How does a small wind energy system work?
The key feature of a small wind energy system is the wind turbine. The turbine uses the energy of motion (ki-netic energy) from the wind to turn a shaft, thus making mechanical energy. This shaft is attached to a generator. The resulting spin within the genera-tor makes electricity. A wind turbine thus operates the opposite way of a fan.
Can a small wind energy system be connected to a larger grid?
Nearly all small wind energy systems installed today are (or can be) safely connected to the larger power grid. This allows you to take electricity from the grid when your system cannot supply all your power needs, or to possibly supply excess power to the grid, typically earning wholesale rates for excess power.
What is a small-scale wind conversion system?
A small-scale wind conversion system integrates a full-scale power electronic converter between the wind turbine generator and the load. This setup provides extra technical performance.
What is a stand-alone wind power system?
A small-scale stand-alone wind power system is common and essential for providing stable and reliable electricity in rural and remote areas. This system uses a battery bank as the energy storage component, with the load being the battery itself, which can be considered as an energy sink with almost constant voltage.
What is a small-scale wind turbine?
A small-scale wind turbine consists of a generator, a power electronic converter, and a control system. Among different types of small-size wind turbine, permanent magnet (PM) generator is widely used because of its high reliability and simple structure [1, 2]
What is a grid connected small wind generating system?
A grid-connected small wind generating system is a system that feeds excess energy from the wind generator to the utility grid. This type of system, without battery storage, is increasingly popular among homeowners and small businesses in rural areas. The AC grid can also be a diesel grid or a battery/diesel mini hybrid grid.

The main difference is the size of loads you need to run. Running a couple of 15a(AC) 120v loads means > 300a(DC) on a 12v system, requiring heavy wire etc., which gets pretty impractical. Running on a 48v system the same loads would be 1/4 the amps, so ~75adc. A 12v system would also require 4x the charge controller capacity.
