Off Grid Wind Turbine Update

Two-Wind-TurbinesWell, I am proud to announce I finally got the big turbine up in the air and working. A neighbour came over and gave me a hand to raise the wind turbine tower. It wasn’t super heavy, but with two people it made it a lot easier. What also helped was securing a winch and a pulley to a tree next to the guest cabin roof. The extra height really helped to raise the tower and keep the tower pipe from bending.
The only set back was the tower is not as high as I wanted. A 40 foot tall tower would be ideal, but I’m having a hard time sourcing long water pipe. The metal scrappers in my area are snapping up all the metal for recycling. I did find a 30-foot clothes line pole on Craigslist but getting it home and then to the cabin would be an ordeal. I could see it striking another car if it was strapped to the roof of my car. The “experts” claim that the best, undisturbed wind, is 20 feel about the tree line. The trees in around the cabin are called Lodgepole Pine. Very tall and skinny tree with the average height of 36 feet. My only hope is to build a platform up in a tree and then erect a wind turbine mount on it. A hard task, since I’m a little afraid of certain heights. Never used to be like that… something must have happened when I turned 40.

Yep, that’s a 30′ Large Dog Tie-Out Cable Leash. Handy to have, especially with the two snaps at the end. Rated for 1700 lbs


Lots of support for the tower pole and PMA head unit


The seat cushion keeps the blades from being damaged.


A come-a-long was wrapped around a tree and the DC power winch was hooked up to it.

Cable for come-a-long is at the top. Just underneath is the pulley. It worked as a safety and pull up the slack. If there was a problem with the winch. I could tie off the yellow rope below.

Picked up a Sunforce/Coleman 600 Watt 3 Phase Charger Controller from eBay. The controller is MPPT, 12 or 24 volts, rated for 600 watts, has AC hook up and an optional DC hook up for a solar panel or wind turbine and a brake switch. It was part of a $700 wind turbine kit that included a wind turbine, meter and charge controller. The seller said his tower had collapsed and he was selling off the components separately.
Watt-Meter-hook-upBefore raising the tower, all the wire were connected and fuses installed for safety. Sorry, don’t have any exciting amps/voltage numbers to share. I’m still messing around with the proper hook up to the wattmeter. I hooked it up wrong and it displayed the wattage the equipment is consuming, not producing.
Did manage to hook up the charge controller/brake mechanism. I’m curious to see how it works out over the gusty winter months.


Base-of-towerThe wind turbine is located in the same spot as the previous smaller wind turbine. It’s close to the battery bank and out of harms way from people traffic. As mentioned before, I wish it was a lot higher, but that will come in time. Made a nifty mount to the side of the guest cabin for the tower pole. Since this type of wind turbine and blades generates a lot of vibration, I didn’t want it touching, but still wanted a snug fit. Found an old tube from a portable generator and inserted it between the pole and the wood brace. Then, with a bicycle pump, put about 10 lbs of air in the tube. It inflated and filled in the void. Should provide a nice tight fit and minimal vibration.
Take a peek at my base, used 4 hockey pucks to suck up some of the vibration. Works pretty well!
