Been seeing something odd with my Cerbo GX since updating to 3.81 and wondered if anyone else has clocked this. Running a MultiPlus-II 48/5000 in the shepherd's hut — got a Victron MPPT doing most...
Anyone else had the joy of swapping battery brands mid-setup and discovering your inverter has suddenly developed a personality disorder? Switched from my original AGM bank to Fogstar Drift...
Really interested in this topic as it's something I've been wrestling with on my boat setup. Running a Victron MPPT and Cerbo GX alongside a third-party inverter/charger, and the VRM energy flow...
@Chopper54 six years is genuinely impressive but the real story is what the battery bank looks like after that runtime.
@ExSquaddie a "review" — right, like when your boss "reviews" your performance and somehow you end up with more work and less pay.

Interesting one – I can add another data point here. Same pattern on my off-grid cabin setup, Cerbo GX on v3.81 this time rather than v3.79, so it's persisted across that update at least.
@HazelSoul @Curly38 @CopperWelder the pasty brigade grows 😄 One thing nobody seems to mention is thermal mass on a budget — even just a few flagstones or a slate floor can make a noticeable...
Hey @CraigCross, yes been through something similar when a mate upgraded his setup. Worth double-checking you've got the Multi RS firmware fully up to date before anything else — there were some...
@FormerMariner24 on my narrowboat I've run the MP2 in charger-only mode (switch position 1) for periods when I'm hooked up to shore power and don't need inversion.
@JasonMoore @LutonLife is right about induction motors being the wrong choice, but worth adding — permanent magnet motors from older front-loaders are the real prize.

What's your cable run length from panels to MPPT? Had this exact issue on my motorhome last year — turns out my 4mm² cable was way too thin for the run I had, voltage drop was brutal and the...

@SaltyRanger is on the right track but there's a bit more to it than pure cell chemistry. The JK specifically has a known quirk where the NTC temperature sensor — that little black blob usually...
@EcoFlowMaster closer than you think — the BMV-712 is a coulomb counter (integrating current over time), whilst your BMS is typically doing voltage-based SOC estimation, and they drift apart for...

@BordersExplorer that 58.4V ceiling is worth keeping in mind if you're planning to push absorption on a LiFePO4 pack — most 16S configs sit comfortably under it but worth double-checking your BMS...
@RustySkipper purely cosmetic as far as I can tell — my VRM data is spot-on, it's just that "alternator" label sitting there judging me every time I glance at the dashboard while I'm...

@HazelSoul @CopperWelder @Curly38 haha the pasty analogy is doing the rounds now 😄 Seriously though, for a 20m² cabin the single biggest difference I found was sorting the roof first before...

Six years of Victron keeping 40 people fed with electrons is basically the brand's brochure writing itself — my shepherds hut system is only responsible for keeping me in hot tea and nobody's...
Good points all round, and @ExSquaddie's experience rings true — shared banks are where monitoring becomes absolutely critical rather than just nice-to-have. Running my motorhome setup I've...
Has anyone actually done this with a single Victron Multiplus feeding both locations via separate circuits, rather than two inverters?

@BatteryAlan the fundamental issue is that Victron's split-phase implementation relies on precise phase synchronisation via the VE.Bus protocol — both units need to agree on timing and load...
