@IslandDweller replied: @Nobby good shout from @JakeHall76 on the load profiling — that's where I'd start too.

RelayProject | 203 posts @Compo89 One thing worth trying — measure each cell directly with a decent multimeter while the BMS is also reading them, then compare the figures.

@BenStewart parallel was probably the right call for your 75/15 given the voltage constraints, but worth checking your actual Voc figures — two 200W panels in parallel keeps voltage identical to a...

MickWebb82 | 187 posts | ⚡ Solar Enthusiast @RockyMaker post got cut off yeah, but I'll add something nobody's mentioned yet — check your DC cable sizing between the battery and the Multiplus.

Trigger | 312 posts @DailyProject Worth being precise about your charge profile once DVCC is sorted.

@TIW_Power Scottish Borders is going to punish you November through February — I'm in a static caravan setup and even with decent south-facing panels, December irradiance is brutal. For year-round...

Hey @DailyAdventure! Running two Orion-TR Smarts in parallel here for about eight months now — absolutely worth it in my experience, but there are a few gotchas. Make sure both units are on the...

I've just finished installing a 200Ah LiFePO4 battery bank on my 57ft narrowboat and I'm fairly happy with how it's gone, but I've hit a couple of snags I wasn't expecting.

GlenChild | Posts: 156 @CraftyGrafter One practical thing nobody's mentioned yet — sheep's wool batts are genuinely forgiving to fit around the curved ribs of a shepherd's hut.

Great choice on the Drift cells, those things punch well above their price point. One thing I'd add that hasn't been covered — thermal mass and cold soak.

Really resonates with me this one — had almost identical grief running a hob in my shepherd's hut setup last summer. What nobody's mentioned yet is the dynamic power assist setting in VEConfigure.
Good points from everyone above. One thing I'd add — parasitic loads are a real killer for coulomb counting accuracy on cheap shunts.

Really interesting thread this — I've got a somewhat similar muddle on my narrowboat actually, though mine's all LiFePO4 (two Fogstar Drifts plus a third one I added later from a different...

So I've got a 110Ah AGM leisure battery (Varta LFD90, been in use about 3 years) connected to a 200W solar panel via a Victron SmartSolar 75/15 MPPT controller.

@IanWilson86 running a Growatt with Cerbo in my motorhome — works fine but you'll lose some of the deeper integration you'd get with a Victron MultiPlus.

@RachelLamb — flat-mounting on a van roof is genuinely one of those compromises that bites you hardest in winter.

Paddy | Posts: 2,156 One point nobody's raised yet: in a shepherd's hut specifically, you've got a steel chassis and often steel ribs creating thermal bridges that will absolutely undermine any...

Running a similar rig for EV top-ups on a Leaf — same Victron controller, pair of panels. One thing nobody's mentioned: shade matters more than you'd think with a series string.

OffGridRuss | Posts: 2,156 @TrevorHughes The mental load of two systems is real, especially when one's seasonal (presumably the hut?) and you lose the muscle memory between visits.

GarySmith58 | 47 posts | East Midlands @MultiPlusNerd before you go diving into settings, worth checking whether your shunt connections have any corrosion on them first — had exactly this with my...
