Solar inverters have one core function: convert the direct current (DC) solar panels generate into an alternating current (AC) used in your home. There are two main types of home solar inverters: Microinverters attach to the back of each panel and are best for complex solar installations.. String inverters connect strings of panels in one central location and are best for simple installations.

Grid-tied solar systems. Grid-tied systems are solar panel installations that are connected to the utility power grid.With a grid-connected system, a home can use the solar energy produced by its solar panels and electricity that comes from the utility grid.. If the solar panels generate more electricity than a home needs, the excess is sent to the grid.
How do Solar Panels Work? – Working of Photovoltaic (PV) Systems
When panels produce excess solar power, the net metering allows it to transport to the utility grid, rewarding energy credit in exchange. It is where the output of the solar inverter gets attached.
