Suitable Applications

These RUiXU battery kits are designed for compatible residential energy storage, solar battery systems, backup power, and off-grid installations. The rack-based modular configuration allows multiple 48V LiFePO4 batteries to be installed together in a cabinet and expanded as energy-storage requirements increase.

Self-Heating & Cold-Weather Charging

The RX-LFP48100-H includes a 480W heating system that draws power from the charger. The self-heating function starts at or below approximately 41°F (5°C) and stops when the battery reaches approximately 53.6°F (12°C), providing cold-weather charging support within the battery's specified operating conditions.

Battery Cabinet Installation

Each listed configuration includes a pre-assembled 6-slot battery cabinet. The RUiXU platform also supports optional bracket-rack and larger cabinet installation methods, allowing different battery-bank layouts based on available space and system capacity.

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 communication 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.

Parallel Expansion

The battery platform supports up to 32 units connected in parallel. Parallel expansion allows larger energy-storage configurations beyond the supplied 15.36kWh, 20.48kWh, 25.60kWh, and 30.72kWh kits when additional compatible batteries, wiring, protection equipment, and installation capacity are available.

Smart BMS & Protection

The integrated Battery Management System provides protection against over-charge, over-discharge, and over-current conditions while supporting cell balancing. Quick-plug connections provide up to 250A continuous overcurrent capacity and are designed for convenient tool-less battery connections.

Included Components

Each kit includes the specified number of RX-LFP48100-H self-heating server rack batteries, matching RJ45/CAT5e communication cables, ground cables, 30cm parallel 4AWG cables, and one pre-assembled 6-slot battery cabinet.

Installation & Operation

The RX-LFP48100-H is specified as an IP20 indoor battery. Install the battery cabinet in a dry, protected location with appropriate clearance, ventilation, grounding, overcurrent protection, and communication connections. Ensure the selected inverter and charging equipment are configured for 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. Follow the manufacturer's battery, inverter, cabinet, wiring, protection, and communication requirements when installing and configuring the system.
