3.1.4 Inverter
The inverter is the electronic device intended to convert the DC supplied by the PV
array into AC, which is generally used in most consumers’ facilities (Fig. 9.17).
The main characteristic parameters of an inverter are the following:
• Nominal voltage: the voltage that should be applied to the input terminals of the
inverter
