A photovoltaic inverter transforms the energy of direct current from photovoltaic generator in alternating current. Photovoltaic inverters have two subdivisions that are: isolated inverters and inverters connected to the network. As of today, 2022, in Spain, practically all the inverters that are installed are inverters connected to the grid. Therefore, in this article we will talk about such investors.
According to the number of phases, inverters can be classified in different ways between inverters single-phase and three-phase . They are also usually classified with respect to the system configuration in the following: central inverters, chain inverters (string) and modular inverters (AC modules). Also, with respect to the number of stages, they can be distributed among single-stage, two-stage and multi-stage inverters.
