AB Grid-connected photovoltaic (PV) systems are designed to provide energy to the grid. Thisenergy transfer must fulfil some requirements such as system stability, power quality and reliability.Thus, the aim of this work is to design and control a grid-connected PV system via wireless toguarantee the correct operation of the system. It is crucial to monitor and supervise the system tocontrol and/or detect faults in real time and in a remote way. To do that, the DC/DC converter andthe DC/AC converter of the grid-connected PV system are controlled wirelessly, reducing costs incabling installations. The used control methods are the sliding for the DC/DC converter and theProportional-Integral (PI) for the inverter. The sliding control is robust, ensures system stabilityunder perturbations, and is proven to work well via wireless. The PI control is simple and effective,proving its validity through wireless too. In addition, the effect of the communications is analysed inboth controllers. An experimental platform has been built to conduct the experiments to verify theoperation of the grid-connected PV system remotely. The results show that the system operates well,achieving the desired values for the maximum power point tracker (MPPT) sliding control and theenergy transfer from the inverter to the grid.
