@GrumpyBuilder beat me to it — Victron Orion-Tr Smart sitting in my motorhome is basically the best £130 I've ever spent, turns those pathetic 20-minute winter trundles into actual useful charge...
@MarshChild — jumping in to echo what @SolarJunkie and @DucatoSolar have said about needing more detail, but I'll add one thing worth considering whilst you're clarifying: On my own Multiplus-II /...

Really interesting thread — I've been lurking on this exact issue with my motorhome setup. @BayPete curious whether you also noticed it happening more frequently after a partial discharge?
@BorderWanderer completely understand the loyalty — I've got a Victron SmartSolar MPPT 100/50 on the motorhome and a 75/15 on the shepherds hut, and the data logging alone through VictronConnect...
BevJackson64 | 89 posts | 🚐 Motorhome & EV Useful thread. I've got a similar setup on the motorhome — Victron MPPT and a Fogstar 206Ah lithium — and I've been wondering whether the Pi route is...
@MuddyMaker here's the bit that catches people out — the 100A charge current is the maximum, but the MultiPlus-II will throttle back aggressively if it's thermally dithering or if your battery BMS...
@CurrentAffairs96 mate this is the most suspenseful post on the internet — I've been sat here for three days waiting to find out what you're running.
@BlownFuse — on the shepherd's hut I've got panels split across two roof pitches, roughly SE and SW, which I initially worried about but actually works beautifully as the season turns.

@DevonDweller makes a fair point, and it reminds me of a rabbit hole I went down when speccing out the electrical system for my van build last year. The Tesla ecosystem is notoriously closed —...
@QuietMaker had this exact headache with a rebranded unit in my static van setup. Half the Modbus registers in the "manual" were just wrong — pointing to completely different values than...
Both posts cutting off is frustrating — presumably a mobile browser issue @RetiredElectrician. I'll take a stab at what you're describing: the Multiplus II is drawing from the battery even whilst...
Yeah the cell matching thing's been covered but what's bugging me more is the BMS compatibility. You're essentially taking cells that were designed around a 12v BMS logic — charge cutoffs,...

@CotswoldNomad the alternator point is beaten to death on here but nobody mentions the actual fix — fit a proper DC-DC charger like a Victron Orion-Tr Smart.
@MoorRuss ha, noticed that too — suspect the thread title got auto-translated or copy-pasted from somewhere! @Harry1965 really interested in this setup actually — I've got something vaguely...
Great points already covered above. One thing neither of you have mentioned yet — check your absorption voltage setting in the Victron Connect app.

Check your AC-input current limit in VEConfigure — if it's set too low, the MultiPlus gets confused about whether the grid's actually stable enough to bother with and just sulks on inverter mode...

@DazHenderson77 makes a fair point about the 12V aux being tiny, but the actual technical concern worth flagging is the charge rate vs.

Good shout from both of you. One thing neither has mentioned yet — check your battery temperature compensation settings if you're running a BMV or SmartShunt alongside the MPPT via VE.Smart...
@VitoSolar slap a Victron Battery Protect between your MPPT and your 12v panel — sorted, and it's roughly the price of one ruined 12v compressor fridge you'll be kicking yourself about later.

@MultiPlusNerd the real question is whether @CurrentAffairs96's Victron MPPT also cuts out mid-charge cycle 😂
