UPdate, problem resolved;
Turns out it was the control panel run button contact .
as a summary started out thinking the battery was being drained, then a weak ground, or alternator. all that ruled out and still it would not activate the panel when run was pushed so that it would start.
But, put a charger on it at 6 amps for 10 seconds and it would allow it to activate so the start button could be used.
I sent the panels to have checked and this was the issue, put it on and it has worked since.
dang little button contact cost me a lot of time and about $900 total with repair, and having a mobile come check other things.
education is priceless! but its better to learn from others.
hope this saves someone else some time down the road.
