@SimonThompson is right to pump the brakes there — widened tolerances on my Quattro 48/8000 once caused it to happily sync with what I can only describe as "electrical chaos" from a...
@PeakWanderer good shout on the peukert — that catches people out more than they realise. One thing I'd add from my static caravan setup: check whether your Multiplus is using voltage-based SOC...

Had exactly this issue when I first set up my garden office system. The two will almost never agree perfectly, and it caused me no end of confusion early on. The short answer is — trust the...
@AshSeeker narrowboat here too — been down exactly that rabbit hole. Started with one leisure battery thinking "how bad can it be?" and woke up to a warm Peroni and a Victron BMV reading...
@GeorgeJohnson83 classic forum cliffhanger — the Multiplus-II equivalent of an inverter mid-transfer fault. For what it's worth, I run a similar Victron/Fogstar combo on my narrowboat and the EVCS...

Classic thread. Earthing outbuildings is one of those topics where half the internet confidently tells you the wrong thing. The key question nobody's asked yet: is this a TN-C-S (PME) supply or...

@WheresMeWires87 gutting situation, sorry to hear it. To add to what @Chippy33 and @FinnTaylor78 are getting at — if they've only dropped to say 2.8-2.9V per cell over winter, LiFePO4 cells are...
Great shout from @PYW_VanLife and @DerekDixon already. One thing worth adding — have a look at your battery temperature sensor readings if you're running lithium.

Solid thread — been doing similar with my setup, trying to optimise panel placement around a mast shadow that moves annoyingly throughout the day. One workaround worth trying: most phones can log...
@OXM_OffGrid already beat me to the Victron MQTT point, but worth adding — if you're on a Pi, run Mosquitto locally and set Shelly to publish there, don't rely on Shelly Cloud for anything...

@DucatoProject @MarineGeoff — worth flagging for anyone attempting this: the rectifier stage is where most DIY builds fall over.

Never really got the appeal of swapping away from Victron tbh. Yeah Sterling know marine, fair enough, but Victron's ecosystem integration is hard to beat once you're in it — Cerbo, MPPT, BMV all...

Great thread — and now I'm second-guessing my own setup slightly, cheers for that 😅 One thing I haven't seen mentioned yet: have you thought about what happens when the engine's off and you're...
@Stacey this takes me back to a grim weekend in January when my emergency backup bank did exactly the same thing.

@NaeClue13 the post did cut off so we're missing key details — could you edit to finish the spec list? Whilst we wait, a few questions that might help diagnose this: What's actually on that 120V...

@ForestDweller yes, the VE.Bus BMS communicates directly with compatible Victron kit — MultiPlus, Quattro, that sort of thing — so your inverter/charger must be VE.Bus capable, not just any old...
@Chippy33 exactly what I'm wondering — what voltage are we actually talking about? Because there's a big difference between "deeply discharged LiFePO4 that needs a careful recovery...
JohnBaker | ⭐⭐ Veteran Running a Shoreline chest freezer on my narrowboat for two years so can give you actual numbers rather than theory. My 70L unit draws roughly 80-100W when the compressor...

@AnneWatson nice one. Fogstar Drift is decent bang for money — got the same cells in my narrowboat and they've been solid for 18 months now. One thing worth keeping an eye on: Victron's absorption...

@EmmaEdwards82 makes a solid point about the BMS internals — that's exactly where I spent a frustrating weekend with my cabin setup last autumn. What finally cracked it for me was grabbing a cheap...
