How to Connect a Wind Generator to a Home

Bring the power of wind energy home by connecting a wind generator to your home. There are different ways to connect depending on a user's needs. The energy generated by wind systems is direct current (DC) electricity. Most household appliances run on alternating current (AC) electricity, so an inverter is needed to change DC to AC. Read on to learn how to connect a wind generator to a home.

  1. Decide what elements of a wind system the household needs. Grid connect systems have the electricity grid as a backup power source, so they can get extra energy from the grid or sell power to the utility. Stand alone systems provide backup power sources through batteries and generators. Any combination of these two systems can be used to suit your needs.

  2. Size the battery system to be able to meet the generating needs of the sight and the usage needs of the household for about three days. The batteries will store excess energy for use on days with little wind. Use deep cycle batteries. These can be recharged over and over without losing capacity.

  3. Install an additional power source like a diesel generator to provide backup power on days without wind for off grid systems. If the household is on-grid charge batteries with power from the grid.

  4. Install an electronic controller or interface that will automatically operate the wind system. It switches between different components in the system depending on usage and the amount of energy being generated, and ensures the batteries aren't overcharged.

  5. Mount the wind interface and an inverter, to convert the generators DC power to household AC power, on a heat resistant surface with plenty of ventilation.

  6. Connect the three wires and ground wire from the wind turbine to the interface. Then connect the interface and ground to the inverter, and the inverter to the grid.

Warnings

  • Injury or electrocution can result from high voltage from the wind generator or inverter. Wiring and maintenance should be preformed by a qualified and licensed electrician.
  • Consult your local utility company before hooking up your wind turbine to the power lines. There may be safety issues for their personnel from the voltage your system puts on the line.
  • Chemical burns can result from a contact with the sulfuric acid in lead-acid batteries. Use protective gloves and safety glasses when working around batteries. Batteries should be kept away from the living space and out of temperature extremes for safety.
