Little help with pre-installed wind generator

[antaris]

If the controller is just for 1 phase. (somewhat surprising) then it may be possible to modify if to 3 phase. Inside the box immediately after input wires should be a rectifier. Either 4 diodes or a bridge box with built in diodes. Find the output of these didoes which shouild be a DC point. You can make up a 3 phase rectifier that can take your 3 wires in from turbine to that 3 phase rectifier. essentially you need 6 diodes. Preferably schotky type. Take the anodes of 3 didoes to each of the 3 wires coming in. The cathodes (with a band or head of arrow) join together to give positive output. Take the cathodes of the remaining 3 diodes one to each input wire. (ie connected to the anodes of the first 3 didoes) The anodes of the last 3 diodes are joined together and make the negative output. The 2 outputs pos and neg couild feed in to the regulator if indeed it has one. Or sans regulator just feed to a battery.

re the output voltage yes 0 to 20 is probably right for 12v battery. The voltage will be pulled down by the current drain into the battery by internal resistance of the alternator and by the electrical load slowing the turbine. The big problem is that if the battery voltage is say 12.5 volts then nothing will go in to the battery until the alternator (generator) output voltage exceeds that voltage. then as the battery voltage rises with charge it will need more wind to get any charge in. A bit like solar panel but far greater problem than solar. Fit an amp meter just so you can see if it is doing any good. An MPPT regulator might be able to get more charge in at lower wind speeds.
However i think most people see solar as best and wind turbine just oo much trouble on a boat for the charge you get. ol'will

Indeed, the controller is an Ebay acquired single-phase. As I mentioned before, the ForgenNT outputs DC (as I found out later), so my purchase is on no use to me...

Interesting what you say about voltage being pulled down. I will connect to Amp meter and a spare battery and see what happens!

Thanks for the explanation on 1/3-phase controllers - I am sure it will help a kindred spirit trying to work out what's-what in the future! (these cheap controllers are all encapsulated in resin, so they cannot be opened... me thinks)

Don't expect much to happen unless it's blowing a gale ?
