Microinverter-based Grid-connected PV System System Introduction The microinverter-based grid-connected PV system is mainly composed of the PV modules, grid-connected PV microinverter ("microinverter"), monitoring platform, and power grid. The system structure is shown below. figure 2-1 Microinverter-based Grid-connected PV System Microinverter As an integral part of the PV power system, the microinverter converts the DC power gener- ated from the PV modules into the grid-compatible AC power and feeds it to the grid.

For more information, please refer to iSolarCloud (Web) User Manual. iSolarCloud App The iSolarCloud App is a mobile application designed for new energy power plant manage- ment.
Microinverter Types of Microinverters Based on the number of PV modules that can be connected, the microinverters are divided into two types: “1-in-1” and “2-in-1”. Only one PV module can be connected to an "1-in-1" mi- croinverter, while two to a "2-in-1" microinverter, as shown in the figure below. figure 3-1 Types of Microinverters Features •...
Balcony PV System In balcony PV systems, the use of microinverters can help to increase the yield. The product intended for this scenario comes with a cable with a wall plug. Users can put the wall plug in- to the wall socket to power the microinverter. As complicated wiring is not required, the in- stallation is made easier, as shown in the figure below.
