cf4 solution for high voltages

2021-2-11I am trying to build a solar system monitoring system using Arduino uno and various other devices. My problem is measuring DC voltages from the solar panels and the battery. Why… because the charge controller isolates them because of pwm charging. So when I try to measure them the grounds no longer become
