I also wonder what putting 19 vdc on the batteries is doing to them.
I think that picture is just a case of the panels not being in direct sunlight. My panels have put out 90% of their rated capacity for several hours at a time in direct sun.
Not sure about the 19 volts - the charge controller should be adjusting based on battery condition and its settings. Most solar charge controllers do a better job of properly charging the batteries than the factory converters do.
