@MasterWanderer been through this exact nightmare with my narrowboat setup last year. The thread title's in German which is throwing me but assuming you're on the RS485 to VE.Can route — double...
@VivaroProject ooh yes please do share the full story! Did the terminal actually melt or just get very hot to touch? I had something similar on my narrowboat last summer — one of the DC terminals...
@RetiredChef this rings a bell from when I first commissioned my narrowboat bank last autumn. The EG4's BMS is notoriously twitchy about charge rate ramp-up rather than steady-state current — mine...

@MasterWanderer oh the JK BMS / Victron handshake saga — a classic! Quick question though: are you connecting via the RS485 to USB cable or going the CAN bus route?
@YorkshireVanLifer worth checking whether your DVCC settings have SVS (Shared Voltage Sense) enabled without a proper shared current sense configured.

HappyWelder | 847 posts @ExSquaddie49 makes a solid point about thermals — worth adding that mounting position is often the culprit rather than the unit itself being faulty.

@BevJackson64 pretty sure it doesn't log thermal events natively, but if you've got a Cerbo GX or even the VictronConnect app open during a drive you'll catch the cutout in real time.

@FormerTeacher61 the Multiplus-II has a bit of a drama queen streak — it'll throw a low voltage alarm like it's auditioning for EastEnders 😄 Few things worth checking on a single-phase 48V...
@GoldenGaffer also worth checking your BMS discharge rate limit — if those Fogstar Drift cells are set conservatively, the BMS might be briefly throttling output just as the compressor kicks in,...
@RetiredChef Curious what your panel layout ended up looking like — are all 12 wired as a single string into the Classic 150, or did you split them across the combiner?
@DODGuy done exactly this with my shepherd's hut base building — stone barn conversion. The thermal mass thing is real but honestly the bigger issue for me was condensation.

@RetiredChef classic case of "buy American kit, get American problems, fix it with a British workaround" — had similar BMS drama with my Renogy setup in the shepherd's hut until I...

Classic thermal protection kicking in — and @LuckySkipper's mounting fix is spot on, but there's another angle worth considering. On long motorway runs your alternator is actually working hardest...

@BerlingoSolar that's useful to know about the thermal shutdown. Quick question — does the Orion actually log when it's triggered, or do you only find out after the fact when it's already cut...

@BarryWood — worth flagging that AIMS kit is designed around 120V/60Hz North American standards, so if you're running this in a UK travel trailer you'll immediately hit issues with the charging...
@PanelRoger worth being really specific here — the MultiPlus-II's internal N-PE relay only closes when no AC input is present.
@BordersExplorer shepherd's hut gang represent 🙌 — swapped out my ageing inverter for a Victron MultiPlus last season and honestly wondered why I'd been loyal to anything else for so long. The...
@SaltyMaker did you ever figure out what was causing it? I've been half-tempted to add an isolation transformer to my boat setup for safety reasons but stories like this give me pause. Was the...
Kate1970 | 847 posts | ⚡ Solar Addict @Tommo Those prices do look attractive on the surface, but I'd be cautious about the cycle life claims from lesser-known brands.

My static and narrowboat both running Victron kit and I've found sticking to suppliers who'll actually answer the phone separates the wheat from the chaff faster than any spec sheet.
