AB The design, monitoring, and control of photovoltaic (PV) systems are complex tasks thatare often handled together, and they are made even more difficult by introducing features suchas real-time, sensor-based operation, wireless communication, and multiple sensor nodes. Thispaper proposes an integrated approach to handle these tasks, in order to achieve a system efficientin tracking the maximum power and injecting the energy from the PV modules to the grid in thecorrect way. Control is performed by means of an adaptive Lyapunov maximum power pointtracking (MPPT) algorithm for the DC/DC converters and a proportional integral (PI) control forthe inverters, which are applied to the system using low latency wireless technology. The systemsolution exploits a low-cost wireless multi-sensor architecture installed in each DC/DC converterand in each inverter and equipped with voltage, current, irradiance, and temperature sensors. Ahost node provides effective control, management, and coordination of two relatively independentwireless sensor systems. Experimental validation shows that the controllers ensure maximum powertransfer to the grid, injecting low harmonic distortion current, thus guaranteeing the robustnessand stability of the system. The results verified that the MPPT efficiency is over 99%, even underperturbations and using wireless communication. Moreover, the converters’ efficiency remains high,i.e., for the DC/DC converter a mean value of 95.5% and for the inverter 93.3%.
