Which regulator for a "Piggott" type wind turbine?




by titiyador » 15/11/14, 07:42

Hello everybody

I self built a small Piggott wind turbine of 200w max a few years ago, but unfortunately, having not found an affordable solution for a charge controller, I had gradually abandoned the project ... Good today I would like to finish it once and for all and see it finally produce power!

The problem is that I have never found an affordable regulator. So I found several regulators (see links below) but I don't know if they would go. The wind turbine is in three-phase 12v, that would have to go out in single-phase output of the regulator. Many had spoken to me about a regulator with dissipator of energy when the batteries are full to avoid a runaway of the wind turbine. In addition, it's good, the heat produced in this case will serve me!

Here are the links, if you can give me a feedback on the type of regulator that could go:

The last link seems to meet your needs and in this case, the diode bridge of the other request is not necessary.

The output wires, red and black are to be connected to the battery and it is not single-phase but direct current.

The one at 87 € is valid. Works 12/24 automatically. Braking is also planned. It can be mounted on the machine and descend only a 2-wire cable since it is waterproof. I would rather vote for that one.

In fact the first link must also be valid but it is not specified if there is braking beyond 15 v.

Hi Izentrop, thank you for your response.

Regarding the regulator at 87 €, I like it too. By cons I do not have to buy a diode bridge for this one either, right? I see that the inputs are three-phase in the housing ...

There is a battery output (direct current, red and black wires in the middle on the image), but what are the two red and black wires on the right for?

I had read several times that for a wind turbine it is advisable to place a resistor, which "starts up" (ie the current is dissipated there) once the batteries are full to avoid runaway of the wind turbine. What do you think? Are the red and black wires on the right made for this?

The thank you box

Hi,
This is important for load resistance. Here they are integrated.
For batteries, it is also necessary to know if the regulator protects from overcharges and deep discharges.
For more information, contact the seller.
Another better informed link. Will have to ask them what an electronic brake is;)

If your Piggott wind turbine has an automatic tilting system that prevents it from turning too fast in strong winds, it does not require load resistance. Image AMHA.
Regulation should be as simple as possible then;)

Hello,

yes the wind turbine has a feathering in case of strong wind, but good considering that I begin in the matter, when I hear a lot of people tell me that it needs a shunt regulator, (ie with overflow resistance apparently) I prefer to listen to them. Finally after the batteries will almost never be full, there will always be a load (pump from 14 to 20w) rotating continuously for a hydroponic irrigation system. So good ... In any case I will try with the regulator at 87 € and we will see!

Thanks again, Tim.
