@Titch the Bluetooth point is fair but I'm actually wondering if the 75/15 is even enough for certain setups rather than overkill — my concern is more about headroom.
@Fiona1974 mate, the Multi RS Solar's Voc limit will humble you faster than a low bridge on the Oxford Canal 🚢
@NicolaTaylor72 The BAT512130620 uses the standard M8 circular connector for the BMS comms — same pinout as the rest of the Smart Battery range.

Been through this exact saga with my motorhome stack last February. What sorted it for me was patience more than anything clever — I ran three full discharge-to-near-empty cycles back-to-back...

@VivaroWanderer just going through something similar on my narrowboat right now — added a second Fogstar 100Ah AGM alongside my existing one (different age, which I now realise was a mistake after...

@CarlWalker welcome to the forum — good detailed first post, exactly the kind of thing that helps everyone. One thing worth checking that often gets missed after a network change: the MQTT broker...
@48VQueen pretty much, yeah. Though to be fair there's a workaround — if you've got Node-RED on the Cerbo you can poll the VRM API or scrape the display value via dbus directly. On my boat setup I...
@HMK_Sparks two years in is actually the interesting inflection point — that's roughly when you've got enough data to know whether the Victron ecosystem is genuinely working for you or whether...

Yeah this is a France-specific cert so a bit niche for this forum tbh — but worth knowing about if you're buying secondhand kit off French marketplaces, since some Victron gear over there gets...
@Boycie25 that 0.9mA figure is reassuring but I'm curious — does that change meaningfully when it's actively logging or syncing via Bluetooth?
@T6Project yeah the 240V thing is the first thing I'd be checking too. Had an ECO-WORTHY panel kit years back, the specs on the listing were...

Great thread! I went down a slightly different route and set up Node-RED on my Pi 4 alongside InfluxDB and Grafana for the visualisation side.
@JimWilson the Bluetooth monitoring alone justifies the "overkill" tax for me — knowing exactly what my panels are doing from inside my tiny house while it's hammering down outside is...

@NicolaTaylor72 Which M8 cable length are you after? I had exactly this faff on my motorhome build — the Victron M8 data cable (ASS030560200 is the 2m one) was surprisingly hard to source locally.

@CarlWalker this rings a bell from when I rewired my own narrowboat setup last autumn. After a firmware jump on Venus OS Large, my Cerbo GX completely lost its head about anything on the CAN-bus —...

MistyTinker | 1,204 posts One thing nobody's mentioned yet — if you're planning any off-grid electrical setup in the stone building, that thermal mass @JimWilson mentions works against you in...

Done exactly this with my shepherd's hut build 😬 Spent ages spec-ing out the Multi RS Solar then nearly bought a job lot of panels without checking the Voc properly.
@ThistleVicky the "doesn't complain" part is doing a lot of work there — mine absolutely does complain, just via email alerts at 2am when the Multiplus throws a wobble. Got a Pi 4 doing...
@VoltJohn had exact same setup last winter — Multiplus II 3kVA with a Fogstar Drift 48V. What fixed mine was tightening up the battery communication settings in VE.Config.
Hey @MoorSeeker, that's a classic MPPT hunting issue — your controller is losing the maximum power point and can't lock back on properly.
