太阳能发电用逆变电源的工程师指南
以可再生能源为基础的家庭能源系统，如太阳能和风能，正越来越受到消费者的欢迎，并将得到政府机构越来越多的支持。
在这篇文章中，电源逆变器将太阳能的背景下进行讨论，特别是因为它涉及到最新的低功耗微逆变器的架构，将光伏（PV）面板的最有意义的直流输出的交流信号作住宅用途。
微逆变器安装在每个光伏面板和一般处理300 W微逆变器提供给那些想要开始小的可扩展性的好处，但有全DC / AC转换的最大功率点跟踪（MPPT）。许多人希望把多余的电力重新投入电网，这将加快投资回报（ROI）时间，并最终可以从电网依赖中解脱出来。这种技术将使我们屋顶上无处不在的建筑越来越接近。
Microinverters maximize the power collected from every panel and are not affected by a parTIcular solar panel performing poorly. String inverters will be restricted to the actual power produced by the least effecTIve solar panel within a string. If a single panel is dusty， defecTIve， aligned differently， or a different model of solar panel， etc.， it drags down an enTIre string. A microinverter’s individualized solar panel harvest will supply somewhere between a 5 percent and 25 percent increase in electricity output when compared to a string inverter configuration.
Solid-state inverters have been shown to be the enabling technology for putting PV systems onto the grid. A cost reduction per inverter Watt is， therefore， important to make PV-generated power more attractive （Figure 1）。
