Re-wiring the mess the builder left in my van. (Took the entire Victron system out and re-installed)
Everything works now, except for the current/watts polarity.
When the negative wires are in what I think is the proper shunt configuration I get 100% battery and inverted polarity on Watts, but when I reverse the negative wires I get 100% battery and zeros on everything below. From everything I have read reversing the wires should work.
Set-up
Bms-712
Multiplus 12v
Dc-dc 30
Mppt 100/50
4 100 Amph batteries
If not, provide a picture of how it's wired.
Fixed it, thank you. I ended up flipping the shunt resistor 180.
