51.2V 280Ah 314Ah Lifepo4 Lithium Battery

15KWH 16KWH 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.

Dual-Capacity Options for Tailored Home Energy Needs

Offered in 280Ah and 314Ah variants, the battery delivers scalable energy storage to match diverse residential demands:

280Ah (14.336kWh): Powers a typical household's critical loads (refrigeration, lighting, Wi-Fi, small appliances) for 1–2 days, or supports partial solar self-consumption (offsetting 50–60% of daily grid use) for homes with 3–5kW solar arrays.

314Ah (16.172kWh): Extends backup runtime to 2–3 days for critical loads, or enables full solar self-consumption (offsetting 70–80% of daily grid use) for larger homes with 5–7kW solar arrays.Both options operate at 51.2V nominal voltage (58.4V max charge voltage), reducing current flow for the same power output-minimizing energy loss via cables (by up to 25% vs. 12V/24V batteries) and compatible with 3–8kW residential inverters (grid-tie or off-grid).

LiFePO4 Chemistry for Long Lifespan & Safety

Built with premium LiFePO4 cells, the battery outperforms traditional lead-acid or other lithium-ion alternatives in durability and safety:

Extended Cycle Life: 3000–6000 deep cycles at 80% depth of discharge (DoD), retaining ≥80% capacity after 10–15 years-5–10x longer than lead-acid batteries, eliminating frequent replacement costs.

Inherent Safety: Non-flammable, non-explosive chemistry (unlike Li-ion) with a wide operating temperature range (-20°C to 60°C), avoiding thermal runaway risks even in overcharge, short-circuit, or high-temperature scenarios.

High Charge/Discharge Efficiency: 95–98% round-trip efficiency (vs. 70–80% for lead-acid), meaning more solar energy is stored and used rather than wasted as heat-maximizing the value of every kWh captured.
