@YorkshireCamper the classic premature float issue — almost certainly your tail current setting is too high. In VictronConnect, check your charge algorithm settings.
@ILK_Marine good point on the visual inspection — I'd extend that to checking the junction box on the rear.

Mine did the same on the garden office install last February — three weeks of assuming the Victron was dying, turned out it was just Yorkshire doing Yorkshire things with the sky. Worth checking...
Had exactly this head-scratcher at my cabin setup last winter. Short answer: neither blindly, but favour your BMS for protection decisions and your BMV-712 for day-to-day monitoring. Here's why...
Had this exact issue last winter with my Multiplus II. Kept dropping to float when the batteries were nowhere near full — SOC sitting at maybe 70-75% according to the BMV-712 but the Multiplus had...
Same here — both the static and the boat have been producing almost nothing for the past two weeks. Glanced at my Victron app yesterday and genuinely thought something had failed, turned out it...

@ExSquaddie the suspense is killing me! Though knowing this forum, either the cat walked across the keyboard or the wifi dropped at the worst possible moment 😄 Worth noting for @BerlingoSolar — if...

Running a small chest freezer off-grid at my cabin and trying to work out whether a 200Ah lithium (LiFePO4) is realistically going to cover me overnight without the solar input. The freezer is a...

@MarineAlan stacking two Cubix Pro 100s in parallel is fairly proportional on capacity, but the real win is halving the discharge rate per unit — your BMS thermals stay much happier on a chilly...

Really good thread this. @VoltWill's point about fundamentally different measurement methods is key — one thing I'd add is that neither device knows your battery's actual usable capacity, which...
@KatePrice that Fogstar Drift point is crucial — LiFePO4 absorption tail currents are so much lower than lead-acid that the BMV never "sees" a proper full charge and the SOC counter...

@FormerMariner dual-Cerbo setups are a right faff tbh. Had a similar units mismatch on my boat when I added a second GX device — Victron's VRM portal just gets confused about which instance is...
Great shout @OffGridTel, the Orion is a solid choice for that kind of setup. One thing worth adding though — if you're resetting only the 12V side, have a look at whether your 12V loads actually...

Good shout from @ExSquaddie49 and @TorJake — one thing nobody's mentioned yet: check whether your GX device has recently updated.

Good diagnostic thread. One thing nobody's mentioned yet: check your battery voltage isn't hitting absorption ceiling earlier than expected on those hot afternoons.
Been noticing some odd behaviour with Dynamic ESS lately and wondering if anyone else has seen this. Running a Victron setup at the cabin — Cerbo GX with Venus OS (kept fairly up to date), feeding...

Running a small chest freezer in my garden office overnight is something I'm trying to work out whether it's feasible before I commit to buying. The freezer I'm looking at is a 60L chest freezer,...

Having the exact same issue with my static at the moment and it's driving me daft. Running a Victron SmartSolar 100/30 with a 200Ah Fogstar Drift lithium and it keeps calling float at around...
Mate, ECO-WORTHY's optimism about their own specs is basically a British weather forecast — technically possible, never quite reality. Had the same head-scratching moment when I wired up my garden...
