In this blog, we will cover the common types of Grid-Tied or Grid Connected Solar Inverters used in roof-top Solar Power Plants: String Inverters, SolarEdge Optimizer System, and Enphase Micro-inverter System. . An inverter is one of the most important pieces of equipment in a solar energy system. It's a device that converts direct current (DC) electricity, which is what a solar panel generates, to alternating current (AC) electricity, which the electrical grid uses. Considering the classification based on the mode of operation, inverters can be classified into three broad categories: Inverter classification according to Interconnection types is discussed in EME 812. . While solar inverters are the most common type of inverter used for residential solar, they are just one of several inverter options available for solar and energy storage systems.

Grid-connected PV systems enable consumers to contribute unused or excess electricity to the utility grid while using less power from the grid. The application of the system will determine the system's configuration and size. Residential grid-connected PV systems are typically rated at less than 20 kW.
Utility type also affects the architecture of solar PV grid-integrated configuration, whether single phase or three phase. The single-stage and double-stage power processing solar PV integrated configurations are determined by the number of power processing stages involved in each system.
Particularly at high PV penetration levels, PV systems should maintain grid connectivity through reactive power injection in reaction to voltage faults to prevent instigating extreme incidents, such as blackouts. To further reduce the cost of energy, it is necessary to enhance both dependability and efficiency.
The different solar PV configurations, international/ national standards and grid codes for grid connected solar PV systems have been highlighted. The state-of-the-art features of multi-functional grid-connected solar PV inverters for increased penetration of solar PV power are examined.
