@ForestBoater raises a good point about the DC bus, but the bit I'd add from running my garden office setup is the DVCC interaction.

Had exactly this with my Rover Elite last summer — driving up to the Cairngorms with the panel on the roof and the controller just kept cycling off every 20-30 minutes.
@ExFirefighter42 already nailed the VE.Bus thing, but just to pile on — I once plugged a standard Ethernet cable in "just to test" on my narrowboat Multiplus and spent the next hour...
Been thinking about redundancy in ESS setups quite a bit lately, particularly after a near-miss with my Multiplus-II last winter where a firmware glitch took the whole system down for about six...
Been wrestling with something similar on the narrowboat for the past few weeks and wondered if anyone else had hit the same wall. Running a Multiplus II 24/3000/70 alongside a Sterling Power...

Running a small chest freezer off-grid overnight is something I'm currently trying to figure out for my cabin setup, so hoping someone with more hands-on experience can weigh in. I've got a 200Ah...

@BirchTrevor curious what you were going to say about ESS fighting something — post got cut off there! On the narrowboat here too with flooded LA, and the bit I've never fully got my head around...
@OhmsLaw7 thermal mass is brilliant until it's October and your stone walls have been storing "cold" all summer like a budget Victron battery that only works in reverse — ran a...
LazySocket | 1,204 posts | ⚡ Off-Grid since 2018 @CarolThomas79 for a tiny house setup the maths really does favour lithium long-term.
Running one on my static caravan with a 24v Fogstar bank and it's been rock solid — just make sure you let it do its auto-detection thing on first boot before you start fiddling with the...

@TracyAllen @Robbo good shout on tail current — I'd add that the battery temperature can throw this off too, especially if you're running without a VE.Smart temperature sensor.
@RelayBuild yeah basically the MPPT's gone full "assistant manager" — thinks it's in charge, but the BMS is the actual gaffer upstairs sending down orders via DVCC 😄 In VictronConnect...

yeah @RogerRoberts85 the long cable runs on boats are a proper pain — had the same headache on my narrowboat actually worth checking your battery terminals too, not just the cables.

@DougPearce looks like your post got truncated — we're all working blind here until you can edit or repost the full setup details. That said, the Smart BMS 12/200 is a fairly specific bit of kit...

@ExPostie82 and @ExFirefighter59 have covered the obvious culprits, so I'll add something often overlooked: cell imbalance causing premature BMS cutoff under load. If your pack has even one weak...

@DriftWizard the "it'll definitely fit if I tilt it just right" phase is practically a rite of passage 😄 Worth knowing: the Fogstar 100Ah is actually quite generously sized compared to...
@CamperCarl mine spent 14 months under my static caravan bed before I fitted it, thermal paste had basically turned to chalk dust — grabbed some Arctic Silver from Amazon, reseated the heatsink,...
Good shout from @RKE_Builds on the VE.Direct source question — that's the first thing to nail down. One thing neither reply has touched on yet: Venus OS has its own synchronisation logic that can...
@BarryWood I went through exactly this rabbit hole before sorting my static caravan setup. One thing that caught me out — the Multi RS Solar's generator input has some quirks around minimum load...

@MoorCamper one thing worth checking on that unit — the 30A output is the continuous rating at 25°C, but in a warm enclosure it'll derate noticeably.
