Microinverter-based Grid-connected PV System

The microinverter-based grid-connected PV system is mainly composed of the PV modules, grid-connected PV microinverter (“microinverter”), communication and data acquisition device (optional), monitoring platform, and power grid. As an integral part of the PV power system, the microinverter converts the DC power generated from the PV modules into the grid-compatible AC power and feeds it to the grid.

Microinverter

The microinverter is a type of solar inverter that can convert the DC power generated from PV modules into the grid-compatible AC power. Compared with central and string inverters, the microinverter has the advantages of high production and great safety performance and is now widely applied in residential and distributed PV systems.

With its built-in Wi-Fi function, the microinverter can access the Internet through a wireless home router and then upload the data generated during its operation to iSolarCloud. Users can log in to the iSolarCloud monitoring platform or iSolarCloud App to check the cloud data.

Grid

The following figure shows the common grid configurations.

To meet the demand of users in different regions, connection to a split-phase grid system is supported for this inverter, as in the following way. Grounding detection function will not be available when the inverter is used in the split-phase grid system.

Microinverter Features

•    Highpower generationefficiency: In the microinverter-based grid-connected PV system, the microinverter guarantees that the PV modules all work at their optimal performance, through independent MPPT control for each module. Since the modules each has an independent MPPT, their power generation performance will not be affected by each other. That is, the decrease in the power generation of a single module, due to shading, orientation, or other factors, will not affect the power generation efficiency of other modules in the system.

•    Great safetyperformance: As themicroinverter has a relatively low DC voltage rating, only tens of volts, the potential fire risk caused by high-voltage DC arcs is eliminated and the safety is further guaranteed.
•    Smarter O&M: Themicroinverter supportsmodule-level operation and maintenance.  Users can locate every one of the PV modules precisely and perform diagnosis of their operating status, which makes O&M easier and smarter.
