For overload protection, the inverters have two main diagrams. The inverter converts only its nominal power, blocking the PV generator from reaching its maximum operating power and/or a shutdown occurs in the event of an overload and only starts operating when the generator has power compatible with the inverter limits (Chen et al., 2013).
The power curve in Fig. 4c shows lower power levels and, consequently, lower inverter temperatures. The maximum temperatures recorded for the three days of the analysis were 70.3 °C, 73.1 °C, and 59.3 °C, which further demonstrates the relationship between the operating power and the temperature at which the DC/AC is submitted.
