BESS 电池储能
缩写：: Battery Energy Storage System
摘要
储能电池系统（LFP 或 NMC），存储光伏电力供无日照时使用。
详细解释
BESS (Battery Energy Storage System) pairs solar panels with batteries to shift generation to evening use, provide backup power, or participate in grid services (frequency regulation, peak shaving). In 2026, lithium iron phosphate (LFP) dominates due to safety, long cycle life (6000+ cycles), and cost ($90-130/kWh residential, $65-95/kWh utility). Major BESS manufacturers: BYD, CATL, EVE, Pylontech (residential); Sungrow, LiSolar, Trina (utility). Common sizes: 5-15 kWh residential, 50-200 kWh C&I, 600-3000 kWh utility containers.
