  • These turbines look good but barely generate 10 % of their advertised output. I suspect the included charge controller being connected to the battery uses more power than the turbine can produce in an average month.
    Waste of money, better off with another solar panel.
    I plan to ditch the generator and bolt the blades to my own modified smartdrive permanent magnet generator, should make around 500 watts in a good wind.
    To the trolls assuming my cable is too light and complaining about tree top turbulence, please read the following to put your minds at ease -:
    Turbine has no problem getting up to full speed, infact I find the tree line ramps up and increases wind speed just above the tree tops in this location, sure there is some turbulence but when I see the blades spinning full speed I know its not a major issue. Cable loss is negligible with such a low output from the turbine -my wire gauge 4mm2, cable length 20m, max 20a advertised output from turbine 20a = AC energy loss of 20.78% worst case scenario with advertised output. Now from testing on the bench at recommended rpm with near flat 24v batt as a load, wired through the reg/rec as shown in the manual and experimenting with various loads including a 12v battery I know maximum output is more like 65w which would give me a cable loss of 3.1% not enough to worry about.

ALWAYS THE SAME WITH CHINESE WIND TURBINE. LOOK AT MORE RU-clip AND SEE.

Sir ye kiss market me parchesh hoga kitna price hai

How many form ali.?

If idiots like some of these below do not have USEFUL critiques or comments; DO NOT POST

I’m just a girl who took physics and most people should know from a high school EM that the wire will cause resistance the longer and thicker the wire, the more resistance — you may wish to put the device on your roof closest to your battery storage.

You are correct about the cable resistance, however with such a low output from the turbine, cable loss is minimal, not enough to worry about.

Usually they refer to watt hour per day..That 400 number is ok..

How much us dollar

Pretty white blades,not your fault bro. Just shitty products, I’d demand a refund

sorry Charlie — I seen a crap load of mistakes here. I own 2 400w airex — 1 — can’t use a tree- it moves , blocks wind from some directions. it must be pole mounted away from turbulence and be perfectly plumb since the blades are at 4% off perpendicular to start the rotation at low wind speeds. 2 — the distance from the turbine to batteries is way to far. since its 12v dc, the line loss of 2-3 % is now probably 75-80% or higher. what size wire did you use?? 12 gauge copper? probably. can’t use aluminum in dc. size the wire for the distance. too small wire may cause internal problems leading to self destruction. properly installed — I get 300w per at 15mph winds — 400w at or above 25mph. the unit should already contain a proper charge controller built into the 3 phase alternator . just don’t read the directions — do some investigation into HOW TO PROPERLY INSTALL A WIND TURBINE>

Incorrect on all points. Turbine has no problem getting up to full speed, infact I find the tree line ramps up and increases wind speed just above the tree tops in this location, sure there is some turbulence but when I see the blades spinning full speed I know its not a major issue. My setup is actually 24v, not 12 v as you wrongly assume. As for cable loss, this is negligible with such a low output from the turbine -my wire gauge 4mm2, cable length 20m, max 20a advertised output from turbine 20a = AC energy loss of 20.78% worst case scenario with advertised output. Now from testing on the bench at recommended rpm with near flat 24v batt as a load, wired through the reg/rec as shown in the manual and experimenting with various loads including a 12v battery I know maximum output is more like 65w which would give me a cable loss of 3.1% not enough to worry about. So before you embarrass yourself further, be sure to have all the facts before spouting know-it-all nonsense.
