Trying to understand the reason why battery current on my MPPT 100/15 is consistently showing as being higher than solar current. My understanding with the 100/15 is that a positive battery current number means current going into the battery and a negative means current leaving. But how can current going in to the battery exceed what is coming off the panels?
100Wx2 panels. In series. A/C charger off. BMV 712 monitor and Blue Sea charging relay.
