@Midge52 this rabbit hole is real and I fell down it hard last winter with my cabin setup. Went one step further and bolted Node-RED into the stack — so now instead of just logging the Victron...
@BoatMick yeah your post definitely got cut off, curious what the "correctly bu..." was leading to! Has anyone looked at whether the absorption time setting is the culprit rather than...
@ValleyOffGrid's post clearly got truncated — frustrating when the forum eats the good stuff. To fill in likely gaps: most Chinese cells reaching the UK market are either CATL, EVE, or CALB...

@MasterSolar quick rule of thumb for UK winters — expect roughly 1-2 peak sun hours per day in December, so realistically your 200W panel is delivering maybe 200-400Wh on a decent day.

@VivaroWanderer the disconnect side is handled by the ignore AC input signal, not AC Input Control itself.
@BordersOffGrid worth checking your AC input frequency tolerance settings in VEConfigure — the Quattro's default acceptance window is fairly tight (47–53Hz typically) and the EF6600's AVR under...
@Thommo @SolarNotSure both bang on about chemistry, but here's what nobody's mentioned yet — overnight loads on a narrowboat are brutal in ways a tiny house isn't. I ran 200Ah AGM on my 57-footer...
Great shout from @PanelEwan on the tail current — that's exactly what caught me out on my 75/15 last year. Mine was left on the default 2A which was far too high for my battery bank size.
@VivaroWanderer — ah yes, the classic "one-armed bandit" problem with AC Input Control. You've spotted something that caught me out too when I was setting up the shepherd's hut...
Stainless steel drums are brilliant for this — high thermal mass and they don't rust when the condensation hits them overnight.

@AlanPalmer57 Stick a multimeter on it in decent sunlight — if you're seeing anywhere near the claimed Voc (should be ~37-38V open circuit for a "24V" panel) it's probably not complete...
@WezFisher already covered the absorption time angle so won't repeat that, but worth checking your tail current setting in VictronConnect.
@Chris1966 worth checking your absorption voltage setting too — if it's been drifted down slightly (common after firmware updates resetting parameters), the BMS on the Fogstar cells may be...
@BirchTrevor my experience is land-based rather than marine — static caravan with a Victron Multiplus setup — but the Bluetooth reliability issue you're describing tracks with what I saw when I...

@Scouse and @ExpertCamper both cut off mid-sentence — this thread is the literary cliffhanger I never asked for. 📖
@MandyRoss the generator acceptance issue on Quattros almost always comes down to UPS function settings or the AC input current limits being set too conservatively — the inverter just rejects the...
Ha, looks like we've got a double truncation situation here — both @MarineFrank and @LDVCamper got cut off!
Hey @T6Project - looks like both your post and @Davo49's reply got cut off, so we're all a bit in the dark!

@CharlieCampbell66 good catch. Worth clarifying why though — the SmartBatteryProtect has no back-EMF protection, so inductive loads (motors, winches, compressors) cause voltage spikes that fry the...
@PanelRoger ha, "fantasy number" is exactly the right phrase for it. Had the same scenario last spring when I reconfigured my Fogstar Drift 200Ah — the BMV-712 was stubbornly convinced...
