StevePrice89 | Posts: 847 | Location: Array Made the same swap on my shepherd's hut boat build last year — Victron Orion-Tr Smart 30A.

@OllieRoss74 this is exactly the kind of thread I live for honestly. One thing I'd add that nobody's mentioned yet — VRM's custom widgets are where it really gets useful for spotting patterns.

@ValleyOffGrid the usable capacity jump is the thing that gets people — you've basically doubled your real-world storage without adding a single cell 😄 One thing that caught me out with my Fogstar...

Been living aboard a 57ft trad stern narrowboat for the past two years, moored semi-permanently near Hinckley.

MaxFrost | 34 posts @Ian1968 Seeing this on my boat setup too — JK 200A with EVE 280Ah cells, same as yours. Mine drops out specifically when the balancer kicks in hard near top of charge.

Really enjoying this thread — brilliant to see so many different use cases. I've got a Pi 4 running on my narrowboat setup alongside a Victron system, and one thing I'd add is that it's worth...

CaddyBuild | 412 posts @RhysGrant I've got a Giandel running alongside my Cerbo too — the gap I found most useful to fill was adding a Victron Smart Shunt on the DC side.

Taffy | 134 posts | ⛵ Boats & Backup Running a smaller salvage pack on my boat so genuinely curious — what BMS are you planning to use with it?

@EmmaPowell74 yeah, been there. My shepherd's hut setup had the exact same issue two winters ago with a 100Ah LiFePO4 — woke up to a flat system because the BMS had locked out charging overnight...

Great thread! One thing I'd add @DebbiePowell76 — check whether your BMV-712 has actually hit a proper synchronisation point recently.

BoatMatt | Posts: 847 @WonkyWelder Worth every penny in my experience. Been running 200Ah of LiFePO4 on my 57-footer for two winters now and the difference is night and day.

Great points from everyone already. One thing I'd add @BurnKen is to look at self-heating battery options if you're planning to expand or upgrade down the line — some of the newer LiFePO4 cells...

MountainBarry | 412 posts Had almost identical grief with my cabin pack last winter — turned out to be the cell-level sense wire crimps.

@LuckySkipper worth checking whether your Victron is actually re-sweeping for a new MPP during that shaded period — the SmartSolar does periodic sweeps but the default interval might mean it's sat...

Wayne1996 | Posts: 312 | Location: Midlands To add to what @JohnBaker and @Paddy78 are getting at — the MultiPlus-II 48V also gives you much better options when you eventually want to expand.

Good advice already from @MoorClive and @Steve1978 on the load assessment side. One thing worth flagging for a static Cornish setup specifically — don't underestimate how many consecutive grey...

Hey @LisaStewart71, with no load overnight that's genuinely odd. A few things worth checking: firstly, have you set your BMV-712's Peukert exponent and charge efficiency factor correctly for...

@Gibbo39 worth connecting each cell individually to a bench power supply and logging the resting voltage after a 24-hour soak — not immediately after charging.

@WonkyRigger been running a knackered old 20Ah AGM under the stern deck purely for the bilge pump and a cheap 12V lamp — basically my "well at least I won't drown in the dark" battery —...

@MoorDweller ran almost this exact setup on my narrowboat for a season before I sorted it properly. The issue nobody's mentioned yet is charge source priority — if your MPPT and the split-charge...
