A solar inverter is a device that converts the direct current (DC) generated by solar panels into alternating current (AC) for use in the power grid. As solar panels become increasingly popular, solar inverters play an increasingly important role in our lives. Inverters not only convert the electrical energy produced by solar panels into electricity that households or businesses can use, but also send excess energy back to the grid, thus serving as supplementary power sources for the grid. There are many different types of solar inverters with a variety of specifications and functions to choose from. For example, one can choose between single-phase or three-phase inverters, inverters with battery storage, and inverters with data monitoring and system control functions.
