Windmill Generator
is there a mini-windmill or mini wind-generator?
i want to get off-grid. we have lots wind on the coast. but the blades i looked at are huge and the poles are way too tall. just a small one in the yard would catch a lot of wind and spin. i only need at least 750 watts, but 1000 watts preferrably. is there a small wind generator or can someone link me to building plans for something like this? some freeplay machines i’ve searched for only make about 50 watts. thank you…
At 1000 watts, it is NOT a mini.
To get 1000 watts at 120V, you need 8 amps.
To get the same watts at 12v you need 80 amps.
THIS is assuming 100% efficiency. (NO conversion is 100% efficient, most are about 60% on smaller systems!)
Therefore you would need to generate aproximately 132 amps at 12v to allow for the losses in conversion to 120V.
NOTE: MOST automobile generators (alternators) only supply 60 amps, and the most common small wind units even less!!
Wind generators need to be a MINIMUM of 20 feet ABOVE any obstructions to wind flow within 100 yards, and HIGHER is BETTER. When you take into account trees, houses, etc. that usually means about 100 feet in the air MINIMUM, AND the unit must be able to withstand the wind forces.
There are many sites which can be found by searching “wind generators” where you can buy generators, parts, find plans etc.

Windmax HY600-3 750 Watt Max 24-Volt 3-Blade Residential Wind Generator Kit $769.00 A wind turbine is a long term investment. Before you purchase a wind turbine, the first factor to consider is if the energy produced by a wind turbine can pay for itself in 10 years or less. The second factor to consider is installation and ownership cost. Poor reliability, low quality and high maintenance will greatly increase ownership cost and make the wind turbine impossible to pay for itself… |
