    Page 10 of 65 PVI-2000-OUTD-AU Rev.: 1.0) FOREWARD This document contains a technical description of the AURORA photovoltaic inverter so as to provide the installer and user all the necessary information about installation, operation and use of AURORA. PHOTOVOLTAIC ENERGY Industrialised countries (greater energy consumers) have been experimenting with energy-saving methods and reducing pollutant levels.

  • Page 11: System Description

    PVI-2000-OUTD-AU Rev.: 1.0) SYSTEM DESCRIPTION AURORA is an inverter that exports energy to the electrical power distribution grid. Photovoltaic panels transform the solar radiation into electrical energy in the form of direct (Dc) current (through a photovoltaic field, also known as PV generator); In order to utilise this energy and feed it back to the distribution grid, this energy shall be turned into alternating (Ac) current.

  • Page 12: Main Elements Of Apv System : "Strings And Arrays

    Larger photovoltaic systems can be composed of a certain number of arrays, connected to one or more AURORA inverters. By maximizing the number of panels in series per string, the cost and complexity of the system wiring can be reduced.
  • Page 13 NOTE: The minimum required input voltage for start the initial grid connection sequence is 200Vdc. When Aurora is connected, it will export energy on the grid since the input range will remain between 90Vdc and 580Vdc. The total current of an array must also be within the capability limits of the inverter.

  • Page 14: Data Transmission And Check

    AURORA Technical Description Figure 4 shows the AURORA block diagram. The main blocks are given by the input Dc-Dc converters (also known as “booster”) and the output inverter. Both the Dc-Dc converters and the output inverter work at high switching frequency to minimize size and weight.
  • Page 15 AURORA operative system communicates with the relative components to carry out data analysis. All this guarantees an optimal operation of the whole system and a very high performance in every insulation and load situation, always in compliance with the relative standards and regulations.
