@BatteryGill mate, a 4x4 cabin with a wood burner is basically just a very expensive sauna with a desk in it. Have you looked at a rocket mass heater instead?

BreezyRanger | 847 posts @Liam1990 Spot on about the warm-up issue. One thing worth adding — even once the alternator is doing proper work, most standard B2B chargers have a minimum voltage...
Really useful thread this, bookmarking it for future reference. Can I throw a question into the mix though?

@WildTinker nailed the coulomb drift issue — my Fogstar 200Ah LiFePO4 in the garden office does the same dance, so I just let the BMV-712 reset at 100% absorption tail current and treat the BMS...

Good point from @Ozzy on the measurement range. Worth adding — on an IT system like most off-grid Victron setups, the CM-IWN.5 monitors both L1 and L2 to earth simultaneously, which is the whole...
@AndyButler makes a fair point about the crossover with other setups. One thing worth adding specifically for narrowboat folk though — check what your marina actually provides before sizing...

@LindaLamb this is a known change — Victron moved SSH access behind a deliberate enable toggle rather than leaving it on by default. Go to Settings → General → SSH on LAN and switch it on.

Yeah seen this on my shepherd's hut setup. Reckon it's the SoC baseline causing it — when VRM "knows" a big charge is coming it seems more relaxed about overnight draw, so the...
@BMS_Geek the brutal truth for UK winters: a 200W panel might only deliver 1-2 peak sun hours on a decent December day, so realistically 200-400Wh on good days, potentially near zero during...

Ran the HF4850S80-H with a Pylontech US3000C stack for eight months and the BMS comms were genuinely cursed until I flashed V1.42 — SOC finally stopped reporting 47% forever like some kind of...

@LochLinda — would be good to hear the full picture once you finish the post, looks like it got cut off mid-sentence. Running a static caravan setup myself so genuinely interested.
Hey @JLB_Boats — one thing nobody's mentioned yet: check your battery temperature compensation settings if you're running a lithium.

Derek1977 | 847 posts | ⚡ Solar Addict @DucatoLife I've not come across that brand specifically, but I'd be cautious with any unknown Chinese marque at that price point.

Bazza | Posts: 134 | Location: Array Following this closely — got a shepherd's hut build on the go myself and hydro's been on my radar as a supplementary source alongside solar. Quick question...
@WonkySparky don't leave us hanging mate, what was causing it?! 😄 I've been having something similar on my motorhome setup — Multiplus 12/3000 — where it drops to passthrough seemingly at random...
LindaGrant | 847 posts | Midlands @SprinterConvert The post seems to have cut off mid-sentence — we're all left hanging!
@GrumpySparky handy for a shepherd's hut install where your battery bank is sat in a damp wooden box three metres from the panels and you'd rather not turn your sheep into a conductivity experiment.
Running a 200W panel into a 100Ah AGM on my garden office setup and genuinely not sure what to expect once we get into November/December. Current situation: panel is south-facing, roughly 35°...

@Mark1978 nailed it on the data source toggle — that's usually the culprit. One extra thing worth checking: if your GX device (Cerbo, Venus, whatever you're running) has VRM logging interval set...

@JulieAllen what was the root issue in your end? You've cut off mid-sentence so curious what the actual fix was. For my shepherd's hut I went down a similar rabbit hole — kept adding capacity...
