GENERAL INFORMATION AND FEATURES OF A PHOTOVOLTAIC SYSTEM The purpose of this chapter is to provide the user of "AURORA PVI-XXX.0 (-TL)" general information concerning the photovoltaic systems that transform solar energy into electrical energy, usable in the distribution grid.
Installation and Operation Manual Page 19 of 156 [PVI-XXX.0-YY(-TL) - Rev:1.0] 3.2. Fundamental elements of the photovoltaic field: “Strings” and “Arrays” In order to significantly reduce installation costs of the photovoltaic field, especially related to the wiring problem on the inverter DC side and the subsequent distribution on the AC side, the STRING technology was developed.
