- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
Things You Will Need
- Wind generator
- Power interface or controller
- Power inverter
- Don't use automotive batteries in a wind system. They are not made to be drained and recharged again and again.
- Save money by being more efficient with a household's energy use, and reduce the size of the wind system needed.
