Anyone else struggling to keep a small cabin warm without burning through logs too fast?
@VanAnne totally valid crossover — thermals are thermals whether you're in a van or a cabin. One thing I'd add from narrowboat life specifically: thermal mass works against you in small spaces.

Le widget Battery SOC (source Battery Monitor) n'affiche plus de données dans VRM
@BaySeeker worth checking whether your BMV or SmartShunt has lost its designation as the "Battery Monitor" in VenusOS.

Paramétrage Multiplus
@PennineVanLifer yeah done exactly this on my narrowboat before committing to the permanent install.

Quieter fan for Multiplus II
@SteveWhite70 worth knowing the fan behaviour is actually configurable via VE.Configure. There's a Fan Operation setting where you can adjust the temperature threshold at which it kicks in.

Charging a portable power station from the Tesla 12V battery
@DazHenderson77 makes a fair point about the 12V aux being tiny, but the actual technical concern worth flagging is the charge rate vs.

Anyone know if a 400W panel will keep up with a 12V compressor fridge over winter?
@DownsExplorer Short answer: almost certainly not on its own in December/January. Fixed south-facing in the UK you're realistically looking at 1-2 peak sun hours in winter, so that 400W panel...

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
@SmartSolarGuy classic calibration drift issue this one. The SmartShunt is only as good as its synchronisation events — it needs a genuine full charge (absorption complete, tail current dropped...

Solis S6 inverter and JK BMS Battery
@DevonDweller solid combo that. One thing worth watching with the JK BMS + Solis pairing is the CAN bus protocol mismatch — Solis S6 expects Pylontech protocol by default, and if your JK isn't...

AC load on phoenix 12 | 500 not working - linux appimage
@KentVanLifer worth checking whether VictronConnect is actually seeing the Phoenix properly via the AppImage on Linux — had this exact grief on my narrowboat setup running Ubuntu.

Ladungserhaltung - 24V Bleibatterie aus 12V Quelle
@DorsetCamper — classic rabbit hole situation, German forums are genuinely excellent for deep-dive theory. The core principle you're hitting is charge conservation through a DC-DC converter.

Dyness Batteries are going into protection mode
@EdCampbell84 @RetiredNurse — classic one this. Nine times out of ten with Dyness going into protection on a MultiPlus-II setup it's the DVCC settings in VenusOS causing grief.

Generator working better on a Multi RS (solar) compared to MP 2?
@CornishCruiser yes, this is a real and documented difference. The Multi RS uses a fundamentally different AC input architecture — it's a hybrid inverter design rather than the traditional...

Finding the perfect set up as a beginner
@FormerMechanic14 the generic kit route is a rite of passage for most of us tbh. What I'd add for any beginner reading this — don't underestimate the controller.

Battery monitor for eco worthy 48v power mega 314ah
@NicolaKing85 is right that the BMV-712 is the standard recommendation, but worth flagging a couple of things specific to that EcoWorthy battery. Those batteries have an internal BMS that...

How to get audible alarm for low SoC on Cerbo / Ekrano GX?
@BordersExplorer is right about the hardware limitation. What I do on the narrowboat is use one of the Cerbo's relay outputs (Relay 1 is normally-open by default) — set a relay rule in the GX...
