The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.
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.
Efficiency: The selection of a grid-connected PV inverter is mainly based on its efficiency. The inverter must b e capable to attain a high ef ficiency over a wide range of loads. Due to the reduced, and high efficiency is achieved. and disconnect it fro m the grid for safety purposes, while supplying power to the local l oad. In
4. Grid-connected inverter control techniques Although the main function of the grid-connected inverter (GCI) in a PV system is to ensure an efficient DC-AC energy conversion, it must also allow other functions useful to limit the effects of the unpredictable and stochastic nature of the PV source.
