I have two MPPT controllers, that I need to turn off during high voltage event, (HVD) using an external BMS. I have a BMS working that turns off charging to my multiplus 3000 using the 2-wire BMS assistant and the auxilary ports. Thinking I can use the HVD BMS shutoff wire which connects to the multiplus aux and splice them into my two MPPT controllers using two VE.direct non-inverting remote cables.
Is this possible? and if so, would anyone have a drawing the shows how i would make these wiring connections? The VE.direct cables use a sing yellow wire only, not a two wire pos and neg that the Multi aux ports use.
I have not consider using a BP100 due to the two way current limitation/fire potential.
Thanks in advance
