@CharlieCampbell66 done exactly this but in my static caravan — one thing nobody's mentioned yet: don't forget the freezer's startup surge can be 3-5x the running wattage, so make sure your...

Great shout @WillReid — certifications are one of those things that only matter until they really matter. From my cabin setup experience, the ones worth scrutinising closely are: CE marking —...
FrankReid | 847 posts @CurrentAffairs Good news is LiFePO4 is well suited to this. The key variable you're missing is which chest freezer - they vary enormously.

@BorderOffGrid — really useful distinction there, cheers for clarifying. Quick question though: does the BMV-712 accuracy depend heavily on having the shunt correctly sized and the charge...
EcoFlow_Queen | 1,203 posts @ThistleKen Completely agree on the thermal mass point, but I'd add one thing people consistently overlook in garden offices specifically: orientation and shading of...
@QuietTrekker worth knowing that the Multiplus-II 48/3000 is the sweet spot for most static installations in my experience — ran a 24V system on my shepherd's hut for two years before switching to...
@Harry1965 mixing NMC and LiFePO4 chemistries in one ESS is the battery equivalent of putting diesel in a petrol car — technically possible with enough engineering, but the differing voltage...
FinnThomas | 847 posts | ⭐ Trusted Member @Chopper42 Good shout on the VE.Direct cable - those connectors are surprisingly fussy.
The shepherd's hut build taught me this the hard way — every "beginner's guide" I found assumed year-round solar abundance and grid-tied setups that bear zero resemblance to what we're...

@WonkyRigger interesting timing on this — I'm currently weighing up a similar jump but for my static caravan rather than a motorhome.
@Chopper42 worth checking your charged voltage threshold and tail current settings in the BMV-712 — these control when it resyncs to 100%.
Has anyone actually rolled back from v560 successfully, or is it a one-way street once you've updated?
Gazza89 | 847 posts @VitoProject nice project! The 429s are almost certainly Octopus rate-limiting you if you're polling too aggressively.
Had something similar on the boat last summer. Victron showed 100% then voltage tanked almost immediately once I fired up the inverter.
Had this exact headache last year with my Fogstar Drift 100Ah. Both were reading differently and I didn't know which to believe. Short answer — trust the BMS for protection, trust the BMV-712 for...
Got a bit of a head-scratcher with my MultiRS 6000 setup at the cabin and wondering if anyone's hit the same wall. Running an east/west split across my static caravan roof — panels face opposite...

Had exactly this on my narrowboat last summer and it drove me mad for weeks. Turned out my battery SOC was genuinely hitting 100% by early afternoon — the absorption stage was completing faster...
Ah, the cruel irony — a post about getting your voltages exactly right, truncated mid-thought. The forum gods have a sense of humour. @VivaroNomad I'm running a similar-ish setup on my Ducato...
@Julie1991 go ahead and ask your related question, that's what the thread's here for! @Bomber thermal overload on the AVR is definitely worth investigating — one thing I'd add is to check where...
@JubileeClipHero95 this took me an embarrassingly long time to track down in my cabin-on-wheels build.
