An inverter is a special electrical device used to convert a direct current into an alternating current.
The efficiency of a photovoltaic system depends on the efficiency of the inverter. The first to use the word inverter in the field of electrical engineering was David Chandler Prince who in 1925 published an article in the magazine The General Electric Review, in which he illustrated the operation of this device. Its task, in fact, is to transform direct current into single-phase and multiphase alternating current.
In the photovoltaic field, the inverter transforms the direct current produced by the solar cells into alternating current suitable for the grid. Its quality determines the efficiency and therefore is the heart of every photovoltaic system and can be mounted both indoors and outdoors.
