With an increase of the investments on grid-connected PV systems, a pursue for solutions to assure the stability and reliability of the technologies applied is under way. In order to limit or even control the thermal damage caused by overheat on PV Inverters, different approaches to their control have been tested and implemented, using different parameters to guide Constant Power Generation (CPG). This project presents a comparative approach between three major strategies to implement it, using as a measure the energy cost of different setups in selected scenarios, and then checked with their Lifetime Consumption (LC) reduction.
