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.

The number of turns is the number through the hole. Looks like 4 to me.

As phil99 said, 4 turns, and with those cores, I think the inductance meter is wrong.

So Keepis I will do the other one and see if they do read the same with my meter and on talking with Roger he did say he had the crimping tool so one has to wonder if he also has an inductance meter too   I did get the 4 8mm lugs today too and still have one lug to put on the primary which I have.

So just got the connections on the main board to do and make up the LCD where I will pinch one from Mike's collection of boards then this inverter can start to take shape  

Got next Tuesday off work as I am getting my car serviced so will have a few hours to get more done and hopefully it won't be too long before testing can start.

Regards Bryan

Is 35mm2 too thin of a gauge for a 6k inverter. I would say 50 to 70 mm2 would be better.

Again I am no expert on this subject.

Me thinks if using 65sqmm in these toroids may be lucky to get 2 turns

Those chocks do not have much space in them. The chocks recommended by Dex are perfect but very expensive at about 100 Euros each. Perhaps we can find a better solution.

I am glad I took my inductance meter to work and several goes did say the same result 9 UH So a question for the brains trust is 9uH too low for a choke.


9uH seems low.  I guess the cores you got only have 60u so that could explain the low inductance you are getting.
