TransitNomad | Posts: 847 | Location: Canal network, somewhere near Middlewich @OffGridTel for a narrowboat I'd honestly push you toward 48V without much hesitation.

Moored up on the Shrewsbury canal last January, minus four overnight, and I woke to a completely dead boat. No inverter, no heating fan, nothing.

LDVConvert | 412 posts | Array The panel-to-battery ratio is worth scrutinising here. 400W feeding a 200Ah bank is actually reasonable sizing, but your real constraint is the 100/30 MPPT — that's...

EwanGreen | 847 posts | Orkney @HighlandExplorer that storm was brutal wasn't it — felt it down here on the islands too. My rule of thumb for a Scottish winter three-dayer: I won't feel...
KangooWanderer | 1,203 posts | 🚐 Converted Kangoo + Narrowboat @ForestDweller I'm literally in your exact situation — Kangoo camper and a 57ft narrowboat, both running LiFePO4.

I've had a Victron Orion-Tr Smart 12/12-30 running between my van starter battery and a 100Ah lithium leisure battery for about six months now.

Hey @JackieScott, something nobody's mentioned yet — have you checked whether there's any shading creeping in during winter that wasn't an issue in summer?
FZ_Builds | 312 posts @PU_Sparks The JK BMS SoC readout is honestly decorative at best — treat it as a rough guide rather than gospel.

BurnWalker | 89 posts Running a single 30A on my narrowboat and honestly questioning whether I should've gone parallel from the off.

Updated mine to the latest firmware last night (v4.12) and now the state of charge is all over the place.

Slapped a small turbine next to my panels last autumn and honestly the thing earns its keep on every miserable grey day that would've left my Fogstar batteries looking sorry for themselves —...

@KevLee nice one — I went down a similar rabbit hole last year with a Renault Zoe pack. Ended up with six modules running in my old Hymer, giving me around 14kWh usable after I'd set conservative...

Kate1970 | Posts: 847 | Location: North Yorkshire @SolarGeorge worth checking your PowerAssist settings in VEConfigure — if it's not set up correctly it won't properly supplement the inverter...

@GrumpyHermit replied: Worth it? Yes, but only if your expectations are realistic. A 100W panel through PWM will genuinely disappoint you on a grey November morning — and let's be honest, this is...

Good thread this. @GoldenMaker one thing worth considering alongside what @CumbrianOffGrid is hinting at — have you logged your Leaf's battery degradation since starting this?

EcoFlow_Queen | 847 posts @Mike1997 the key thing nobody's mentioned yet — both MPPTs need identical absorption and float voltage settings, not just similar ones.

@QMC_Camper the critical figure here isn't wattage — it's whether the Isc values are reasonably matched.
