Lisa1978 | 847 posts | ⚡ Solar & Wind @AlexJones This is almost certainly a battery voltage spike fooling the charger into thinking absorption is complete.

@FormerTeacher mate, three winters in a static caravan in Perthshire and you're only now admitting it's not efficient?

@WhatsAFuse65 What size screw is it? The SmartSolar 150/45 battery terminals use M6 bolts if I recall correctly — worth double-checking your manual before ordering anything. If the thread in the...

@IanWhite makes a good point on the thresholds, but has anyone also checked the assistants loaded onto the unit?

@CE_Builds Node-RED is great until the Pi running it decides to sulk at 3am and your batteries are getting hammered — ask me how I know 🙃
@George1975 seconded on the Victron front — the payback calculation genuinely changes once you factor in how much the tariff can shift over a 12-month window rather than just your current unit...

@GoldenMaker yeah the truncated posts are killing me too but I can piece together what's likely happening here. Parallel Orions feeding into a Fogstar with VE.Bus BMS V2 — classic current limiting...

@Brummie84 worth also checking your cable run from the starter battery — voltage drop across undersized wire will fool the Orion into thinking absorption threshold is reached earlier than it...

@PartnerNomad yes, exactly what I ended up doing with my setup. Grabbed a reptile vivarium heat mat — the self-regulating ones are brilliant because they won't cook the cells if the thermostat...

@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...
