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.

Cheers Tinker, I appreciate you input

As I see it
Cutin v=charge v required by the battery

"So your last paragraph makes no sense"
Wouldn't this depend on the batteries state of charge?

"Do read up on the part where it says that wind generators should always have a load connected to avoid runaway in high winds."
I also understand this, a switching device will still brake the mill as the 'on' time verses the 'off' time would depend on rpm.More 'on' means more brake

"That is not a good idea IMO, I think you completely misunderstood the function of the capacitors Gordon mentioned in his post above."

I would imagine that voltage doublers, triplers etc, are designed for increasing the dc volts from a ac source, I believe they work by stacking the capacitor charge voltage onto the one side of ac swing voltage

Source to load impedance will also change

I will get a battery on today

I guess I just can't get pulsing to the load in low wind conditions out of my head
I would have thought that charging a cap would be easier current wise than a battery as the cap doesn't really care what voltage it is charged to
I keep thinking about those cheap car battery charging solar panels that you poke into the cig lighter socket
Blinking led, more sun, more blink

What are the henrys on a fp single coil? 100 80 60 etc

Thanks again
