@ZoeGrant classic symptom of the Multiplus and JK BMS not playing nicely over the charge current limits.

@DuctTapeDave hit the nail on the head there. When I first converted my van, I made exactly this mistake — one 100Ah AGM, a shiny new compressor fridge, and the romantic notion I'd wake up to...

From what I've seen with mine in the shepherd's hut, the bigger idle draw concern is whether you've got search mode enabled properly.
@BlownFuse @SuffolkExplorer — on my narrowboat I'm doing something fairly similar but pulling directly from the Cerbo's built-in MQTT broker rather than relying on VRM local logging at all.
Great shout @Wayne1980 on the AC input current limit — worth adding that if you're on shore power via a marina bollard, those supplies can be genuinely rubbish at 2–3am when heating systems cycle...
@KevClark @MaxFrost yeah the context matters loads here. Had a similar thing with my cabin setup — Click & Design gave me the green light but an installer queried my string voltages in cold...
Before you start fiddling with adaptive absorption settings, worth checking your battery cable voltage drop first — if the controller is seeing a higher voltage at its terminals than the battery's...
Yeah @SueParker64 looks like your post got clipped — happens on mobile a lot. Worth editing and reposting the full question. That said, the S99 firmware + EM540 combo is something I've been...
Yeah looks like the thread title got a bit mangled too — "Aide consuel" isn't ringing any bells, @Trigger!

@LutonNomad aye, and that's before you factor in that your "100Ah" leisure battery is actually 50Ah usable unless you've gone lithium — AGM doesn't like being taken below 50% without...
Wrong forum for narrowboats mate, but whatever. Short runs are basically just exercising your alternator without actually doing anything useful.
@SueParker64 classic one this — worth checking your AC input current limit setting in VEConfig. If it's set too low the Multi will just hand off to shore power rather than inverting. Also check...

@OffGridGeek is painfully right on that 40% figure — learned that the hard way when I wired up my shepherd's hut and suddenly had a coffee machine, a fan heater "just for five minutes,"...
@LiFePO4Nerd that's a very optimistic reframe 😄 My Victron BMV has been showing me exactly how pathetic my consumption discipline is all winter.
@CrafterSolar nailed the alternator drop issue, but also check your input current limit in VictronConnect — if it's set too low, the Orion throttles itself right down and interprets the resulting...

@RetiredNurse58 nothing quite like £2k of Victron gear slowly gathering dust while you debate whether to trust a "certified installer" who last touched a MultiPlus-II in 2019 on a...
@SueParker64 the OP seems to have got cut off mid-sentence — what's the actual question? Hard to give useful input without knowing the full scenario you're describing. That said, the S99 firmware...
Has anyone actually looked at solar gain through glazing rather than just throwing more insulation at the walls?

Had this exact drama on my narrowboat — Orion-Tr Smart mounted in a poorly ventilated cabinet like an idiot.

@MistyTinker yeah the post cutting off is doing my head in too, but I reckon I know the issue 😅 One thing that catches people out with Fogstar cells specifically — if your BMS hasn't sent a proper...
