Green Collar Careers - Wind
Turbine Grid and Off Grid Applications
for Grid Tied for wind turbines are much the same as for
Solar PV Grid Tie
systems. The utility will still need to approve the system
including the inverter, grounding, and disconnects.
to identify inverters approved for the utility your
customer is using, search through the
Database of State
Incentives and Renewable Energy and find the utility service.
There should be a link to their requirements for Grid Tied systems.
A few utilities may not have qualified any wind turbines for grid
tied connection so be sure to check with them in advance.
|Off Grid wind turbines
have several possible configurations.
Initial applications for wind turbines have typically been
off-grid to power pumps for irrigation and livestock water
supplies. This lead to the development of 24 VDC brush type
generators. Generators were connected to a Charge Controller
that limited the level of charge voltage supplied to batteries.
As residential power supply began to grow many
of the DC wind turbines have been used for both Grid Tied and Off
-Grid applications. DC generator systems do not offer the
performance of modern AC systems.
For an Off Grid application a DC Generator will be the lowest cost
system to purchase, and for many applications the DC system will offer
a lower cost alternative to solar as well.
