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. AURORA does this conversion, also known as Dc
to Ac inversion, in a very efficient way, without using rotating parts but only static
power electronic devices.
When used in parallel with the grid, the alternate current generated by the inverter is
directly fed to the domestic distribution circuit, which in turn is also connected to the
public power distribution grid.
The solar energy system can thus feed power to all the connected devices, such as
lighting devices, household appliances, etc.
If the energy generated by the photovoltaic system is not enough, the energy necessary
to ensure the standard operation of the connected devices is drawn from the public
power distribution grid. If the energy produced exceeds that used, the difference is
directly fed to the grid, thus becoming available to other users.
According to national and local standards and regulations the produced energy can be
sold to the grid or credited to the user for future consumption.
