AB  - A prototype automatic transfer system was designed and implemented with the purpose of initiating
and encouraging the manufacture of automatic or semi-automatic equipment of this type for the electrical
industry in the region. This system performs the commutation by means of two three-phase electromagnetic
contactors between a photovoltaic solar energy system and the public electricity grid using a Raspberry Pi 3B
card as a logical processing module, the programming of the card was carried out by means of the programming
language of high level Python. Through the developer Framework7, an interface was implemented that allows
the visualization of the operating parameters remotely, since, different factors of the system can be monitored
voltage levels per phase, frequency per phase and the current work network from a device with iOS or Android
operating system. Also, the interface generates notifications when the work network is switched, even while
running in the background. The measured data are sent and linked to the interface in real time using Google’s
mobile platform, firebase, through a wireless internet connection, although, you also have the option of making
it wired. With this prototype, we can achieve an introduction to a research and labor field little explored in our
region, since, we have an option at a moderate cost, simple and with a view to interesting improvements for
possible commercialization.
