery also uses quick-plug connections with up to 250A continuous overcurrent capacity for convenient system wiring.

Included Components

Each kit includes the specified number of RX-LFP48100-H self-heating server rack batteries, matching RJ45/CAT5e communication cables, grounding cables, parallel 4AWG battery cables, and one pre-assembled 6-slot battery cabinet.

Installation & Operation

The RX-LFP48100-H battery is specified for indoor installation with an IP20 enclosure rating. Install the battery cabinet in a dry, protected location with appropriate clearance, ventilation, grounding, overcurrent protection, and communication connections. Match the inverter and charging equipment to the battery's voltage, current, and communication requirements before commissioning.

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 supplied documentation notes that usable energy may vary by inverter brand and that derating can occur within certain temperature ranges. Verify all battery, inverter, cabinet, wiring, protection, and local installation requirements before commissioning.
