Hi arc,
Its not connected to a battery at the moment, just went up. Its sitting on a tree (a cheap tower), about 25 ft up, sitting on a bluff, so its a little taller then the trees. If all goes well with my mouting system, I will put up a second TDM up that should be about 40 feet up. No charge controller, just a diode to stop any voltage reversal.
Did some pondering this weekend, and I'm going with your suggestions to setup a 'Battery Shack' below the turbine and then hook-up the rechargeable light. I'm leaning toward an AGM (Advanced Glass Mat) sealed deep cycle battery (about $180 CDN for 55 Amp hours). Probably will go with 1 battery for trial purposes. The Battery Shack will be exposed to -45 Celsius tempartures in the Winter, and from what I have read the AGM batteries are tough in these conditions.
We have Class 2 winds here (Ontario, Ottawa valley), but when it blows, it really lets loose and it goes for a few days.
Thanks for your response,
Rob
