6 FAQs about [Selection principles for photovoltaic inverters]

How are PV inverter topologies classified?

The PV inverter topologies are classified based on their connection or arrangement of PV modules as PV system architectures shown in Fig. 3. In the literature, different types of grid-connected PV inverter topologies are available, both single-phase and three-phase, which are as follows:

What is a PV inverter?

An inverter is integrated as an indispensable component to the PV systems in order to convert the DC electricity of the PV module output into AC electricity for the electric grid.

How to choose an inverter for a grid connected PV system?

When specifying an inverter, it is necessary to consider requirements of both the DC input and the AC output. For a grid connected PV system, the DC input power rating of the inverter should be selected to match the PV panel or array.

What are the classifications of PV inverters?

The inverters are categorized into four classifications: 1) the number of power processing stages in cascade; 2) the type of power decoupling between the PV module (s) and the single-phase grid; 3) whether they utilizes a transformer (either line or high frequency) or not; and 4) the type of grid-connected power stage.
