Call me a Idiot and I would agree. Found the problem, I was connecting the PV reverse polarity. I will not go into details how this happen, but it happened and I am totally embarrassed. Every thing calmed down after I connected it the right way round. @BritishRacingGreen yes nothing happen regarding solar charging when the battery was 52V and the PV at 53V. I didn't even get a PV voltage registering on the display. I then increased the PV voltage to 65V and SCC came alive and after a few seconds started to charge the battery.
I am just totally amazed at how hardy the SCC is and that it took my abuse with a smile and protected itself!
Thanks guys for all you help.

Hi I replaced all the Capacitors with Hitano Low ESR capacitors and that solved the problem. I must still just test all the functions but all looks good so far.
Thanks for your help.
