I’m about to swap out my CTEK DS250SE as I have upgraded to LiFePo4 and I don’t like the charging profile for Lithium. On this setup the PV -ve and battery -ve go to chassis ground so are common
So I’m going for Orion TR DC-DC and Smart Solar MPPT. My question is - it looks like the PV -ve and output -ve are common despite having 2 connections - so am I able to still have common pv-ve and common output/battery -ve wire - it will save me a hell of a lot of stripping out wiring!
