A high-level block diagram of a grid-connected solar microinverter system is shown in Figure 4. The term, “microinverter”, refers to a solar PV system comprised of a single low-power inverter module for each PV panel.
The term, “microinverter”, refers to a solar PV system comprised of a single low-power inverter module for each PV panel. These systems are becoming more and more popular as they reduce overall installation costs, improve safety and better maximize the solar energy harvest. Other advantages of a solar microinverter system include:
In single phase grid connected photovoltaic power systems, the concept of micro inverter has become a future trend for its removal of energy yield mismatches among PV modules, possibility of individual PV module-oriented optimal design, independent maximum power point tracking, and “plug and play” concept.
The Solar Microinverter Reference Design is a single stage, grid-connected, solar PV microinverter. This means that the DC power from the solar panel is converted directly to a rectified AC signal. This con-version is done by an interleaved flyback converter.
