Using 6 12v bat with magna2000 inverter/charger and mppt100/50 solar charge controller. The bm700 will show the ah increasing when sing the onan generator. However, when using the solar system the ah don’t show increasing. I have the shunt connected to the (-) post on batteries and the load/charger side of shunt connected to the magna2000 (-). Why does it display correctly when using gen but not when using solar only? Do I have something wired incorrectly?
