Voltage drop on inverter
I have a Samlex 3012 inverter charger that is powered by 4 x 100 ah LIFEPo4 batteries. Each of the batteries is wired separately to a bus bar using 00 welding cable, this bus bar feeds another one tha...

What are the amps showing on the monitor while it runs the MW and shows 13v ???? You never said.
I suspect the inverter's neg input is from the wrong end of the monitor's shunt, so the inverter is "seeing" the lower voltage and the monitor is not.
Why that much of a drop, don't know. With my zoo of wiring, I get about a 0.7 drop running the MW. If the batts are 12.7v to start with, I see 12.0 while the MW is on. (I could do better than my zoo does, but don't need to, so it is what it is.)
Under load the Victron is showing about 128 amps of draw, the Samlex is showing 124, that seems pretty close. The Samlex is showing the 11.5 v under draw but isn’t throwing any low voltage warnings. First thing I will do is connect the inverter directly to the battery buses and see what I get.
