A new operation and maintenance tool has been added to speed up the commissioning process of PVH's photovoltaic controllers: Near Field Communication (NFC). NFC is a contactless communication technology, with which PVH performs the commissioning of each of the DBox controllers. In this way, it is enough to download the mobile app of the company and bring the Smartphone closer to the sensor of the controller. At that moment, the commissioning team, and later, the maintenance personnel, will be able to access all the necessary information without opening the box, which is a guarantee of durability and maintenance, since the components will not be exposed to humidity, rain, or dust. Another advantage offered by NFC is that it allows plant operators and maintenance personnel to know the state of charge of the batteries and/or the string current; to change the inclinometers; to detect a possible failure in the solar tracker; and even to load the operating parameters, among others.
