Power Configurations


Wind turbines are available in two electrical configurations: Depending on your preference, you can purchase turbines in a battery back-up configuration or a grid-tie configuration. Each of these options is described below.  Although these are the two main options, our engineers are able to provide custom configurations as well. If this is the case, please do not hesitate to Contact Us.


All of our wind turbines are available in a battery back-up configuration. With battery back-up, the wind turbine produces energy from its generator that passes through a “charge controller” device, which converts the electricity into the proper voltage for charging batteries. This electricity is stored in the batteries where it can be used for nearly any application with the addition of an “inverter/charger”.

The principle benefits of a battery back-up system are versatility and the ability to have access to power even during power outages, or if you are in an area where the grid is simply not available. An electrician can wire this system into your home or business so that select appliances like lights, computer servers, and security systems will be powered even when the grid is down.

Furthermore, in the rare instance of prolonged periods of low wind, UGE systems are designed so the grid will automatically back-up the battery, leaving your batteries charged. No matter what, when your neighbors’ power is out, yours will remain on!


Your power stays on thanks to the UGE hybrid system.


Battery Back Up: Grid Failure


The other main option to consider is a grid-tie configuration. Currently, our eddy GT, UGE-4K and UGE-9M models are available in a grid-tie configuration. In a grid-tie system, your wind turbine works with the grid to make sure that your home or business always has enough electricity. When your wind system produces more than you need, you automatically sell the excess electricity back to the grid.

Utility companies in most Western countries allow you to sell your excess energy, though you should check with your local UGE Partner to confirm.

Although the grid-tie systems will allow you to forgo batteries, if the grid fails the turbine will shut down as well. In other words, when your neighbor’s lights are out, yours are too.


Now that you understand the basics, let’s review the trade-offs: A battery back-up configuration turns your wind turbine into a generator as well as a means of renewable energy production, so you’ll have power no matter what happens.

A grid tie configuration allows you to sell any unused power back to your utility company (in most places) but you are still subject to power outages.

Both configurations allow you to produce power and use the grid as back-up while you reap the long-term benefits of producing your own clean, free renewable energy.
