›Solar grid-connected Inverter Grid-connected PV inverter designed to be inter-connected to the electric utility grid. An inverter is an electrical device that converts direct current (DC) to alternating current (AC); the converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits.
