Product Description

Product Parameters

The home-integrated photovoltaic energy storage system is a smart residential energy hub that combines highly efficient power generation, safe electricity storage, and intelligent energy management. Its outstanding performance stems from the parametric advantages and synergistic operation of three core hardware components: High-efficiency solar panels utilize advanced modules with a conversion efficiency of ≥24% and a power output exceeding 670W, coupled with low-temperature loss characteristics, ensuring maximum electricity generation from limited roof space. The smart inverter-controller, serving as the system's brain, minimizes energy loss with a conversion efficiency of ≥98% and features seamless grid-off switching within ≤20 milliseconds, guaranteeing uninterrupted power for critical loads during grid outages. The high-performance energy storage battery employs safe and reliable Lithium Iron Phosphate (LiFePO4) cells, offering a cycle life exceeding 6000 cycles. With a charge-discharge efficiency of ≥96.5% and a modular design, it delivers decades of stable energy storage and flexible capacity expansion. The entire system, coordinated through an intelligent management platform, can automatically execute strategies like "self-generation and self-consumption" and "peak-valley arbitrage," transforming sunlight into a reliable, around-the-clock, and profitable household power source. Ultimately, it provides users with significant electricity bill savings, worry-free power security, and the value of a green, low-carbon sustainable lifestyle.
