most of that loss was in the inductor, as it was getting stinking hot, mosfets were cold. I've already wound a much better one with way less turns and much thicker wire ( my cheapy tester says 120uh)... will be able to test it better tomorrow if sun out( weather man says yes, but who can trust em).. but so far so good...
Re voltage, there is a significant distance to panels, and using 6mm cable I kept the voltage a little higher to keep the losses in it lower.. ( i can deal with heat where it is, easier)
If I can sort this properly( don't see why not but I never count my proverbial chickens) , I might be hitting you up for another couple of boards if you have any spare??
Thank you again for your help with this Pete ...
