Smart courtyard fully off-grid high-efficiency solar LED lighting landscape light array: large-area low-voltage DC bus loss reduction laying technology
The online consumer market is flooded with a large number of cheap split-type small solar lawn lamps. Because their internal micro batteries are easily damaged by water in the cold European environment, they have become a focus of negative reviews from overseas consumers. The EIP horticulture technology project team launched an advanced high-net-worth all-off-grid courtyard centralized lighting solution. We actually measured a long-distance centralized power supply network with a length of 50 meters using a central 24V low-voltage direct current (DC) bus. The system places a high-power 150W photovoltaic panel and a high-performance integrated off-grid box on the roof, and provides unified power supply through buried low-voltage lines. This solution completely eliminates the fragile small battery inside the split lamp, extending the system life to more than 8 years.
