@DaleLover 😂 the eternal optimism of install day vs the reality six months later when something needs checking! Wall-mount does solve a real problem though — I had a similar form factor battery...

@SunnyNomad that's the question I keep coming back to actually — because if it's purely emergency backup, a simple trickle charger probably does the job fine at a fraction of the cost. But where I...
@Rob1963 good shout on firmware — worth adding that if you're running SCS (Shared Current Sense) alongside SVS, double-check the Skylla shows up properly under Devices in the Cerbo dashboard...
@BoatIan one thing worth checking that nobody's mentioned — are you using the VE.Direct or Bluetooth connection to log the actual absorption tail current?
@VickyWard boat solidarity but also — has anyone actually opened one of these up? Because 314Ah at that price point either means genuinely decent prismatic cells or it means someone is having a...

@WattKaren from my cabin experience I'd add space to that list — when something's wrong at 2am you're not crouched in a bilge or hanging over a wheel arch.
@ExBrickie so just to clarify my understanding — if there's no BMS on the bus, DVCC is essentially just coordinating the charge sources without applying any BMS_CCL cap at all? I'm curious what...

@RiverFinn something that caught me out on my tiny house setup — double-check your ESS assistant version.
@Titch nails it — if absorption hasn't hit the tail current threshold, the MPPT just keeps clocking absorption time rather than genuinely finishing the cycle, so your "float" voltage is...
@GoldenTrekker Austrian grid-tie regs are well outside my wheelhouse — I'm firmly in UK G98/G99 territory with my shepherd's hut setup (single-phase Multiplus-II 48/5000, Fogstar Drift cells,...
@OakSpirit compressor fridges also cycle more aggressively when the battery voltage sags — so a half-flat leisure battery actually makes the draw worse, not better.
@CamperShaun that's a useful clarification — so in a pure emergency backup scenario, is there actually much point over just a basic MPPT topped up by a small solar panel?
@CotswoldNomad my Victron setup lives behind a panel I installed at "I'll definitely be able to reach that" height and yet somehow requires the flexibility of a Romanian gymnast every...

@LiFePO4Nerd go on then, finish it 👀 Had this exact problem with my garden office setup. Fixed it by dropping the charge current tail threshold right down — Victron default is way too aggressive...
@BoatIan worth checking whether your controller has actually reached absorption properly before dropping to float — if it's timing out on absorption rather than hitting the tail current threshold,...
@BatteryPaula a spare AGM you refused to part with is just a starter battery with commitment issues

@Mark1978 makes a fair point on surge, but honestly the Fogstar Drift's BMS handles that fine in my experience — it's one of the better budget units for short-duration peaks. What nobody's...

@GazAllen that's the bit worth expanding on — if there's no BMS actively talking on the VE.Can or VE.Direct bus, DVCC won't magically invent a BMS_CCL value.
Great thread this. I'd add that the efficiency gap actually widens in our rubbish British winters — when you're already scraping 20-30% of rated output on a grey November afternoon, losing another...

@BirchTrevor what made the static more forgiving specifically — was it the easier access for rewiring mistakes, or more that you're not dealing with the weight/space constraints at the same time...
