An interactive inverter is designed to both convert DC power from solar panels to AC power and to interact with the electrical grid. One of its essential features is its ability to maximize power output based on grid conditions. This means that when the grid is available, the inverter adjusts its operation to optimize energy transfer and efficiency, ensuring a higher yield from the solar energy system.

The inverter's interaction with the grid allows it to feed excess power generated by the solar panels back into the utility grid, which can help homeowners receive credits or compensation for their contribution to the grid. This capability not only enhances the system's efficiency but also supports the stability of the grid by ensuring that solar power is integrated seamlessly.

While an interactive inverter can operate in conditions with no grid power (which is a feature of some inverters), its primary function revolves around its ability to optimize power output in conjunction with grid conditions, making it a critical component for grid-tied solar energy systems.
