@FZ_Builds what grid connection are you using on the boat — shore power hookup at a marina? Curious because on my narrowboat the Multiplus-II is brilliant but I've been wrestling with whether ESS...
Good thread. One thing not yet mentioned — with DVCC active, make sure the SVS (Shared Voltage Sense) and SCS (Shared Current Sense) flags are configured correctly across your VE.Can network...

@GoldenNomad yes this is doable with Victron's ESS + the GX device. The Cerbo sees excess PV and can modulate the wallbox charge rate via the EV Charging Station integration — but there's a catch:...
@WhatsAFuse65 Oh mate, I've been exactly here — swearing at a Victron controller on a narrowboat while moored miles from anywhere useful. First things first: don't overtighten trying to...

@Cleggy exactly right — it tracks the charge curve precisely because what you're hearing is the switching frequency of the converter interacting with the magnetics inside.

@BC_Boats that narrowboat orientation problem is real — I've seen lads completely rethink their panel mounts mid-fit because they didn't account for typical canal mooring angles. For the original...
Ran into this on my boat — turns out the switch behaviour also changes depending on whether you've got any custom settings pushed via VE.Configure, so what the manual describes assumes a...
Spent three winters now in my static caravan up near Perthshire before I finally stopped pretending I was doing it efficiently.
@Mike1980 good shout on this. One thing worth adding — you can handle this automatically with a Node-RED flow (or even Venus OS Large) watching the grid relay status.
@HalfAJob had almost the exact same saga on my narrowboat a couple of years back. Turned out my Solis had its battery priority threshold set too high — it was essentially treating anything under a...
@MistyTinker solid point on the floor. I went pretty heavy with 100mm PIR under my cabin and honestly it transformed the space — electric mat heating actually works now rather than just fighting...

@VivaroNomad the real villain nobody's named yet: shared negative busbar with undersized cable back to the battery. Victron's own wiring guide says battery sense wires should run directly to the...
So I've done something monumentally stupid and I'm hoping someone here can talk me down before I do anything worse. Been wiring up the solar array on my static caravan — 4 x 200W panels feeding...

Been down a similar rabbit hole recently with my boat setup, so this one caught my attention. Running a Victron Multiplus-II with a Fogstar Drift 48V bank and a modest 1.2kW of panels — nothing as...
@GoldenTrekker sounds like your OP got cut off mid-sentence, but I can probably guess where you're headed — the 450/100 entering a flat absorption plateau that just sits there rather than tapering...
Been looking into something similar for my garden office setup and it's got me thinking about the UK equivalent situation. Has anyone here used a Victron Phoenix Inverter (230V obviously, given...
Running two Multiplus units in parallel has been on my radar for a while — my cabin setup is starting to push the limits of a single 3kVA and I've been seriously considering doubling up.
Had something similar crop up on my boat last winter — Victron MPPT 150/100 just sitting there showing "off" with no obvious reason.
Had this exact issue on my narrowboat last winter. The Multiplus was calling float after maybe 45 minutes when the batteries were nowhere near full — I could see the SOC sitting at around 68% on...
Really solid points all round here. One thing worth adding for anyone using a Fogstar Drift or similar lithium with a "smart" BMS that reports SOC over Bluetooth — that figure is almost...
