You will need more sustained wind than 5-8 mph (minimum double or 12-15 mph for a few watts) and a wind turbine with large blades and clear foreground of 100+ yards and a minimum tower height of 50+ feet, otherwise, the physics of wind won't have enough power to turn your blades to turn your alternator to produce current to travel to your charge controller and into your battery. Lots of variables that you have not considered. Generally, unless conditions and the site of the wind turbine are perfect and you have lots of money, wind is not viable or reliable. Gusts are too short, one needs CONSTANT wind energy, hour after hour after hour after hour. Kind of like solar production with lots of clouds but some sun actually doesn't produce much power unlike CONSTANT sun hour after hour after hour after hour.
I have a solar system and a wind turbine, but it's been calm for a week and the skies have been dark overcast and snowing. Therefore, I've had to supplement the low solar production with my gasoline generator. Some days / weeks are like that. Micro hydro would be the only constant power source IF all conditions for it were optimal.

What is the diameter of that turbin blade set?Years ago when I was racing I had a wind turbine that was strapped to the inside of my trailer for the race car, it was under 24' tall. I had welded a "flag pole" on the back bumper of the motor home and when I got to the track for the weekend I would put up the wind turbine. Nothing solar. It was easy to find me in the paddock all you needed to do is look for the wind mill. Typically road racing tracks have lots of nothing around them, so there was ALWAYS a good wind. We could lay in the back at night and hear the windmill start to flutter as it spun too fast, we are sleeping right under it. I had two lead acid batteries strapped to the back of the motorhome for power. (Long before lithium batteries of any kind). We ran everything in the motorhome but the AC off those two batteries and never had power issues. TV Microwave, switched the fridge over. The rates the track charges for electricity are just insane....so the less you could use the better, and some places had rules against running a generator....they say for noise but I think it was to force you to use their power.
In all those years, some "weekends" going for four days we never ran out of power, I never used "shore power" to charge the batteries while there and IIRC it did not take long to charge them when we got home. I know I forgot one weekend and the microwave would not work, so expensive track food, but the fridge and TV worked just fine.....I refused to flip the breaker and use their power for anything but AC....I will eat a crummy $5 burger.
Currently I live basically in the middle of a field, I have played with that old turbine from time to time in the years I had given up racing (health reasons), and wanting to power some of my shop I think it would work.

Ok, that sounds like a decent turbine!I am going to shoot from the hip here, guessing 36"-42", fairly big, and it took 3 of us straining to get it mounted.
About 6 years ago my health went south and it has not seen the light of day. Now getting back on my feet and feeling like doing, and this is something that always interested me. I plan on getting it out this weekend and seeing if it will still work. I have no idea on the brand.
It is big, I remember having to take off two blades to make it fit in the trailer.....a normal 24' enclosed car hauler. When ever we put it up I took so much flack for having bought "the big one". It was a heavy beast.Ok, that sounds like a decent turbine!
Mine are 400W nokacheepies. Useless unless hurricane is here...
