Inverter communication mode and application scenario
Serial inverters and energy storage inverters can be equipped with a data collector with a LAN port. The LAN port collector is connected to network devices such as routers through network
Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.
However, the seamless integration of solar energy into the existing electrical grid requires precise synchronization between the solar inverter and the grid itself. Grid synchronization in solar energy is the process of aligning a solar inverter's output with the grid's voltage, frequency, and phase, enabling safe and efficient power transfer.
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.
Emerging and future trends in control strategies for photovoltaic (PV) grid-connected inverters are driven by the need for increased efficiency, grid integration, flexibility, and sustainability.
