SYSTEM DESCRIPTION

The Aurora inverter feeds a power grid by using the power generated from
photovoltaic panels. The photovoltaic panels transform sun-radiated energy into
electrical energy in the form of direct current (DC) through a photovoltaic field (also
known as a PV generator). In order to utilize this energy and feed it to the distribution
grid, the energy needs to be converted into alternating current (AC). The Aurora
inverter does this conversion, also known as DC to AC inversion, very efficiently
using just static power electronic devices and without the need of rotating parts.
When used in parallel with the power grid, the alternating 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
all the connected user electrical loads, such as lighting devices, household appliances,
etc.
When the photovoltaic system is not generating sufficient energy, the power required
to ensure proper operation of connected user loads is taken from the public power grid.
While, if the produced energy exceeds load needs, it is directly fed to the grid, thus
becoming available to other users' loads.
According to national and local standards and regulations, the user-produced energy
can be sold to the grid or credited to the user against future consumption, thus
reducing costs and providing what could even be significant savings.
