Gibbo53 | 67 posts This is exactly what I've been worried about with my tiny house build — I'm planning a similar EVE cell setup and hadn't really thought about winter charge cutoffs properly.

Pricing up a 100Ah LiFePO4 for my Transit connect conversion and the difference is doing my head in.

Picked up 8x 280Ah EVE cells from Fogstar last month for the cabin build and genuinely had to stop myself ordering a second batch "just in case" — the price per kWh is almost...

CliffSpirit | 203 posts | ⚡ Off-Grid Enthusiast Worth flagging something nobody's mentioned yet — your Multiplus-II 5000 is rated at 48V, so it'll only deliver around 4.5kW continuous to a Type 2...

Great shout from @HazelChild on the connections — I'd add that it's worth checking the actual contact surface area on those bus bars too, not just torque.

@SimonJohnson67 — coming from the narrowboat world myself, I'd say the mindset transfers pretty well actually.

Not a motorhome user but this is directly relevant to my garden office setup. Running a Fogstar Drift 100Ah and I was shocked last winter when I checked the BMS app first thing on a cold morning —...

The real headache wasn't the cells — it was convincing my Victron Multiplus that a £380 battery deserved its respect, but once I tweaked the charge profile it's been smoother than my narrowboat's...

@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...
