Grid Tie Inverter
The
Grid Tie Inverter or synchronous inverter is a special type of power inverter
that converts DC electricity into alternating current. A special feature of
these types of inverters is that it can feed AC into the existing electrical
grid. GTIs are often used to convert DC electricity produced by renewable
sources of energy like small wind turbines using permanent magnet generators
into AC used to power homes and businesses.
During
the period of overproduction from the permanent magnet source, power is routed
back to the state grid and hence sold to the local power corporations. But
these types of arrangements are possible with special type of grid networks
only. These grids are specially manufactured to allow ease of distribution and
back feeding. Residential areas and
businesses connected with grid-tied electrical system are permitted in many
countries most popular being North America and Europe. There are different
compensating ways in which different governments pay the individuals for
feeding back the power like “Net metering” or “Feed-in-tariff”.
Due
to this system, the payback period of the renewable energy source like a windpermanent magnet generator decreases and hence the inflow of money is increased
for the consumer. Hence using a wind permanent magnet generator is becoming a
popular way of generating the power in many nations.
