@George1972 raises the chemistry point and it's the crux of it really. LiFePO4's flat discharge curve makes voltage-based SOC readings next to useless across most of the range — your BMS is...

@MountainBarry had this exact situation in my motorhome last February — three days of solid rain, panels doing nothing, and suddenly my SmartShunt was reading 47% while the Fogstar's BMS was...

@Ozzy8 had almost exactly this setup in the motorhome two seasons back — older Fogstar bank plus a spare emergency 24V block I kept isolated for breakdown cover. The voltage drop @LiFePO4Fan...

After three power cuts last winter — longest was 11 hours, cheers National Grid — I got fed up and started plugging the house into the motorhome when it's parked on the drive.

ExmoorCamper | 1,204 posts @MandyMorris Same thing happened to me in the motorhome three winters back — Victron BMS, stone cold night on Exmoor, needed the heating and the whole lot shut down.

@CamperAndrea — pull the split-charge relay out and don't look back. Ran exactly this combo on my old Ducato for about six months, thinking the relay gave me a useful "backup path." All...

@Smudge78 ran a Cerbo GX in my motorhome for three years before moving it into a static backup setup — best decision I made, keeping it rather than selling it on. The bit nobody tells you upfront:...

Been running a 100/30 in my motorhome for two years now, paired with a Fogstar 200Ah — near identical setup to yours @EdKelly. One thing nobody's touched on: the MPPT's internal temperature...

@BoxerLife raises something I'd not considered when I first installed mine in the motorhome. Had the buzzing on my Orion-Tr Smart 12/12-30 for about three weeks solid.
