微型逆变器解决方案
微型逆变器在单个光伏 (PV) 电池板上转换电源，单个光伏电池板的额定功率通常为 400W，多个光伏电池板的额定功率则高达 1.5KW。微型逆变器通常基于两级式电源转换。首先，直流转直流阶段或升压电路将可变直流电压转换为固定直流电压（通常为 40 V 到 60 V）。同时，通过最大功率点跟踪技术（MPPT）能较大限度地从光伏板获取能量（通常 FSW = 100 KHz）。
首先在直流转直流阶段或升压电路将可变直流电压转换为固定直流电压（通常为 40 V 到 60 V）。同时，通过最大功率点跟踪（MPPT）技术保证从光伏板中提取最大电流。其次，在直流转交流阶段，逆变级将直流电源转换成与电网兼容的 1Φ 的交流电源。与组串式逆变器相反，微型逆变器可以连接一个、两个或四个光伏板，并分别对每个PV模块进行MPPT跟踪。
