Anyone who’s driven through western Kansas has seen the massive wind turbine fields, called the Smoky Hills Wind Farm — shown in the photos above and below — which uses 56 wind turbines that generate enough energy together to power 37,000 Kansas homes annually. It is a feat of clean energy engineering that is only eclipsed by the Ivanpah Solar Electric Generating System in the California Mojave Desert.
Now, you don’t need to build anything on that large of a scale for your family. Ideally, you’ll want to build something that will be a perfect fit for your individual needs. Something that won’t break the bank, but at the same time will provide you with the power you’ll need to survive.
The first step is, of course, deciding how many 600W Off-grid Wind Turbines you’ll need. You can find this information out largely by taking our Power Shortage challenge and keeping track of your overall usage.
Once you’ve decided this and have purchased the Wind Turbines, you’re ready to start connecting them together. Connecting the direct current output of multiple wind generators together requires wiring the multiple outputs in a parallel electric circuit. The advantage to wiring turbines in parallel is that doing so produces an additive effect. While voltage remains the same the current increases with each additional turbine. In effect it results in the creation of a mini wind farm, so you’ll have your own Smoky Hills in your backyard.
To get started, you’ll need the following:
- Two or more wind generators
- Sufficient RHW-2 10 AWG 1 electrical wire for specific application
- Wind power combiner electrical box assembly
- Electrical hand tools and supplies (pliers, wire strippers, electrical tape, connectors, etc.)
Once you’ve gathered the above tools, follow these steps to build your small wind farm:
- Install a combiner electrical box specifically designed for use with wind energy at a convenient location. You should be able to find these online or in some home improvement shops. You’ll use the combiner boxes to bring together the outputs of the turbines by combining them in a parallel circuit.
- Run electrical wiring from wind generators to the combiner box. Use RHW-2 10 AWG 1 electrical wire as a minimum unless a specific conductor is specified by the wind turbine manufacturer.
- Connect individual positive wires from the wind generators to positive input connections provided in the combiner box. Follow instructions provided with the box by manufacturer.
- Connect individual negative wires from the wind generators to negative input connections provided in the combiner box.
- Finally, connect the positive and negative output side wiring from combination box to the input side of load via a load charge controller with a storage battery installation or to the inverter input side for an on-grid installation application.
