MAX20801

MPP跟踪DC-DC转换器

支持PV电池串提供最大整体功率——提高发电量和系统设计灵活性

说明

MAX20801家族电池串优化器支持实现电池串最大功率点跟踪(MPPT),与标准面板及采用模块级MPPT技术的面板相比,拥有优异的光伏(PV)模块能量收集和可靠性。

光伏电池只能在特定电气条件下提供最大功率,而电气条件随照射强度和温度的变化非常显著。串联的PV电池对电池的不匹配非常敏感,造成实际条件下的功率和发电量低于最优值。MAX20801电池串优化器支持PV电池串在较宽范围的负载条件下提供最大整体功率。这种增强的电气灵活性避免了PV组件串和阵列造成的功率损耗,最终提高发电量和系统设计灵活性。

电池串优化器提供的附加独特优势包括:

  • 缓解PV模块使用寿命内的性能下降
  • 避免与旁路二极管导通相关的高损耗
  • 限制PV模块的工作的电压
