Converter

Inverters convert DC power from panels or batteries into AC 230V. The voltage converter will be adapted for the conversion of the battery voltage into a stand-alone site.
The inverter, meanwhile, is needed to convert the DC voltage of the panels and synchronize with the existing mains for self-consumption .

They exist two technologies: Modified sinus converter, they are effective and inexpensive but are not suitable for all the uses because the quality of the produced current is lower than that of the network.
Pure sinusoidal converters (pure sine) are able to produce a voltage of the same quality as that of the public network.
They can be used to power all types of devices including the most sensitive (video, audio and electronic equipment).
