In this paper, a photovoltaic (PV) system, with maximum power point tracking (MPPT) connected to a differential inverter is presented. The main characteristic of the used inverter is its potential ability to adapt to the permanent variation of the incident solar irradiation intensity that consequently imposes variable electrical quantities at the output of the PV panels, whereas our devices function with fixed electrical quantities. This set of related algorithms will identify the suitable duty ratio in which the DC/DC converter should be operated to maximize the power output, and suitable duty ratio in which the DC/DC/AC converter works according to the reference output signal. Results showed that this inverter is able to reach the output voltage reference despite the input voltage variation. \textcopyright Springer Nature Singapore Pte Ltd. 2021.
