Inverter is essential component in grid connected PV systems. This review focus on the standards of inverter for grid connected PV system, several inverter topologies for connecting PV panels to the three phase or single phase grid with their advantages and limitations.
In addition, various inverter topologies i.e. power de-coupling, single stage inverter, multiple stage inverter, transformer and transformerless inverters, multilevel inverters, and soft switching inverters are investigated. It is also discussed that the DC-link capacitor of the inverter is a limiting factor.
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.
In solar PV systems, several two stage power converters and inverter fed transformer topologies are used, as discussed here. Additionally, there are single stage topologies existing in the literature that can offer more efficiency for specific configurations.
