Bests & Worsts Reviews from Amazon

I bought two of these units and installed properly (see pics). I initially gave these 3 stars. I have dropped them to one after finding the magnet motor on Aliba. It is 100 Watts AC 0-50v depending on wind which these won’t start turning till 15mph sustained wind gusting 33mph. Spent all week spending another $1000 on pole setting these up to 30ft. They just seem like they won’t start turning. I am a state licensed electrician and yes checked to make sure that none of the 3phases are crossed (turbine is AC goes into a the included bridge rectifier). Likewise I found the included controller in China for sale. It is rated for 100 Watts. This is absolutely not a 400 watt turbine. I decided to put a 3/4inch drill on one turbine and spin it up to a simulated 40mph wind. Results? Preciously 100 Watts AC. 10.3 amps @ 13.6 volts DC when connected to a deep cycle, half drained battery. I will be returning. I did build poles to handle 110mph zonal ratings for where I live. As u can see in the pics the wires from the turbine are 18ga. That also screams “100 watt” turbine. So let’s calculate power. A 10 amp battery charger for cars or boats uses about 100 Watts @ 120v from the grid. At 40 mph this turbine does 10amps as measured above. Below 20 mph I show about an amp. In my state power is .12 cents a kwh. So a standard battery charger will use roughly .01 penny per hour. Compared to the turbine. At its max at 40mph wind (simulated by spinning motor with a drill to 3000rpms) we get 10 amps at 13.6 volts. Which translates to the generation of the turbine is .01 penny per hour savings “off the grid”. Again that’s at sustained max speed. That’s about $2.00 a week of energy produced at .12/kWh. Factor in a good concrete form and 30foot pole, wiring labor one is at $1000 for everything done right and to code. So technically it will take 20 years to pay back your investment. A single 100 watt solar panel with a grid tie inverter will give you 10x the savings. Well good luck. Just to be clear this is not a 400 watt turbine as measure using the “CE” standards the Company claims they have certifications for. Doug
