A solar inverter converts DC to AC, making the DC power from solar panels usable for standard household appliances. This DC-to-AC transformation is the core function of any solar power converter. 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. By the end of this comprehensive guide, you'll understand. . This conversion is done by a solar converter, also known as a solar inverter, which transforms DC power into AC electricity.
