Technical FAQs 4

What is a point of interconnection for solar?

Location: The point of interconnection for solar can be at the main service panel (for residential or commercial systems) or at a utility substation (for larger-scale solar farms). Grid Connection: At the POI, the AC power generated by the solar system (after being converted from DC by the inverter) is synchronized with the grid.

What is a grid-connected PV system?

In a grid-connected PV system, the inverter plays a critical role in ensuring high energy conversion efficiency while meeting stringent grid standards for power quality and safety 7.

Can grid-connected PV inverters improve utility grid stability?

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.

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.
