How much current?

This weekend I happened to be on the dock around the time that the sun was most on axis. I took a look at the charge controller and saw this...

I have also been running the lights until 0100 each night which is around 5 hours at this time of year. The battery voltage has been over 12.5v for the entire week, including the night after a poor charging (cloudy) day on two separate occasions. I have yet to see how it behaves with several consecutive days of poor charging, but I am confident it'll be OK
