Suitable Applications
The RUiXU RX-LFP48100 is designed for compatible 48V residential energy storage, solar backup, off-grid power systems, and stationary battery-storage applications. Its 3U rack format, communication interfaces, and parallel expansion capability make it suitable for modular battery banks installed in racks, cabinets, or other approved mounting configurations.
Rack Mounting & Installation
The RX-LFP48100 uses a 3U form factor measuring approximately 482 × 133.5 × 460mm. It supports wall-mounted, floor-mounted, stacked, and rack-mounted installation methods. Optional bracket racks and battery cabinets can be used for different installation configurations.
Parallel Expansion
Up to 32 compatible RX-LFP48100 batteries can be connected in parallel. This allows the system to expand from a single approximately 5kWh battery module to a much larger energy-storage bank. Use appropriate parallel cables, communication connections, overcurrent protection, and compatible system components when expanding the battery bank.
Inverter Communication
The battery includes RS485 and CAN communication interfaces. DIP address settings are used to select the RS485 baud rate and compatible inverter communication protocol. Supported CAN inverter brands listed in the supplied documentation include Victron, SMA, Studer Innotec, Sofar, Sol-Ark, Solis, GoodWe, Deye, Growatt, SAJ, LuxPower, Megarevo, INVT, Sermatec, TBB, MUST, Sunsynk, and Schneider. RS485 support is listed for MPP, Voltronic, RCT, and Alpha Outback systems.
Smart BMS & Cell Balancing
The integrated Battery Management System provides protection against over-charge, over-discharge, and over-current conditions. The BMS also supports cell balancing to help maintain consistency between battery cells during operation.
Quick-Plug & Maintenance Access
The battery uses quick-plug connections designed for convenient installation and includes up to 250A continuous overcurrent capacity. A dedicated maintenance and inspection port provides access to the BMS and fuse for service requirements.
Indoor Installation
The supplied technical specification identifies the RX-LFP48100 as an IP20 battery intended for indoor installation. Install the battery in a dry, protected location with appropriate ventilation and secure mounting, and keep it away from rain, standing water, and direct environmental exposure.
Important Usage Note
Actual usable energy, cycle life, charging performance, and battery output can vary with inverter compatibility, depth of discharge, charge and discharge rate, temperature, wiring, and installation conditions. The supplied documentation notes that system usable energy may vary by inverter brand and that derating can occur at certain operating temperatures. Verify battery voltage, charge and discharge limits, communication protocol, inverter compatibility, and installation requirements before commissioning.
