Has anyone actually pulled the trigger on one of these? I've been eyeing them up for my cabin setup and the spec sheet looks decent on paper — 314Ah at 48V is a serious chunk of storage for the...

Been mulling this one over for a while and thought I'd throw it out here. Running a Victron MultiPlus-II 48/5000 in my setup — Cerbo GX, Fogstar Drift lithium bank, ET340 on the grid tie — and...
@OffGridHamish Had exactly this frustration on the narrowboat. DESS doesn't expose its reasoning natively, but there's a practical workaround worth trying. Pull the MQTT data from the Cerbo and...
Done the same swap on my motorhome and the charger drama is basically a rite of passage at this point.

@OllieRoss74 one thing nobody's explicitly spelled out yet — the BMV 712's negative sense wire (the small one, not the main shunt cable) needs to connect to the battery negative side of the shunt,...
@JimKelly one thing nobody's mentioned yet — check your absorption time setting isn't capped too low.
FormerCop | Posts: 1,203 @AlanWard — everyone's covered the sag angle, so I'll add the thing nobody mentions: check your actual low voltage disconnect setting in VictronConnect. On 24V systems the...
Interesting one this — I've been following a similar thread elsewhere and wanted to bring it here because I reckon a few of us running Victron setups without a battery bank will have hit...
@MarshLover interesting you got nothing conclusive — I had almost identical results when I scoped mine on the shepherd's hut.

Been thinking about this a lot lately with my garden office setup. Running a Victron SmartSolar 100/20 and honestly even on decent summer days I'm nowhere near rated output from my single panel.
Been having a similar issue with mine on the boat. The Orion XS 50A is set up charging my leisure bank from the starter battery, and I've noticed it consistently stops a few percent short of what...

Been scratching my head over this one for a while now and figured someone here would know the answer. I've got a static caravan on a rural plot — fully off-grid with a Victron Multiplus II at the...

Great thread, this. @Wez1961's SmartShunt approach is the right direction — I'd add that you can feed both shunts into the Cerbo via VE.Direct and then use the 'has DC system' option in the...
@Stu1991 the batteryless approach is genuinely fascinating but I'd want to see the panel data before calling it viable. The fundamental problem isn't cloud cover gaps — it's the rate of change.
@BoatMark worth clarifying what Ekrono expects at the application level when there's no inverter node present — in my tiny house setup I ran it meters-only for about four months before adding a...

@TracyMitchell curious whether you're also seeing this affect your charge acceptance rates? I've been monitoring my setup (garden office system, Fogstar Drift LiFePO4) and noticed my BMS is...
@PartnerNomad I actually did scope mine briefly after a similar dropout on my shepherd's hut setup — nothing conclusive but there was definitely some noise around the transition.

Been wondering whether to add this to my cabin setup for a while. Currently just relying on the Victron app via Bluetooth which is fine day-to-day, but I lose all historical data if I don't...
Really useful thread this. To add to what @LDVWanderer and @ShedGenius have touched on — don't overlook the Victron GX portal side of things if you go the smart shunt route.
@OffGridHamish this is exactly the kind of rabbit hole I've been eyeing up. Quick question though — what are you getting out of it in terms of actual voltage and current at useful wind speeds?
