Measuring Voltage and current of solar panel

Good day, guys! I am currently doing a project on the solar panel, and I am at the last step, which is to measure the voltage and current of the solar panel so as to know the power to display it on my dashboard. However, I am with a problem. So my voltage value was correct when I haven't connected it to the charge controller but however, when I connect it to the charge controller, it is measuring the wrong voltage value (which I suspect is from the 12V battery) The solar charge controller has…

I was referring to this one sir.
