Wind Turbine Generator from China

I saw on the news a couple of days ago that China is now the world leader in full size wind turbines.

The info on EBAY seems good, as does the close up pictures of the hardware. After all, its not really high tech anymore, is it.

At that price worth a punt, but remember, no pole or regulator included.

Ive been making a few different versions over the years,, but its cheaper to buy these Chinese ones,and there not too bad either
 
I haven't heard these small turbines in operation but some people claim they are noisy (they probably complain about waves breaking on the beach too). Apparently it is fact that 5 bladed turbines are quieter than 3 bladed so I'll probably g9o down that avenue
 
Have a friend who bought a Chines 3 blade 300w for a shack in the bush. It seemed mechanically well built although after a few years bearings packed up. The biggest problem seemed to be the permanent magnet material. This seemed to lose magnetism such that voltage output fell quite quickly so charge voltage fell dramatically.
The generator was supplied with a magic controller box which turned out to be mostly empty with 6 silicn diodes in it. (3 phase output). I improved the charge capability by replacing the diodes with shotky low volt drop diodes which helped but he never saw anything like the claimed 300watts as battery charge. ie 20 amps. The best he go was about 3 amps. I hear now that the output has diminished further. He mounted the turbine about 30 metres from the house and 8 metres high so no concern on noise.
The original turbine was replaced by the local supplier twice for poor output before my friend gave up and I fitted the low volt drop diodes.
So you take your chances at a low price good luck olewill
Just looking again at the ad. 25 amps at 12.5 volts is what they claim. The generator is presumably self regulating so if your batteries need 14volts to push charge in the max current it will provide at 14 volts will likely be around 5 amps. So you would only get 25 amps if you were using the current say in an inverter type load and not as battery charging. That is their claimed figures then magnet deteriorates. a powered field coil with regulator would be much better.

Is this firm in China? Some of language used on site suggest english as a second language.If so and customs catch you remember there is an extra 23% or thereabouts on the price-vat and duty.Also if they do get you expect a service charge of about £25 as well from couriers.
Small items seem to come into the UK without attracting any attention.
Also I recall looking at a us site importing these items and there is quite a range from smaller more suitable for battery top up to bigger ones.

Can you buy it from Hong Kong?

'HMRC has special arrangements that allow some overseas traders to charge, collect and pay over to us the import VAT for goods purchased by mail order, that would normally be chargeable at the time the goods are imported. These arrangements operate under Memoranda of Understanding (MoU) signed with certain overseas customs and postal authorities. The countries that have a MoU with HMRC are - the Channel Islands, Hong Kong, Singapore and New Zealand. Overseas traders wanting to use this procedure must be authorised to do so by their authorities.
Once authorised, foreign businesses are issued with a unique authorisation number, which they must show on the customs declaration or packaging. They will include the statement 'Import VAT Prepaid'.
Where these arrangements are used you will not be charged a Royal Mail handling fee when you receive your package.'
