@RetiredChef worth checking if your Multiplus firmware is current — there was a batch of charge profile quirks that got sorted in later versions.

@VoltVicky my shepherd's hut is basically a tiny power station at this point — Victron inverter, Fogstar lithium bank, the works — yet I'm still handing over £60-odd a month to the grid for the...

BordersOffGrid | 1,204 posts @ExSquaddie49 @HappyWelder @DownsCruiser — all solid points already covered, so I'll add the thing nobody mentions until it's too late: Check your cable runs aren't...
My Multiplus II 12/3000 has been throwing a wobbly every time I crank up the compressor on my roof-mounted Dometic — turns out 300Ah of AGM simply doesn't have the grunt to handle that inrush...
@RelayBuild same pain here — my Victron/Fogstar setup on the main house means actual consumption is negligible but the standing charge bill is almost comical at this point. Seriously considering...

Watching this thread with interest. The MultiPlus 12/1200 pulls serious current at full load — we're talking 100A+ on the battery side — so even slightly undersized cable or a terminal that's only...
Got a bit of a head-scratcher here and hoping someone can save me from going down another rabbit hole. Running a SmartSolar 100/30 on my static caravan setup — currently charging a pair of 100Ah...

@CamperCarl pure sine or go home — my Victron Multiplus and a decent Fogstar battery sorted this exact nightmare in the van, transformer's been whisper-quiet ever since.
@BlownFuse good shout on the status LED — easy to overlook that. One thing worth adding: if you're running VictronConnect via Bluetooth while driving (passenger can monitor it), you can actually...

@MarineGaz one thing nobody's mentioned yet — have you checked whether your MPPT is actually hitting absorption at all before dropping to float?

Had a similar head-scratcher when I was commissioning the setup in my shepherd's hut last spring. I'm running a Victron Multi RS paired with a Nucleo GX, and when I first powered everything up,...
Has anyone else had issues with these all-in-one units struggling to charge at the rated capacity? I've been looking at a similar setup and I'm wondering if the MPPT controller built into these...
Had almost the exact same drama on my narrowboat last spring. The Multiplus I had at the time was a 12/1600 and every time the missus nuked her morning porridge it would throw a wobbly — that...

@FormerTeacher61 spent three weeks convinced my Multiplus-II was possessed before realising I'd set the Dynamic Cut-off curve for a lithium bank on what was decidedly a lead-acid situation — the...
Good shout on the cable run @GazAllen — though I'd also look at the connection quality at both ends before assuming it's length alone. On my narrowboat I had cycling behaviour that turned out to...
OldSailor | 2,341 posts | ⚙️ Off-Grid Obsessive Dollar pricing on a UK forum is your first red flag — the landed cost with import duty, VAT, and inevitable courier surcharge will cheerfully devour...

@ForestDaz yeah the support thing is a real headache with anything not sold through UK distributors. Honestly for a shepherd's hut or travel trailer setup I'd just go Victron MultiPlus — yes it...
@SomersetNomad really want to understand the vapour control point properly before I make any decisions — are we talking a specific membrane product, or is it more about the choice of insulation...

@PanelRoger one thing I haven't seen mentioned yet — make sure you've set Assistant switch 3 correctly in VEConfigure (or VictronConnect if you're using the newer firmware).
@BordersExplorer interesting timing on this thread — I've been through the brand-switching ritual myself on both my static and the motorhome, and the pattern is always identical: Ageing inverter...
