A Grid-Tied Inverter is a device that converts direct current (DC) electricity generated by solar panels into alternating current (AC) electricity, which is used in homes and businesses. This type of inverter is connected to the electrical grid, allowing excess energy produced by the solar system to be sent back to the grid. When the solar panels generate more electricity than needed, the Grid-Tied Inverter feeds the surplus power into the grid, often resulting in credits on the electricity bill. This system enhances energy efficiency and supports the use of renewable energy sources like solar power, contributing to a more sustainable energy future.
