300AH 51.2V Solar Lithium Ion Battery

15KWH Power Wall LiFePO4 Batteries

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 51.2V314Ah 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 heavy loads like home appliances, commercial equipment, or industrial machinery-e.g., a 3000W device runs ~5 hours on a single charge, ensuring consistent power through nights, cloudy days, or grid outages.

Lithium-Ion Chemistry for Solar Compatibility Built with high-performance lithium-ion cells (often LiFePO4 variant, optimized for solar storage) that support 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 utilization of stored solar energy without damage.

Solar-Optimized BMS

: Guards against overvoltage (from solar panel spikes), undervoltage, overcurrent, short circuits, and thermal runaway-ensuring safe operation even with fluctuating solar input (e.g., sudden cloud cover or peak sunlight).

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

: Operates reliably in extreme temperatures (-20℃ to 60℃), outperforming lead-acid batteries in harsh environments like deserts, high-altitude regions, or cold climates-critical for outdoor solar installations.

High-Voltage & Space-Efficient Design Operates at 51.2V (4S configuration), reducing current flow compared to 12V/24V systems-minimizing energy loss in wiring and allowing thinner, more cost-effective cables for large setups. Weighs ~120kg (50% lighter than a 300AH lead-acid bank, which weighs 240kg+), with compact dimensions (e.g., 80cm x 60cm x 25cm) that save floor space in solar sheds or utility rooms.
