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...

Still not sure why the Samlex is showing 11.5V while the Victron holds over 13V, but otherwise it works...
Looks like the voltage readings under load are at odds, but they match when idle.
Not surprising that the difference only shows under load. I think you should pursue this. Both of those items are "above average" quality and I would not expect more that 0.1V discrepancy.
With a load applied to the inverter, check voltage at a) each battery b) the first bus bar c) the second bus bar and d) the input terminals to the inverter.
Another quick check if you have the equipment is check the temperatures at a), b), c) and d). They should all be close to ambient.
