What is a grid-connected PV system?
Block diagram of the grid-connected PV system's inverter control system. An essential component of grids-connected PV systems, the DC-AC inverter transforms the DC electricity from PV arrays into AC power that is compatible with the utility grid.
Does the photovoltaic grid-connected inverter consume electricity
Since grid tied photovoltaic systems feed their solar generated electricity directly back into the utility grid when not needed for self-consumption. Expensive back-up batteries are not necessary and can therefore be omitted from most grid connected designs. It's a device that converts direct current (DC) electricity, which is what a solar panel generates, to alternating current (AC) electricity, which the electrical grid uses. Modern inverters monitor grid conditions in real-time for safe power export. Anti-islanding protection prevents backfeeding during outages. Unlike off-grid inverters, On-Grid inverters. . [pdf]
