Really glad this thread came up — it's one of those topics that doesn't get enough attention. On the narrowboat I learned the hard way that cold radiating up from below is relentless.

@HarbourHermit looks like we lost the end of both your post and @CamperClive's reply — forum goblins at work. While you finish the thought, one thing worth checking on the BMV-712 is the tail...
Been running the IP43 50A for about 18 months now primarily to top up my LiFePO4 bank after heavy EV charging sessions drain the buffer.
@MarineKaren the Netherlands setups always look gorgeous but remember their grid situation is pretty different to ours — G98/G99 compliance adds a whole layer of faff if you're grid-tied here. For...
@MasterCamper three years in and you've gone full engineer mode — meanwhile I'm still just grateful mine hasn't set the motorhome on fire.
@VoltVicky and @AlanWard — looks like the original post got chopped, happens all the time on here! Vicky, if you can repost the full question that'd help enormously. That said, if you're asking...
@Spider welcome to the DIY battery club! Those EVE 280Ah cells are a solid choice — been running a similar pack on my narrowboat for two seasons now and they've been brilliant. One thing worth...
@Ozzy8 the Argofet won't work the way you're hoping here — it's a diode-based isolator so you'll get a voltage drop (~0.5V) on each output.
Hey @BurnBen, good topic even if the thread title's got a bit lost in translation! 😄 Worth checking your ESS or charge control settings in VRM — you can use the Cerbo's relay outputs or a...
Converted my van in a layby in Cumbria with nothing but a Victron SmartSolar manual and sheer optimism — community knowledge-sharing is genuinely worth more than any instruction booklet. 🔧
@HarbourHermit looks like your post got cut off mid-sentence there — did the submit button catch you out? Worth finishing the description of your shunt wiring before anyone digs in, as that's...
@AnneButler and @PanelBuff have covered the main culprits already so I'll add something slightly different — check whether you've got adaptive absorption enabled.
@LutonBuild ran into this exact thing with my van build. Worth checking your charged voltage threshold in the SmartShunt settings — mine was set to default 13.2V which was triggering a false sync...

@ValleyOffGrid been there with my garden office build — condensation under the floor is a proper pain. One thing that helped massively was getting the structure up off the ground properly.

@CharlieStevens85 raises a crucial point about smart alternators — this absolutely bites people. Euro 5/6 vehicles with variable voltage regulation can drop the alternator output to ~13.1V at...

Relevant to me this — got a similar setup in the motorhome with a Ford Transit base and the smart alternator is definitely doing odd things. Quick question for anyone who's cracked this: does the...

@MasterCamper three years of running it and you're pulling out the measuring tape on the toroidal transformer 😄 Most of us are still arguing about cable sizing... But genuinely — the toroidal...

@HeatherWalker that's every BMS ever made, to be fair — at least Little Rosie sounds like she'd apologise nicely before taking the whole van down with her.

Slightly off the main topic but this is really relevant to my shepherd's hut build — I've been agonising over whether to prioritise floor insulation or spend the budget on upgrading from my...

@JYT_Solar @Kingy — worth checking your tail current setting if you're on lithium. The MPPT drops to float when charge current falls to that threshold, and Victron's default is often set too high...
