As its name suggests, a micro inverter is a small solar inverter used to convert DC power coming from one solar PV Module panel to AC power. It is placed directly at the back of the solar panel and its typical rated power is between 180-500W.
Micro inverters have a number of advantages over their larger counterparts. First, because they are placed directly at the panel, they can optimize the power output of each individual panel, which is not possible with a centralized inverter. Second, they are much easier to install and maintain, since there is no need to run long DC wires from the panels to the inverter. Finally, they are much more resistant to faults, since a single panel can continue to produce power even if one or more other panels are not functioning properly.
Overall, micro inverters are a great option for those looking to get the most out of their solar PV system.
