51.2V 100Ah Wall Mount LiFePO4 Battery 5.12kWh Solar Storage With LCD Display

The YF51100WM is a wall-mount lithium iron phosphate (LiFePO₄) battery engineered for home energy storage systems. With 51.2V nominal voltage and 100Ah capacity (5.12kWh), this unit provides reliable, safe power for solar self-consumption, backup during grid outages, and off-grid applications.

Integrated features include a smart BMS with comprehensive protection, LCD display for real-time status monitoring, and RS485/CAN communication ports for seamless compatibility with most hybrid inverters. The durable sheet metal chassis with IP55 protection allows for indoor or covered outdoor installation.

• No thermal runaway, no fire risk – safer than NMC or lead-acid
• ≥6000 cycles @ 0.3C, 80% DoD – designed for 10+ years of daily use
• Low self-discharge, maintenance-free operation

• Prevents overcharge, over-discharge, over-current, short circuit, and temperature extremes
• Active cell balancing extends battery life and maintains usable capacity
• BMS communicates with inverters via RS485 and CAN for optimal performance

• Shows voltage, state of charge (SOC), current, temperature, and fault codes
• Reduces support calls – homeowners can check status without an app

• Works with most mainstream hybrid and off-grid inverters (Victron, Deye, Growatt, Solis, Sungrow, Sofar, etc.)
• Communication protocol documentation provided to integrators

• Dust-protected and resistant to low-pressure water jets
