OakTom | Posts: 1,203 @KangooBuild Worth flagging that on a 48V system the 100/50 also limits your array voltage to 100V Voc — that's pretty restrictive once you start stringing panels in series...

@CopperRoamer genuinely good point — I nearly skipped proper fusing on my tiny house build and I'd have regretted it. Quick question for the thread though: does anyone have a rough breakdown of...

LindaClark90 | 203 posts Oh this is exactly my situation! Narrowboat with a Fogstar/Victron setup plus a separate bank in my garden office on the towpath — so technically both on land and water...

Seconding what @Geordie said about VictronConnect — the history graphs are gold for diagnosing this. One thing nobody's mentioned: check your AC output wiring too, not just DC side.

DaleSeeker | 412 posts | 🔧 Tinkering Since Forever Worth checking whether your JK is set to cut on discharge or charge at low temps — they're separate parameters and it catches people out.

Great thread, this catches a lot of people out. One thing nobody's mentioned yet — have you checked the AC input current limit in VEConfigure?

FormerMechanic14 | Posts: 1,203 @OakTel JK BMS units ship with the low-cell cutoff set at 2.5V from factory – that's your problem right there.

Mine dropped connection so many times I started wondering if Victron was ghosting me on purpose — turns out I had two phones both paired to it simultaneously, which apparently sends the Bluetooth...

@HalfAJob — the narrowboat life, eh? Nothing like a dodgy SOC reading at 11pm on a rural cut to really sharpen your troubleshooting instincts. Something nobody's touched on yet: temperature...

I've got a Renault Trafic SWB I'm in the middle of converting and I've just fitted a 240Ah lithium (LiFePO4) bank made up of two 120Ah Fogstar Drift batteries wired in parallel.

Chiming in here as I've got a very similar setup in my campervan — Multiplus-II paired with Pytes E-Box 48100R.

Been messing about trying to get a cheap EV charging setup running off solar on my boat — not a full home install, just something sensible for topping up a small EV when moored up.

SarahFrost | 312 posts @JakeHall76 Great combination — I run almost exactly the same setup in my cabin in the Scottish Borders!

Ran a Multiplus 12/3000/120 in my van for three years before moving it into the garden office, so I know that transfer switching well. One thing worth knowing on marina hookups specifically —...

PanelChris | 847 posts @LindaPrice87 depends entirely on your loads, really. 400W solar + 100Ah LiFePO4 is a decent starting point but could be tight in winter.

The split charge relay with LiFePO4 is basically asking your alternator to die heroically so your battery can live — the Orion-Tr Smart's current limiting alone is worth the price of admission on...

My narrowboat setup laughs at your panels getting 11 minutes of usable sun in January — though to be fair, 200Ah of Fogstar is doing the heavy lifting when the sky goes full grey flannel for a...

@DownsDweller one thing worth checking before you spend money on more batteries — have you looked at your actual consumption patterns with Victron's VRM portal?

SamStevens60 | 📍 Cambridge Fens @FenlandOffGrid Worth mentioning that on genuinely clear winter days you'll often see a decent spike around solar noon — don't be discouraged by the averages.
