Not my scene — I'm strictly static caravan and tiny house on dry land — but the wiring chaos @BitsAndBobs describes is universal regardless of platform. What I will say: the one thing that saves...

Had the exact same thing last January in my motorhome. The pad was working fine but the sensor placement was the issue — JK reads cell temp not ambient, so if the probe isn't actually touching the...

Seen this on my narrowboat setup — worth checking your absorption time settings in VEConfigure. If the MultiPlus-II is running adaptive absorption, it bases the absorption duration on the previous...

Trying to sort out a bit of a headache on my van build. I've got a Victron SmartSolar 100/20 feeding into a Fogstar Drift 100Ah LiFePO4, which is all working nicely.

@VoltDai the angle thing is massive and often overlooked. If your panels are on a fixed mount, consider that the sun's elevation in December is roughly half what it is in June for most of the UK.

Just to add to what @KangooDream and @VanKev are getting at — the Transit Custom's alternator is almost certainly an Eco Blue smart unit that drops output voltage intentionally to reduce load on...

@ShortCircuit my situation's a bit different — garden office rather than a van — but I went through the exact same internal debate when I was mounting my Fogstar setup. What changed everything for...

Great write-up @VanSue, and welcome to the lithium side! One thing nobody's touched on yet — keep an eye on your low voltage cutoff settings if you've got any 12V appliances with built-in...

@ThistleKen — one thing nobody's mentioned yet: have you verified your clamp meter is actually rated for DC?

Both good points from @LB_Camper and @Robbo51, but I'd add one thing nobody's mentioned yet: check your low voltage disconnect threshold in VictronConnect. On a 12V Multiplus, the inverter will...
@Tango65 three days of cloud in winter? Bold of you to assume it stops at three days in the UK 😅 Running a Honda EU22i alongside my Victron setup here.

Finally got the hut wired up properly last month. Running a 400W Renogy panel into a Victron SmartSolar 100/30 MPPT, with a 200Ah Fogstar Drift LiFePO4 as the battery.

@MarkBennett this is relevant to me too — I run a MultiPlus-II on my boat and had something similar. One thing nobody's flagged yet: check your AC input voltage range in VE.Config.

JasonMoore | 312 posts | — Rule of thumb I use on my boat (similar draw to a small cabin tbh) — work out your daily Wh, divide by your battery voltage, that's your amp-hours needed.

LiFePO4_King | 847 posts | ⚡ Verified Contributor @DazHughes Sounds like it could be a low temperature cutoff situation if you're running LiFePO4 batteries.

Midge55 | 287 posts @PanelPaula Something worth adding to what's been said — LiFePO4 really doesn't like sitting at very low state of charge in cold temps for extended periods.

Good timing on this thread — just went through the same process in my Transit last spring. One thing worth mentioning that I don't see raised yet: check your B2B charger ratings if you're running...

IvyLes | 847 posts Worth adding — placement makes a bigger difference than people think. Had mine tucked against the cab wall in the van and it was working way harder than it needed to.
