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.

Went upto Rogers after work today and what a learning experience it was helping solder on the wire to the board
So VS1 & VS2 now have 50sqmm wire on each pad and had enough length off the toroid wire for the battery connect so 65sqmm
So the 50sqmm wire for VS1 & Vs2 will be bent down to attach to each choke, now we did measure the inductance using Rogers meter and both chokes came in a 24uH within a point of each other so good to see they are matched.
Now I did mention about charging the caps before turn on and suggested the battery connect would do it and got told well the inrush of current to charge the caps will show the fireworks and a bleed resistor is required to limit the current on the positive rail to charge the caps. So lesson learned and that is one thing I never read in all the reading on this inverter.
