Designed to integrate seamlessly with mainstream inverters, the RX-LFP48100 allows homeowners and installers to build flexible, high-capacity storage systems without external controllers.

Key Features

Modular & Scalable Design: Supports up to 32 batteries in parallel, allowing expansion from 5kWh to 160kWh without additional controllers.
Ultra-Slim 3U Rack Form Factor: Compact 3U (133mm height) fits standard 19-inch racks, saving space while maintaining high energy density. Dimensions: 482 × 460 × 133.5mm
Multiple Installation Options:
- Rack mounted
- Floor mounted
- Wall mounted
- Stack mounted
- Optional bracket kits available for different installation scenarios
Intelligent BMS with Advanced Protection:
- Over-charge protection
- Over-discharge protection
- Over-current protection
- Automatic cell balancing for long-term reliability
Inverter Protocol Selection: DIP switch addressing configures RS485 baud rate and inverter communication protocols for broad inverter compatibility.
High-Capacity Pre-Charge Capability: Built-in 1,000,000µF pre-charge circuit enables safe startup with high-power inverters, reducing stress on components.
Optional Built-In Heater:
- Charging temperature range: -5°C to 59°C

Understanding Your Power Needs

Power Calculation Guide

Sizing Metric	Formula & Example
Energy Consumption (Wh)	Formula: Watts × Hours Example: 60W × 4 hrs = 240 Wh
Battery Capacity (Ah)	Formula: Watt-hours ÷ System Voltage (V) Example: 240 Wh ÷ 12V = 20 Ah
Inverter Size (W)	Formula: Total Watts × 1.25 (safety margin) Example: 300W × 1.25 = 375W → Use 400W inverter
Total Load Power (W)	Formula: Sum of all appliance watts used simultaneously Example: Light (10W) + Fan (75W) = 85W
Runtime (hrs) of Battery	Formula: (Battery Ah × Voltage) ÷ Total Load (W) Example: (100Ah × 12V) ÷ 240W = 5 hrs

Find Your Power Match

Need / Application	System Recommendation
Basic lighting + phone charging	Recommended Battery: 50Ah – 100Ah (12V) Inverter Size: 100W – 200W Notes: For small backup setups
Home office (laptop, fan, TV)	Recommended Battery: 150Ah – 200Ah (12V or 24V) Inverter Size: 500W – 1000W Notes: For moderate usage with 4–6 hours of backup
Home backup (fridge, lights)	Recommended Battery: 200Ah+ (24V or 48V recommended) Inverter Size: 1000W – 1500W Notes: Ideal for longer backups or heavier loads
Business / shop power backup	Recommended Battery: 300Ah+ (48V system) Inverter Size: 2000W – 3000W Notes: Suitable for commercial setups or extended power outages
