The automatic electrical N/S sources switcher, is build using a PIC16F877A micro-controller and electrical input/output sensors. This system is programmed in C language using the MikroC compiler. It's accurate, smart, flexible and easily configurable. It is designed to automatically get instantaneous measurements of the currents; Voltages delivered by three sources of energy, also the levels of photovoltaic batteries, the level of diesel and, also temperature inside and outside of the server room. And to deduct the consummate power and the power factor from it.  And to switch towards the suitable source of energy according to the parameters configured in its program. The measurements are collected with repetitions rate tuneable from one to sixty minutes, are archived in an application especially developed for this system, and displayed on a LCD central monitor. The processing of these information’s relating to the instructions configured by the operator, allowed to connect with efficiency the Data center, on one of the three source of electrical energy: Normal source ONE (Moroccan electricity provider), first Emergency photo-voltaic source, and the generating diesel source.
