Power inverters are key electronic components in solar power systems. In commercial applications, these components connect photovoltaic (PV) panels, batteries that store electrical energy, and the local power distribution system or utility grid.

In a typical solar harvesting system, multiple solar panels are connected in parallel to an inverter that converts the variable DC output from multiple PV cells into a clean 50Hz or 60Hz sine wave inverter power.

The primary design goal is to maximize conversion efficiency. This is a complex and iterative process that involves maximum power point tracking algorithms (MPPT) and real-time controllers that execute the associated algorithms.
