BOS 平衡系统
缩写：: Balance of System
摘要
光伏系统中除组件外的所有部件：逆变器、线缆、支架、汇流箱等。
详细解释
BOS (Balance of System) covers all parts of a solar system other than the modules themselves: inverters, DC/AC wiring, mounting structures, combiner boxes, monitoring systems, transformers, and grid interconnection equipment. For utility-scale projects, BOS represents ~40-50% of total project cost. Reducing BOS cost is a major industry focus. Common BOS optimization: using higher-wattage modules (fewer wires, smaller BOS), single-axis trackers, 1500V or higher system voltage, central inverters.
