Thanks, I think any of the above scenarios are possible or a weird combination of all of them.
One of the regular contributers will come and do a proper audit of the system and hopefully we can plot a way forward. 
It also seems that a decent and comprehensive monitoring system can go a long way in identifying the problem.
My gripe with the present situation- some installers seem to do a decent job of safely and correctly installing the hardware.
But they have no real understanding of the interaction between the different components, and how to troubleshoot issues like mentioned above.
Nor so they have the inclination to do so, when faced with a myriad of new installations every day that load shedding continues.
