where there is no power supply, alternatives are required. Even small wind turbines are now quite powerful.
Where the wind blows, electricity can be harvested: This simple formula, underlying the development of wind generators, falls to owners of secluded cottages, Arbors or caravans quickly, when they are looking for alternatives to the public power supply.
Before we can start, However, you should ask the municipality or the administration of the holiday complex about legal regulations and inform your neighbors.
The next step is planning as needed: Wind turbines consist of just a few components and can be put together individually. A powerful plant (without 220 V connection option) is already off 1400 to have DM. Mini wind power plants are now completely safe and reliable. They completed their development probationary period on the high seas. Because small wind turbines and generators have been used on sailing ships for around 15 Used under tough conditions for years, to permanently charge the on-board batteries.
Result mind modern Generator, even in relatively unfavorable locations and with little wind (wind force from 2 to 3) produce electricity, because the sophisticated, smooth-running rotors directly – without going through a gearbox – connected to the generator.
Building blocks for the wind turbine
Rotor, Mast and generator are the most important components of a system, but not the only ones. An electronic controller is also necessary (ab ca. 80 EUR), which stops the supply of charging current to the battery, if those (with. B. after a windy day) is fully charged.
A battery as power storage must be natural. Solar gel batteries are suitable (no car batteries!), which absorb even the smallest charging currents and also run out- and (largely) are safe from deep discharge. Preis: that. 300 EUR. Usually only allowed 12- or 24-volt consumers are supplied by the battery. But an inverter is connected downstream, you can even connect 220 volt devices. For devices up to 600 Watt cost is approx. 400 EUR.
Of course, when there is absolutely no wind, no electricity is produced, and when permanent consumers are connected, the battery will of course run out quickly. Does that happen more often?, This greatly shortens the service life of the power storage. The antidote: an additional deep discharge protection, which prevents the battery from being completely drained. Preis: ab ca. 60 EUR. Wind turbines are designed by the manufacturers to be hurricane-proof. On the other hand, the operator alone is responsible for the stability on site. That means: The mast should be 100% secured with ground anchors and wire ropes. In addition, the rotor must be mounted so high, that it is unattainable under normal conditions.
Finally, all live parts must be carefully insulated and protected – so that the joy of the power from the air is undiminished.
