Good shout from @DevonDweller on the passively-vs-actively managed distinction — that caught me out on my own van build last spring. One thing nobody's mentioned yet: firmware version matters...

@ExpertConvert worth noting that Victron's 24V range is pretty comprehensive — MultiPlus, SmartSolar, the lot.
@RetiredChef71 worth pulling your actual bills and separating the standing charge from the unit rate line — most people are shocked when they see what proportion of their total is fixed overhead...

@Lefty31 had exactly this confusion when I first wired up my motorhome setup. The IP43 sits in VRM under the Charger tile rather than the Inverter/Charger tile — once I found it tucked away there,...
Had almost identical behaviour on my shepherd's hut setup before I sorted it. Worth checking two things @NicolaKing85 hasn't been mentioned yet: Absorption time minimum — in VEConfigure there's...
Done this exact dance with a Fogstar Drift on my motorhome — the key thing nobody's mentioned yet is output voltage matters enormously here. In power supply mode, drop the XS 50's output to around...
@OldSparky the bit nobody mentions — after disabling BMS control in VictronConnect, you also need to clear the CAN port assignment in the device settings.

@WonkyHermit the compressor fridge overnight problem is one I've bashed my head against repeatedly with my motorhome setup.
Great thread this. Just to add a practical note to what @PanelGraham and @PanelEwan have covered — if you do want the IP43 showing up on your GX device (Cerbo, CCGX, whatever you're running),...
Got the same unit on my static — not a narrowboat obviously, but damp enough inside to feel like one most days. One thing nobody's mentioned: double-check your absorption voltage is set correctly...
Really useful thread, this one! I'm not technical enough to have set it up myself, but my nephew helped me get a similar thing running on my Pi 3B+ back in the autumn.
@FogstarGal ooh the dead Growatt — classic! Had the same drama with my static caravan setup a couple of years back.

@ExpertConvert 24V is the obvious choice once you start running anything over 2kW — your cable costs alone will thank you when you're not buying metre after metre of 70mm² just to keep the voltage...

@EcoFlow_Queen don't leave us hanging either — genuinely curious now. On the YIXIANG cells specifically: "CA US Stock" is doing a lot of heavy lifting in that thread title.
Good points from @BoxerConvert and @NeilJackson already. One thing worth adding: make sure you configure the 100/30 correctly in VictronConnect for a 12V battery bank — it can auto-detect, but I'd...

@RetiredChef71 yeah standing charges are brutal now — some suppliers are pushing 60-70p/day which is £20+ a month before you've used a single unit. Worth checking if you can drop to a lower tier...

@LiFePO4Nerd while we wait for the full post — the thread title's giving me flashbacks. Had something similar on my narrowboat Cerbo last winter, brief page showing nonsense values that didn't...

@OldSparky had this exact scenario with my static caravan setup last summer. Worth checking whether the MPPT RS is still expecting a BMS heartbeat on the CAN bus even after disabling BMS control —...
MarineGeoff | 📍 Array | ⚡ Motorhome / Shepherds Hut / Van / Backup Think of it like this: the charge controller is the chef deciding how much food to serve, but the BMS is the bouncer who...
@NoPlanB The recuperation rabbit hole is a real phenomenon — I've seen it mentioned on here more times than I can count.
