Another question: What are the big 150 ohm resistors for?

Have you calculated the break-even point?

I'm not a wind expert and if I'm not talking nonsense because with the little experience I currently have is limited to reading the net and a visit to a wind turbine owner. but it is the controller of the 3kw which puts the wind turbine at half mast in the event of too high a wind and at the same time it is he who turns it to follow the wind, the large resistance of 1000w is used in the event of boost, the time to put the wind turbine at half mast,,, until 1 minute after the guy I visited, if there would not be his resistance the device would burn. see his website www.castillon.be

by the way I went for a look at the joliet site,,, according to the photos and the technical data, if I'm not mistaken (to be checked with a person who would have bought one) it would be the same Chinese ones in 2kw, the difference comes mainly from the charger and the inverter (always according to the photos), the elements delivered are not the same either:

I did not receive the inverter, it is an option costing 250 euros, at joliet it comes with it.
the mast received is 9 meters, at joliet the mast is 6 meters (9 meters optional)
the batteries are optional for my case and for joliet
for those who are fan of the wallet:

at joliet: 2980 euros
in my case: 2492 euros (without inverter but the mast is higher which suits me given my location in the countryside)

delivery is included in the price, at the door of my home, at joliet ask them I did not see if understood or not?

I do not want to criticize or highlight one or the other, I apologize in advance to joliet and my supplier but I put this comparison which I hope is correct in all respects, for all those who would ask the question to compare my case and joliet.

be careful to also see the after-sales service which is perhaps better at joliet given the proximity, on my side the company is in italy and I contact them by email in English.

there are good and bad

Hello

I am familiar with Chinese wind turbines;
What can I say about it;
The base is of good design.
but the build quality is disgusting and some components are undersized.

The electronics are good to throw away (no reliability)
the mechanics and the generator are good with some modifications.

In battery version as they can be found everywhere on the net; I give max 3 years of battery life, the regulation is a battery burning machine

In the network version, I guarantee that you will burn the inverter at the first storm.

To sum up, I strongly advise you not to put these machines into service without making the necessary modifications.

As you will have guessed, I am part of it and invite you to visit www.wallonie-eolienne.be

We offer these wind turbines which after modifications by us offer the quality necessary for many years of use.

We have redeveloped a 100% secure regulation
On the mechanical side, we completely disassemble the generators for quality control and replacement of components.
All announced production values ​​are the subject of a measurement campaign

Hello,
can you expand the points please?

why is the reg zero? it is a shunt type regulator, ok for wind turbines (surplus > heating resistors) but why no one?

how long is it guaranteed for?

why would it burn the inverter? there are fuse protectors, no?

what are the changes to be made?

apparently the wind turbine has withstood the storms well:

the inverter is not connected I believe, just electric heaters.

Small precisions, above I spoke to you about the machines with servo-motor of gyration is the range from 3 to 20 kW

for the 2kW, I would like to point out to you that the power is 1.5kW at 9m / s and not 2 kW as announced by the manufacturer, in fact the machine is delivered with a wing of 3.2M while the specification is given for a propeller 3.6M
Concerning vibration problems, we have often noticed differences in weight, center of gravity and rigidity on the sets of blades delivered.
All our blades are assembled, pre-balanced and tested in our workshops
The hub also sometimes poses a problem (key groove depth, initiation of breaks due to poor machining, quality of the steel)
The ring collector on the 2kW also poses problems and must be checked

For the electronics, it snaps at you for no reason (poor quality components, telemechanical copy or other), the reliability is not there, being a critical point for machine safety, we systematically replace it with a industrial grade electronics

For servo-motor machines, the algorithms are incomplete (no cable trimming management, random reaction time, undersized or badly wired electrical load, etc.)

Basically in our experience there are defects on about 30% of the supplies.

tell me, it's not good to do what you do, like saying that your box buys very poor quality equipment in China, then supposedly gives them a beauty and then sells them twice as much on the pretext that since the passage between your hands are top material!

you just have to buy top-notch equipment right away rather than speak ill of the best-selling wind turbines in the world!

you have to explain it to us!

in our experience, you will quickly become disillusioned with your machine

what do you call quickly 1 years, 5 and, 15 years.

I have contacted people with this type of machine in France and NO issues with it, even one who has had one for 5 years!

I have contacted others who have bought supposedly top-of-the-range machines, from reputable brands and have only had problems with them, they are state-of-the-art machines.

It is like with the last generation cars, that worries and the fingers of not having bought a Chinese with simpler and more robust technology having 100 x less breakdowns.

you are at the top, you know all their faults, so tell me exactly all the worries that I am going to have with my FD8-10000, in how long, what should I do to anticipate, tell us everything?

AND THEN IF I UNDERSTAND CORRECTLY I NEED TO MAKE ADVERTISING SO THAT YOUR BOX DOES NOT SELL ANY MORE WIND TURBINES SINCE IT IS VERY VERY VERY VERY POOR QUALITY AND YOU ARE MASKING IT FOR MORE EXPENSIVE.

is that me and the members of the forum are wrong ?
