Dyna-Living Wind Turbine Generator Kit 400W 24V with 3 Blade,Wind Generator Kit with Charge Controller for Home, Boat or Industrial Energy

At first look it appears to be fairly sturdy but having viewed many you tube vids showing the internal construction its clear that the business parts are very cheap and nasty. The stator is very loosely wound with poor symmetry and the permanent magnets on the rotor are absolutely tiny. This thing wouldn't produce 500w in a hurricane. The most mine has produced is around 50 watts and I live in a particularly windy location. Chinese manufactures have no regard for consumer law and continue to offload sub standard products in the UK and appear to be getting away with it every time.

Bit of a black art, these wind generators! Bought one of these mid-September & not had much charging current from it at all. Paid to have a proper support pole made up with a matching flange welded to it. Ran a 3 phase, steel armoured cable from junction box mounted on pole & tried connecting to two different controllers connected to 12 Volt Lead-Acid battery. Also tried a separate 3 phase rectifier with 30,000uF capacitor to charge battery. Had voltages up to 70 Volts DC without a load on the bench! (See below) None of this really seemed to work very well, although limited power was obtained intermittently when the wind blew. Wondered if the item was faulty, so opened it up, undoing the four hex-headed screws on front plate. Very little to go wrong inside. The basic mechanical construction seemed sound enough, but the actual 'alternator' to generate 3 phase (delta) AC was a little unsubstantial. The rotor connected to the main shaft had a lot of small bar magnets on it, and the stator consisted of coils wound with about 20 gauge enamelled wire. Copper slip rings at the back allow for continuing power transfer when the body swivels around in the wind. Disappointed, I decided to test it out on the work bench with an electric drill to spin the shaft with the blades removed. Also had some appropriate test equipment to take measurements on the output. Succeeded in obtaining some power into the charge controller and 3.2 Amps charging current (measured on AVO8 & DVM etc) into the leisure battery with the drill rotating quite fast - actual speed of rotation unknown. Could have looked at the AC with a scope & possibly frequency counter to work out the rotation, but didn't, & anyway, it seemed to be working for a 12 Volt setup in a limited fashion.Overall conclusions:- Rather quirky. There hasn't been enough wind so far, this Autumn. The mounting pole is probably too low - a taller pole required in a better, more windy location. The 3 phase cable run between the pole & controller may be too long, although the DC resistance was about 0.1 Ohm. Doubt whether this item would work very well with a 24 Volt system. Will keep experimenting to try and improve the situation, but it looks like the blades would need to be rotating in a gale force wind to generate consistently useful charging for a battery, and that would only be rather low current. Suspect best configuration may be to connect the charge controller supplied, as close as possible to the wind generator on its pole & run the DC with thick low voltage cables to the battery.

The media could not be loaded.  First thing is I do not have my turbine in the most optimal location and i suspect most of the ones that posted negative reviews don't either. I have mine about 6m off the ground in an area surrounded by other houses and some trees. (With one relatively clear area in the East as in the pic and the winds never blown from that direction yet). Nonetheless i am able to get over 100wh daily one time over 300wh which is sufficient to suppliment my solar and charge a couple 100ah leisure batteries. So far max I have seen was 120w. I have no doubt if you could ger it 60feet in the air with clean winds you can get 1kw+ per day on a windy day with it as it would be spinning much more consistently and probably might see 400watts. This is because it does have to be spinning quite fast and in turbulent wind that doesn't happen as consistent as you would hope.For anyone wondering the mast i used is 57mm though i think you can get away with 54-57mm.

This wasnt a cheap item and i have a lot of wind where i live and it only just turns so it produces well less than the 500 watts as stated if it turned in the wind all day it may produce 150 watts

I bought this and had a pole made for it at some cost. In a 50 mph wind the vibration was felt through our cabin and yet only 2 amps at 23 volts was produced meaning it cannot charge a 24 volt battery system and is not the 500 watts claimed. Save your money.

Erected this 400w wind generator on a 30ft pole the maximum power it has produced set up 24v was 0.2amp (5W)set up 12v was 1.4amp (15w)these measurements were read during two windy storms. 400W my ass.

Poor construction. Loose fittings

Even in very strong winds, I have been lucky to get around 28 watts despite the blades turning at really fast speeds.
