MPP is the PV output voltage at which the PV module delivers maximum energy to load. Interfacing a solar microinverter module with the power grid involves two major tasks. One is to ensure that the solar microinverter module is operated at the Maximum Power Point (MPP). The second is to inject a sinusoidal current into the grid.
Solar microinverters must guarantee that the PV mod-ule is operated at the MPP, to capture maximum energy from the PV module. This is accomplished by the max-imum power point control loop known as the Maximum Power Point Tracker (MPPT).
The main specification of the grid-connected solar microinverter is that current must be drawn from the PV panel and delivered to the utility grid at unity power factor. eJ*. Based on this, VAC is then calculated, as shown in Equation 9.
Connect one of the wires (Phase/Neutral) con-necting to grid and inverter output. The direction of the current probe should be current flowing to the grid. Remove any covers from the PV panel. The input of the solar microinverter voltage should be equal to the expected PV output voltage.
Figure 8. In a micro solar inverter, we need auxiliary power that can output multiple voltages to A/D sample circuits, drive circuits, MCU controller, and so forth. On the other hand, the auxiliary power must be completely isolated from primary side to secondary side.
