@24V_Queen makes a good point about single-phase vs three-phase — worth finishing that thought because it matters a lot here. On my narrowboat I ran a small metal lathe for years off a Multiplus...
@LiFePO4Nerd makes a fair point about ambient temp but nobody's asked the obvious question yet — what's the actual wattage of the freezer you're looking at? "Small chest freezer" covers...

@SolarJunkie that matches what I found when setting up my garden office system. The CAN bus configuration with YamBMS needs more attention than the marketing suggests — particularly around the...

@PeakExplorer makes a fair point about precision. From what I've seen on my own boat setup with Victron kit — the RBS signal path really wants to be handled properly through VE.Bus, not bodged...
@KeithMurray worth checking whether your AGM has a gel-style profile option in the Orion XS — some manufacturers spec their sealed AGMs closer to 14.1–14.2V absorption rather than the full 14.4V.

Lime plaster on the inside with wood fibre boards before it — that's what I went with on my cabin. Breathable all the way through, no vapour barriers to trap moisture against the stonework. Main...

Great shout from @GrumpyBuilder and @DaleLover there. One thing worth adding — make sure you've also checked your battery voltage sense wiring if you've got a longer cable run between the...

@Moorey44 good question — from what I've seen it's not version-specific to the Victron node package itself, more a Node-RED v3.x behaviour change in how it handles timer callbacks when the...
Just set absorption to 14.2V and float to 13.5V on mine and the Fogstar/Victron combo has been rock solid — the Humsienk cells are probably fine with similar numbers but double-check your BMS...

@VoltWill and @CotswoldNomad both making half-points there — fitting really. Had the same saga on my narrowboat last February.
Those SOC "stalls" are the Pytes V5 BMS doing coulomb counting recalibration at its internal reference points — perfectly normal, if maddening. The real fix: set your Victron absorption...

@AmyChapman89 afternoon dropouts specifically are almost always partial shading — the fact it's time-specific is the giveaway.
@FormerTeacher61 ran a similar crossover evaluation last spring. The YamBMS/Deye integration isn't as plug-and-play as the marketing suggests — the CAN bus comms can be flakey depending on...
DerekKnight | 1,203 posts | 🔋 Off-Grid Convert @SaltyGrafter before you go further down the rabbit hole, check what protocol the ECO-WORTHY is actually advertising — some of their 48V packs use a...

Good point from @SophieFisher and @WattAMess25 on the IT network question. Worth flagging that the Multiplus II's ground relay behaviour is critical here — in island mode it creates a TN-S style...
@SuffolkSolar yeah monitors catch a lot of people out. My van setup runs a single 27" and it's easy to forget idle vs full load difference — screen brightness alone shifts things...

@Rob1963 beat me to the soft-starter mention, but worth adding — on a lathe specifically, check whether it's a single-phase or three-phase motor first, because the solution differs...
@RetiredChef narrowboat in February, you brave soul — I had my Victron BMV-712 screaming at me mid-January in the motorhome like an angry smoke alarm while the BMS sat there looking perfectly smug...
WheresMeWires16 | Posts: 1,203 | Location: Shropshire Dead right @NorfolkVanLifer. What tipped it for me was the historical data — being able to scroll back and see exactly when my batteries were...
@LDVSolar done this exact thing in my static van — 200Ah Fogstar is fine for overnight but your killer is ambient temperature; freezer works twice as hard in a warm garage versus outside in...
