I’ve got/had two wind turbines/generators. One is a Rutland & the other a larger unit “made in England” Both of these companies supply spares at a reasonable price.
Like the cheap Chinese generators sold in places like Aldi, these cheap Chinese wind turbines are great while they work, but are either designed/built as disposable commodities or are economically un-repairable.
I’ve no experience with modern/copies/cheap Chinese versions of wind turbines. I would think it’s down to the price/quality of main components used in the manufacturing.
Bearings, resistors etc can be replaced at very little cost, should they fail and (if you can get in to the unit)
I personally prefer solar or a combination.
Yeh sure, they are a good 100 quid cheaper to buy on China’s mainland compared to the UK. I am looking to build a hybrid system for my needs. Solar and wind. 400w wind and 200w solar off grid mobile setup. Solar panels are just as expensive here tho. So buy them back in Blighty. Take a chance whilst here. 👍
Rutland are about the best domestic made unit and easier to deal with if they fail as theyre in the UK if marginally more expensive . Its just not economic to return faulty items to China. Rutland are the default model used on yacht installations so pretty reliable. I think the 'buy cheap buy twice' mantra applies to a lot of Chinese goods. Having bought three defective chinese inverters im not so keen on repeating the time wasting experience.
I had my Rutland stolen off my trailer. I replaced it with an 300w Italian made vertical axis turbine. Even with solar and wind on a pretty windy hillside i needed a genny for occasional use in winter but far superior start up in low wind to conventional fan turbine.
If i was buying another conventional turbine id buy one from the US, such as from Missouri wind and solar. They know how to make very decent turbines at affordable prices if you can tolerate the import duty.
As it is im more impressed with vertical axis turbines and no intention of going back to a conventional fan type any time soon.
Unless you live in an area with pretty regular wind speeds (20 days a month)of above 12 -15 knots youre better off buying more panels and mouting them so you can adjust their angle for the lower winter sun.
Worth looking on facebook marketplace for solar and wind stuff. Sometimes bargains on there.
Been using Chinese wind turbines (Yangzhou Shenzhou 2KW) for the last12 years. They are good value for money when comparing their cost to other manufacturers, BUT, they tend to be thrown together and need a degree of remanufacturing and modification. As they are not approved by the moneymaking "Powers that be" they cannot be grid connected, and a "stand alone" setup requires understanding and a degree of "invention"
The subject is almost endless and one posting can't begin to cover it, so any questions, feel free to ask.
In my experience anything Chinese is not worth a toss!
I bought a 24v version of the one in the first pic last year but it was 12v
It was supposed to be 800W but it was much less, it worked OK through last winter on 12V but it was about 200W ish in a gale.
I bought another one this year exactly the same but this one is 24V (my houseboat is 24V) I am reasonably pleased with it I had about 250W out of it in just over 20mph wind speed and will see what happens in a gale when they come (soon)
The Chinese companies on eBay are stating 3000W, 2500W etc which is a gross over statement, I think the biggest alternators available for these is 400W...beware of the scam.
As I said I had about 250W out of mine in maybe 25 or maybe even a 30mph gust.
Mine is a 6 blade version and cost £149
PS the lantern type has the same alternator
There are 3 wires from the alternator all the same colour.
You can just get a (search words) " 3 phase bridge rectifier "the max voltage of the rectifier must be above about 200V coma 12V geni or 400V for a 24V etc because open circuit voltage output of the geni (voltage when battery is disconnected) is much higher, I slow plenty of margin for error those figures.
The rectifier must be able to cope with the current (Amps) so for a 12V geni about about 80A+ or for 24V 40A+ should be OK
The bridge rectifier has 3 input connections for the 3 wires from the geni which can be in any order. There are 2 output connections on the rectifier usually marked + and - for the battery.
Output from the rectifier can be attached straight to the battery or to a solar controller then to the battery.
Gel batts need the controller as do sealed lead acid batts but refillable lead acid batts do not need the controller however if they are small they will charge quickly and give off hydrogen and oxygen which can explode in the presence of a spark, you need a nuclear power station to cause one to explode in reality, its a small geni.
I had mine on a standard 50Ah car batt last year with no problems bigger batteries are even less problematic.
When they gas you can hear them bubble, the solution is to discharge them and keep them topped up with distilled water(not tap water)
Even if using a controller is is wise to use a bypass the controller to the rectifier (with solar replace the rectifier with a blocking diode.) when wind speed is low because controllers use power the rectifier uses less.
A 3 phase bridge rectifier will be about £3or4 on eBay
There is an eBay link on this site, use the link if you are going to buy anything especially if it is expensive like a wind geni.
That said Ibreeze, Rutland or Hornet(made in UK) are better.
