@NeilJackson had almost exactly this with my Camper Van build last spring. The Multiplus was doing that thing where it refuses to accept shore power because the site hookup is slightly outside its...

@GlenDixon had this exact drama on my narrowboat two winters back — panels in series, crisp November morning, controller sat there doing absolutely nothing while my batteries quietly sulked. What...
@GlenChild been there — woke up in my motorhome convinced I'd finally achieved true off-grid enlightenment, turns out I'd just achieved true off-grid darkness because the JK had gone full drama...

ShedGenius | 1,203 posts Worth checking the BMS firmware version first — JK pushed an update a while back specifically addressing BT stability during high-current events.

RockyMaker | 312 posts Great thread @ExChippie30! The key thing nobody's mentioned yet is timing your charging session to coincide with peak solar production rather than just plugging in whenever.

Had both in my static setup at different points. The Victron wins on ecosystem integration — if you're already in the Victron world with a MPPT or Cerbo, the Bluetooth monitoring and VE.Smart...

Turbo19 | Posts: 312 @Mark1978 One angle worth considering - if you're on Octopus Agile or similar time-of-use tariff, the Multiplus II plays very nicely with Node-RED or Victron's own ESS...

@Jess1972 The physical size threw me off too when I first installed mine in a Sprinter. Worth remembering that a decent chunk of that bulk is the thermal management — Victron's built the...

@PanelDai one thing I'd add that nobody's mentioned yet — have a look at whether your Giandel draws a consistent enough idle current that you can use the SmartShunt data to infer inverter state...

@HighlandNomad had almost identical with my garden office setup. Turned out my absorption time was set too short in VEConfig — it was hitting voltage target fast under low load and just rolling...

@VanKev worth knowing that the Victron MultiPlus 12/3000 will struggle to sustain meaningful house loads for long — you're limited by the 12V battery bank capacity more than the inverter rating.

ChloeScott76 | 134 posts @ExChippie30 Great thread! I charge a Nissan Leaf from my off-grid setup occasionally and the key for me has been using a timer to drip-charge during peak solar hours...

Great thread! I've got a 200Ah Drift on my 57-footer and it's been brilliant. One thing I'd flag specific to narrowboat life that hasn't been mentioned — keep an eye on your alternator charging...

EwanLamb | Posts: 847 @MountainBarry before you do anything else, I'd recommend letting all the cells rest at room temperature for 24-48 hours if they've just arrived — especially coming into...

BenWebb | Posts: 312 @Mark1978 Good timing on this question - I made almost the same switch last year with a similar setup.

@VanHolly great setup — I ran something similar on a 60ft trad stern for a couple of years. One thing worth mentioning that I don't see covered above: think carefully about your battery state when...

@RustyRoamer been running a SmartSolar 100/30 on the narrowboat for two years now and the VictronConnect integration is genuinely the deciding factor for me.

Right so this exact thing had me scratching my head with my static caravan setup — different context obviously but same principle. What sorted it for me was understanding that the Orion...
