La importancia de los inversores de señal en la generación de energía fotovoltaica

Abstract

A manual was created for Growatt brand investors, which lists all the features and complementary equipment that help carry out a solar energy installation. The work took into account protection against atmospheric discharges, overloads and short circuit, which play a very important role in the system, since they are responsible for protecting the inverters and internal installations, especially the inverters since they are equipment that can be very sensitive to high instantaneous currents. Throughout the internship, several of the related equipment was also met, especially the OFF GRID SPF since due to misuse by some clients they exceeded their capacities causing damage to their control cards and powers, the internal components could be seen in its power electronics, understanding each function of the cards and semiconductor devices, where on several occasions only by changing the cards it was possible to provide a solution and fix the equipment, while with the ON GRID type inverters no warranty cases were evident. Due to its way of feeding the loads with the help of the grid, helping to prevent the inverters from exceeding their nominal power capacity, which is a great advantage for this type of inverters. When carrying out an ON GRID type project from the beginning, it was possible to carry out the step by step that was related in the document, where each step had to be reviewed repeatedly to avoid non-conformity on the part of the network operator, the process lasts considerable time and must clarify this for clients; since they are long times and are subject to corrections, which becomes a complex process, because each new project may vary due to the conditions of the place, since being very old installations, changes may be required in the energy measurement boxes. , increasing the procedures, time and expenses on the part of the company that requires the photovoltaic generation system. The use of AutoCAD and the Microsoft Office package were constantly used throughout the internship, for project calculations and diagrams that helped to understand a little more about the different insolations, as well as the one-line diagrams required by the operator for ON projects. GRID, where you must be very clear with all the equipment that is going to be used, such as protections, conductors, pipes, panels and boxes. Finally, knowing the people who are approved to execute, direct and approve photovoltaic generation projects, where you must have the title of electrical engineer with a professional card and certifications that specify that, if there is knowledge in solar energy, It is important to have these requirements in order to validate the projects.
