The design of such systems is not covered in this guide, although the notes on cable and fuse sizing are still relevant. Typically, small wind turbine systems will use a lead acid battery bank storage system. Batteries are rated in terms of their voltage and their amp hour (Ah) capacity.
Small wind is a bit of a pain. When in the wind the turbine MUST create energy. So you need a charge controller with a diversion load (some place for the power to go once the batteries are charged). If this is just a school project, you could just use a water heater element to heat water...
The first component to design is the battery bank. A battery bank is an energy store. As the power from the wind will not directly coincide with the power required for the loads, there must be some form of energy storage. This is usually the lead acid battery.
Monitoring the Watt hours or Amp hours on the AC output of the inverter would help record the energy consumed by the loads. As mentioned in the ‘DC load monitoring’ section, monitoring the AC (along with the DC) loads and the energy from the wind turbine would also help the system operator.
As the power from the wind will not directly coincide with the power required for the loads, there must be some form of energy storage. This is usually the lead acid battery. Lead acid batteries use a reversible electro chemical reaction to store energy within an electrolyte.
From the various configurations presented just two are recommended. If the distance from the wind turbine site has to be relatively far then the recommendation is to use the ‘High voltage AC cable, powerhouse near wind turbine’. This is the best mixture of lowest cost and most standard equipment.
In a typical 12V wind turbine system, the wiring diagram will include the following components: the wind turbine itself, which converts the wind''s kinetic energy into electricity; a charge controller, which regulates the flow of electricity from the …
