I have a Victron-702 used in a solar system, 640W solar panels, 60A MPPT controller, 2 x 200AH batteries, wired for 200AH @ 24v. My problem is that the Victron consistently under reads voltage cf controller. eg controller 28.4v cf Victron 27.6v, this creates the problem that the batteries never reach 100% capacity according to Victron. I have checked the true voltage with a multimeter and controller always shows correct voltage. Does this indicate that the Victron has a fault?
