摘要： The installation comprises: a DC-generating arrangement formed by electrical generators (PV1 . . . PVn) which are connected in series and located inside a local area, and supply a remote area with a total direct current that is the sum of the current generated by each of the electrical generators (PV 1 . . . PVn); and an auxiliary power supply device (D) which is arranged inside the local area and provides the auxiliary system (E) with a supply voltage in the local area, wherein the auxiliary power supply device (D) is made up of a current-fed power converter (CP) electrically connected in series, respective input terminals (T1, T2), in the DC-generating arrangement between two connection points (p1, p2) of the electrical generators, located inside the local area.
