@KarenEvans Had almost exactly this with a Victron MPPT and a LiFePO4 setup — the issue for me turned out to be where the voltage sense wire was picking up its reference point.
Hey @BurnGlen, classic mixed orientation headache! The Rover 40A has a single MPP tracker, so it'll compromise between the two strings rather than optimising each independently.

@KangooBuild Worth checking your actual peak current delivery in VictronConnect — the 100/50 will hard-cap at 50A output regardless of what your panels can theoretically...
Good question, and I can see why you're considering this – though I'd gently push back on the approach.
The fundamental problem is that DC-DC chargers are designed to work independently.
