Finally, the tricky AGM starters and alternator charging issue has been backbenched with a 60A fuse/switch that can parallel them if ever needed.
Unfortunately the Victron alternator controller is 12v only, so no good for my setup, and a B2B is beyond my current means, so I’m going solar only and will see how if I need alternator charging in the end anyway.
Also of note, today at 2pm in full sunshine I saw (first time ever) a 0A input with a 35.6V solar reading, as my ‘boost’ setting took the lithium’s to 27.2, and the float was 26.7... and they were just floating... while the fridge was chugging away and the solar was on float BELOW the LifePo4 flat voltage at 100% (27.2v)
