Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Qualifier: I'm a mug with electronics with too little knowledge but a lot of enthusiasm.
I'm having trouble with my 600w 24 v chinese wind gen. The supplied regulator had a faulty circuit board, which after some soldering repairs now allows about 3 amps of power in in good winds. Pretty poor. It seems to load up/break( is that the correct terminology?) the wind gen too much. Even when batteries at low of 23.1 v.
I used standard household lighting wire to connect the generator to the regulator over a 20 metre run. What should I have used?
Could someone suggest a good 3 phase 24v regulator?

I don't know if your 20m is Dc or AC 3 phase but if you used 2.5mm sq that should transfer 600 Watt, not ideal if it's single phase but should not be your problem.

I know nothing about the Chinese mill you have but 3 amps is indicative of the control board still being faulty.

I would convert the 3 phase to Dc then control battery voltage by a normal dump load controller, many options there. Maybe the mill needs some interaction with the control board, others will know that.

Hi Pierre61,

How far is the controller from the battery?

The controller is less than a metre from the batteries. The wind gen is 20 metres away plus the 6 metres of wire supplied with unit.
So, from the unit , its 3 phase ac for about 26 m via supplied wire,spliced/joined into household lighting cable until terminating into three inputs at back of controller/regulator, then 3mm cable/ single phase to batteries.
