Suitable Applications
The RUiXU RX-LFP48100-H is designed for compatible 48V residential energy storage, solar backup, off-grid systems, and other stationary battery-storage applications. Its rack-mount form factor and parallel expansion capability make it suitable for modular battery banks where additional storage can be added as system requirements increase.
Self-Heating & Cold-Weather Charging
The integrated heating system uses power from the charger to warm the battery before charging in cold conditions. The heater is rated at 480W and operates at 56V. Self-heating starts when battery temperature reaches approximately 41°F (5°C) or lower and stops when battery temperature reaches approximately 53.6°F (12°C).
Rack Mounting & Installation Options
The RX-LFP48100-H uses a 3U form factor measuring approximately 482 × 133.5 × 460mm. The battery can be installed using wall-mounted, floor-mounted, stacked, or rack-mounted configurations. Optional bracket racks and battery cabinets are available for different installation scenarios.
Parallel Expansion
The battery supports up to 32 units connected in parallel. This allows modular expansion from a single approximately 5kWh battery module to much larger energy-storage configurations. Proper parallel cabling, communication connections, overcurrent protection, and system configuration should be used when expanding the battery bank.
Inverter Communication
The battery includes RS485 and CAN communication interfaces. DIP address settings can be used to configure the RS485 baud rate and select the appropriate inverter communication protocol. Compatible CAN-based inverter systems 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 & Protection
The integrated Battery Management System provides protection against over-charge, over-discharge, and over-current conditions while helping maintain cell consistency through balancing functions. The battery also includes an inspection port for access to the BMS and fuse for maintenance requirements.
