Couple of other points having just read your latest post
1) According to the 2nd edition guide (3rd not yet ratified) there should be a second isolator lockable in the off position only by means of a padlock, near the aditional CU.
2) Have they earthed the array? - There should be an earth cable coimg from the rails to either an earth spike or the main earth depending upon your incoming supply type. (PME etc)
They are clearly incompetent and will just bodge the fixes to look right. - I know we're not perfect, your installation however would make a good case study for 'cowboy builders' or 'rogue traders'
