Help please, our proven 6kw is misbehaving, we have wind but turbine is only just about moving, we lowered it last week and found brake was slightly binding so adjusted, greased everything and it seemed to turn ok, hauled it back up then no wind for 5 days, it has now got windy and turbine trying to turn but not getting there, ideas please before we lower it again.
Thanks

Hi,

There are more learned types on the forum who I am sure will be along shortly to assist you but in the mean time if you had everything free running after adjusting the brake is it possible that you have a short somewhere which is effectively electro braking the turbine?

Almost certainly a short somewhere. Not familiar with the Proven but is there a rectifier box between the turbine and inverter?  It is possible that one or more of the rectifiers has failed short circuit. This will also have the effect of "braking" the turbine. I had exactly this failure on my Futurenergy turbine, even in a strong wind it was barely turning.

I am sure a Proven expert will be along to give you more pointers.

Thank you, it is certainly looking like a short circuit, will bypass the possible problem and see if that cures it.

Can the cable be jointed with a torpedo joint/underground sea joint?
May save replacing the cable?

2 torpedo joiners and a couple of meters of cable have sorted it.

I used one about 40 years ago.  A single Tee version actually.  Admittedly only mains voltage.  It was difficult at the time - never used one previously and not an electrician, plus it was a wire armoured cable - and still going (fingers crossed now Wink).  It even needed a heater to help with curing, as I recall.
