The thing that swung it for me was realising my Victron kit—the multiplus, the MPPT—was doing more heat shedding than the batteries themselves.

The heating element's absolutely the bottleneck here. I learned this the hard way retrofitting my van conversion — ran the numbers expecting it'd work with my 10kWh LiFePO₄ bank, but a single wash...

Spot on, though I'd say the paralysis trap hits differently depending on your setup type. With my static caravan, I made the mistake of designing the "perfect" system before installing...

Portable panels are decent for testing the waters, but honestly if the landlord's genuinely onboard, fixed installation makes more sense long-term.

The usable capacity chat is dead right, but I'd also push back slightly on treating DoD as this fixed rule.

@DodgyRoamer's nailed it. The psychological bit sneaks up on you. I went full paranoia mode my first winter—obsessively checking battery state of charge, running the genset at 2am because I'd...

Spot on about the tracking period. I'd also factor in your usable capacity — most folk forget that LiFePO4 systems shouldn't drop below 20% to avoid premature degradation, and lead-acid is...

Has anyone retrofitted a proper split charge system into an older campervan? I'm looking at picking up a fairly basic van and wondered if it's worth upgrading the leisure battery setup from the...

Spot on choice finding this place. I was in exactly your position two years back when I was spec'ing out my van conversion setup — got lost in endless Reddit threads and YouTube rabbit holes...

The 100Ah is workable for weekends, but continuous cruising's a different beast. I'd be targeting minimum 200-300Ah for genuine liveaboard peace of mind. Key difference from stationary: your...

Worth asking what battery chemistry you've gone with @CotswoldNomad — that'll dictate your DoD strategy pretty heavily.

Thermal management's the real killer with Sprinters—@CarlBaker's spot on. I've seen folks lose 15-20% efficiency just from panels running hot in summer.

@ExFarmer's proximity thinking is understandable but @VivaroWanderer's spot on — I learned this the hard way with mine.

Spot on about the lock gate tax, @ForestDaz. I've been mulling this over for my shepherd's hut build and even that's got spatial constraints, though nothing like a narrowboat's nightmare. The real...

Caravan solar's a good shout — you'll get proper answers here without the usual nonsense. The community knows what actually works in the UK climate, not just theory. Fair warning though: once you...

The heating cycle is brutal, yeah, but @DodgyMechanic's got the right idea about timing. On my narrowboat I solved this differently though—switched to a 12V portable wash unit (basically a...

Grabbed a bundle of knackered-looking 250W Canadas myself for the static caravan last year — seller swore blind they were "just dusty" and he wasn't wrong.

Cheers for the detailed replies, @FormerMechanic14 and @Boycie. Just to add from my own boat experience — I went through this exact dilemma last year and ended up measuring my actual cable run...

The inrush thing is absolutely crucial — you lot have nailed it. I've got a Fogstar fridge in my narrowboat and learned this the hard way.

State of Charge, innit — basically your battery's fuel gauge but actually matters because lithium especially throws a tantrum if you drain it flat or keep it perpetually topped up.
