51.2V 300AH Solar Lithium Battery Pack

15KWH Power Wall LiFePO4 Batteries

This 51.2V 314Ah LiFePO4 Battery is a high-capacity lithium iron phosphate energy storage battery designed for residential solar systems, commercial energy storage and off-grid backup power solutions. Featuring stable 51.2V and 314Ah large capacity, it delivers long cycle life, high safety performance and excellent deep discharge capability, perfectly matching hybrid solar inverters for home, villa, farm and industrial energy storage projects.

300AH (15.36KWh) High-Capacity Storage Provides 300 amp-hours of fully usable capacity at 51.2V (15.36KWh total energy), with a continuous discharge current of 300A (surge up to 600A for 5 seconds). Stores solar energy to power large off-grid homes, commercial facilities, or industrial equipment-e.g., a 3000W load runs ~5 hours on a single charge, ensuring reliable power through nights or cloudy days.

LiFePO4 Chemistry for Solar Compatibility Built with lithium iron phosphate (LiFePO4) cells, optimized for solar energy storage with 3000+ deep cycles at 100% depth of discharge (DoD). Unlike lead-acid batteries (limited to 500 cycles at 50% DoD), it retains 80% of original capacity after 10+ years-critical for solar systems where frequent deep cycling is common. Safe for full discharge, maximizing use of stored solar energy without damage.

Solar-Optimized BMS

Comprehensive Protection: Guards against overvoltage (from solar panels), undervoltage, overcurrent, short circuits, and thermal runaway-ensuring safe operation even with fluctuating solar input.

MPPT Compatibility: Works seamlessly with 51.2V solar inverters and MPPT charge controllers, regulating charging current to match solar panel output (e.g., adjusting for varying sunlight intensity) and preventing overcharging during peak sunlight.

Cell Balancing & Temperature Control: Automatically equalizes cell voltages to maintain performance, while operating in extreme temperatures (-20°C to 60°C)-critical for outdoor solar installations in deserts, high altitudes, or cold climates.
