One method of generating more power with wind turbine systems is tying together multiple wind generators. The principle of connecting the direct current output of multiple wind generators together is similar to that of connecting multiple solar panels together. Doing so 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.
Things You'll Need
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.)
How to Tie Together Multiple Wind Generators
Install a combiner electrical box specifically designed for use with wind energy at a convenient location. Combiner boxes are intended for installations with more than one wind generator and are used to bring together the outputs of multiple generators 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.
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.
Shock Hazard: Before making any electrical connections always ensure power from the grid is turned off. Use a voltmeter to verify that all power is off.
Follow all local code requirements for electrical installations.
Final grid connections should be made by a licensed electrician only.
