Meet the Haisic HS-LD15KW-A2, a powerful 15.6kWh lithium-ion battery built with LiFePO₄ (Lithium Iron Phosphate) chemistry for premium energy storage, ultra-long lifespan, and intelligent control. Designed for seamless integration with both residential and commercial solar systems, this battery supports large energy demands with ease, offering 305Ah capacity, 51.2V nominal voltage, and compatibility with top-tier inverters.

This battery is not only high-performing but also smart and durable, with advanced communication ports (RS485 & CAN), a digital LED+LCD interface, and a robust housing structure.

Performance Comparison vs. Traditional Lead-Acid Batteries:

The Haisic 15kWh battery delivers up to 10 times longer lifespan with over 6000 charge-discharge cycles, while lead-acid batteries typically fail after just 500 cycles. While lead-acid systems lose efficiency with deep discharges, this lithium battery can be safely used up to 80% of its capacity every day without degrading performance.

It also supports faster charging, handling up to 200A of charge and discharge current, ideal for fast-paced energy demands. In contrast, lead-acid batteries are slower to recharge and suffer from energy losses. The Haisic unit is maintenance-free, leak-proof, and operates silently, unlike bulky, corrosive lead-acid counterparts.
