Grid connection standards for inverters

Q: What is a grid-connected inverter?

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.
