John just where are you measuring this voltage and current. If that is at the input of the Charge controller you have a big problem. The problem is your CC is called a MPPT, if those are the voltages and current you are reading at the input of the charge controller is a dead give-away you have a PWM controller.
The voltage on a MPPT controller should be spot on to the panel rated Vmp. Only thing that will vary is the current.
