YF51100 5KW Wall-Mounted Solar Battery Storage System 5.12kWh LiFePO4 Backup

The YF51100-5KW All-in-One Wall-Mounted Energy Storage System integrates high-capacity LiFePO4 battery technology with a powerful hybrid inverter, delivering seamless backup power and solar energy optimization for modern homes. With 5.12kWh of usable energy and a 5000W pure sine wave inverter in a slim wall-mounted design, this system simplifies home energy management while providing uninterrupted power and reduced electricity bills.

Combines a 5.12kWh LiFePO4 battery and 5kW hybrid inverter in a single wall-mounted unit (790x520x222mm), eliminating bulky racks and complex wiring while maintaining an aesthetic appearance.

Factory pre-wired and pre-configured for plug-and-play operation, reducing installation time and costs while providing intuitive user interface and automatic functionality.

Features a 6000W MPPT solar charger with wide PV input range (120-450Vdc) and 100A charging current, maximizing solar energy harvest while supporting 80A AC charging from grid or generator.

Fast transfer switching in just 10ms (PC mode) or 20ms (appliance mode) ensures continuous operation of computers, routers, and sensitive electronics during grid outages.

Supports parallel operation of up to 6 units for expanded capacity up to 30kW output, making it suitable for larger homes and light commercial applications.

WiFi or GPRS monitoring enables real-time tracking of solar generation, battery status, consumption, and system health via dedicated app or web portal.

Built with automotive-grade LiFePO4 cells and multi-layer BMS, featuring comprehensive protection and certified to UN38.3, MSDS, CE, UL, and EN61000 standards.
