Yes, but he's not a real wind type.
Take the test like me.
Get off your machine.
Remove the hub.
Connect it to your GTI.
Take a drill and turn it gradually on the GTI's anchor file.
You will notice that as soon as your GTI hangs, the resisatnt torque increases suddenly.
For me this is not good because you suddenly slow down the wind turbine until it stops.

I can try this. Simply on the bench. Fast with my quick couplers. But I wouldn't know the speed of rotation.
Only production.
I noticed that when starting the injection it messes up. As if the grid hesitated
Red / green / re red, flashing green. Red hop ...
Style bon vent 17v hop green. And direct red for no reason. Always the same wind.
.But to say if the wind drops or if the propeller is retained is difficult based on the sound of the wind on the tiles.

How much did you pull out with the drill on the GTI. to get an idea.
I had +/- 100w maxi with the blades.

I had output about 100W too.

It's weird. Do you have the same voltage between the 3 phases before straightening?

Tomorrow after noon I violate the beast on the bench. We'll see. : Mrgreen:

For sure a Windyboy would be fine
I am waiting for my Amatek AirX hybrid regulator.
Which will independently connect my 2 GTI whatever the input source. With an extra battery, but I don't really see the point, except to act as a big smoothing capacitor. Or to supply on the dedicated 12V DC output

I would also test the 2 GTIs directly in parallel on the diode bridge, without exceeding the critical voltage of the solar GTI (14-28v) it is not protected by 2 fuses 30A like the other (10.8 - 27v).

Hello,
Normally your GTI are protected against overvoltage. It only engages me. Especially for mppt.
I had tested on a 10.5 - 28 V with more than 40 V at the input, they put themselves in safety. You must not exceed the voltage of the chemical condos at the entrance (when there is any !!)

To not mix everything up, we should continue on another post.

Obviously. It is scattered : Shock:
It would take a subject = go ahead, put your fingers in the socket !!! That tickles : Mrgreen:


Edit: surge protection. This is the DUMP LOADER. Not the condos. Nor the fuses: whatever ... For the fuses.

The Dump loader must be simple if not managed by an internal PIC, I think, a simple Op Amplifier type voltage comparator and hop off, if the threshold is exceeded, the arrival on the Dump Loader output.
Keep bypassing this output, it is possible that you stop the rotation and therefore protect it from storms. To be tested on a bench !! I don't think the fuses will blow anyway !!! they are on the entry line.
