Some issues that I need to have checked out: Power panel has been rearranged by the Solar installers and their breakers repositioned - issue?
It's possible this is the source of your problem. It's pretty easy to forget to tighten a wire back down while moving things around. If they didn't tighten down one of the hot wires to your EVSE properly, that would possibly cause an intermittent problem. I would ask them to check all the connections next time they are in there to make sure they are tight.

( Solar system itself is still waiting to be commissoned by power company - so it is not producing and not actually connected at this point)
It may not be producing now, but I'm willing to bet that they tested the system after they rewired your panel. It's possible they made a mistake and damaged something, but I doubt it. One other possibility is that the solar system created an over voltage condition in your house. My system occasionally creates a slight overvoltage condition in my main breaker panel, as discussed in the following thread (we went a little bit off-topic):
Our LEAF disrupts our PV System while charging

During both times the car went belly up, it was charging while my wife was running the washer/dryer - issue?
Possibly you could get an undervoltage condition with your car drawing 3800W and your dryer drawing 4800W and perhaps your air-conditioner running, etc.
If you have a voltmeter, you might want measure the voltage at an unloaded circuit near your breaker panel under different conditions to see if undervoltage or overvoltage conditions might sometimes occur. (For reference, in North America, the proper voltage range is 115V to 125V for a "120V" outlet and 230V to 250V for a "240V" outlet.)
I don't know how the AV EVSE or the charger in the LEAF respond to over- or undervoltage conditions. It is possible that the LEAF will throw a fault code and shut down in these cases. I have never seen that happen with my LEAF, but perhaps in your case it detects an undervoltage and gives up. It might be worth investigating for the sake of science!
