The inverter is a device that allows you to convert direct current received from solar panels to alternating current.
The direct current generated by the photovoltaic installation can be used without conversion, however, in practice, most electrical appliances and a centralized electrical network use alternating current. That is why the inverter for solar panels is almost indispensable.
