Grid-tied solar inverters, also known as grid-connected inverters or on-grid inverters, are a type of power conversion device used in photovoltaic (PV) systems. They are specifically designed to convert the direct current (DC) generated by solar panels into alternating current (AC) that can be fed directly into the electrical grid.

Grid-tied solar inverters are widely used in residential, commercial, and utility-scale solar installations. They enable homeowners, businesses, and solar farms to generate their own electricity and reduce their reliance on traditional power sources. By feeding excess energy back into the grid, grid-tied systems contribute to the overall energy supply and help promote renewable energy integration.

It's important to note that grid-tied solar inverters require a stable and operational grid connection to function. During a grid outage, they automatically disconnect from the grid for safety reasons and do not provide power to the premises. For backup power during outages, additional equipment such as batteries and backup inverters may be required in a hybrid or off-grid configuration.
