I have just connected a MPPT 100/20 to two 12v LiFePO Batts (in parallel) and using Pure sine Nomad 2290W inverter as DC Load (https://waveinverter.co.nz/shop/power-inverter/pure-sine-wave-inverter/nomad-nps-2200w-pure-sine-wave-inverter/). Connection is fine, app reports batt volt good at 13.2, tracks reasonable pv voltages, removed jumper, set load settings to always on after default showed load state as off. Status doesn't change, no matter load setting (even waiting 2 min). I have no load on inverter, but mppt DC load relay should still be on right? I do have mmpt case ground to same ground as inverter, but no current/batts go to ground so I believe that is good. Help?
