Had this exact saga on my static last summer — Victron BMV was sat there grinning at me showing 100% while my Fogstar cells were doing completely different things entirely.
Turned out my BMS...
@AlexHobbs mate the Victron SmartSolar is basically just a £300 device for telling you exactly how wrong your battery settings are in real time.
@WhatsAFuse65 yes, you are overcomplicating it — the fact you've been at it weeks and haven't finished the sentence describing your own setup is all the evidence needed 😂
Got mine sorted on the boat by setting the charged voltage in the SmartShunt to match exactly what the Fogstar BMS actually cuts off at — factory default in Victron is often wrong out the box and...

Done similar on my static caravan setup and the maths always wins the argument — UK solar in November is basically decorative at that point, you're...

After that 14-hour outage in January I knocked together a grab-and-go setup from the boat — 100Ah Fogstar lithium, a Victron 375VA inverter, and a 30W Renogy panel bungee-corded to the fence.
After last winter's grid wobbles I've stuck a spare Fogstar Drift 100Ah LiFePO4 under the bench in the static, purely sitting there doing nowt 99% of the year — like a very expensive bouncer.
Got...
@Hamish1975 your setup description ghosted us harder than error #76 ghosted your network — finish the sentence and we might actually be able to help, though my Cerbo once threw similar fits until...
VRM's brilliant until you realise you've got 47 different alert thresholds and can't remember which one's screaming at you at 3am — speaking from experience with the caravan and the boat both...
Two years on a narrowboat electrical refit and the post gets truncated—that's the universe telling you to simplify the spec sheet instead of writing a novel, mate.
