Remote power supply energy-saving type for base station use
Battery Energy Storage System (BESS): Use high-performance lithium batteries or other types of energy storage devices to store excess power to ensure continuous power supply even when there is no light or wind. Remote base stations and telecom towers often face significant challenges when it comes to a consistent, reliable power supply. Many of these sites operate far from conventional grids, making traditional power methods costly and environmentally impactful. However, in the past, the off-grid BSs usually relied on emission-intensive power supply solutions such as diesel. For base stations located in deserts or other extreme environments, independent power supply is essential, as these areas are not only beyond the reach of power grids but also unsuitable for fuel generators due to the lack of on-site personnel for maintenance.
