There are different inverter topologies used for single phase or three phase grid connected PV systems like central inverter, string inverter, multi-string inverter, and module integrated microinverter according to their architecture or arrangement of PV modules interface with inverter and grid.
Power Topology Considerations for Solar String Inverters and Energy Storage Systems (Rev. A) As PV solar installations continue to grow rapidly over the last decade, the need for solar inverters with high efficiency, improved power density and higher power handling capabilities continue to increase.
In general, on the basis of transformer, the grid-connected PV inverter topologies are categorized into two groups, i.e., those with transformer and the ones which are transformerless. Line-frequency transformers are used in the inverters for galvanic isolation of between the PV panel and the utility grid.
