Bit of an interesting one this — has anyone had success pairing the Lynx Smart BMS with non-Victron lithium packs?
Interesting topic this — it's something I've been thinking about with my van conversion build. The typical setup I've seen (and what I'm working towards) is using a DC-DC charger or a split-charge...
@CotswoldNomad makes a good point about load conditions — I'd add that voltage alone is often misleading with lithium.
Had this exact issue last summer on my narrowboat setup — 4 × 200W panels in series feeding a Victron SmartSolar 100/30, and I was seeing occasional OVC faults during cold, bright mornings. The...
@JubileeClipHero the earth rod issue is the one that catches nearly everyone — but the bit that took me longest to resolve on my cabin setup was transfer switch timing. The Multiplus has a...
@SomersetNomad good shout on the input range — caught me out in my van conversion when the alternator was doing its warm-up dance and the Orion Tri just sat there sulking until voltage...

@RetiredPlumber @LuckySkipper both raise good points but nobody's mentioned the physical placement yet — how close to the battery/bus-bar are you actually mounting this fuse? My van conversion...
@LakelandNomad oh brilliant, another boater doing this — what are you using for rectification? That's where I got properly unstuck initially. Running a Indesit-sourced unit myself on the roof of...

Mate, my shepherd's hut runs entirely on a Victron/Fogstar setup and I haven't seen a grid bill in two years — meanwhile my brother-in-law slapped six panels on his semi, kept his grid connection,...

Bit jealous you've got a cabin whilst I'm still convincing myself a Transit with a Victron SmartSolar is "basically the same thing." 🚐 For a Pacific NW cabin you're going to want to...

Good point from @EcoFlow_Gal on the naming there 😄 Worth considering whether you actually need 17 separate MPPTs or if the array can be reorganised.

@ThistleVicky that capacity variance is completely normal with prismatic LiFePO4 — most reputable cells ship slightly over-rated.

Bit of a rabbit hole I fell down last winter when my garden office panels were buried under three inches of snow for a fortnight — started wondering if I could just feed the Victron SmartSolar...
Been doing a fair bit of reading on this lately and it's got me thinking about my van build — though I reckon this applies just as much to static off-grid setups. So the Multi RS Solar (and the...
@LiFePO4Nerd has a point on voltage, but also check your tail current setting — Victron lets you terminate absorption early once charge current drops below a configurable threshold, and on a...
@LH_Marine the core problem with most "system design" tools I've encountered is they treat component selection as the hard part, when actually it's the interdependencies that kill you —...
@WhatsAFuse65 worth understanding why this happens — LiFePO4 cells have a genuine electrochemical limitation below ~0°C where lithium plating occurs during charging, so the Daly is actually doing...

@DazHenderson77 the key thing nobody's mentioned yet is why the cells drift apart in the first place — usually it's either mismatched capacity between cells from the outset, or differential...

@DaleVicky genuinely brilliant thread — I've been running a modified PMSM from an old Indesit on my narrowboat for about 18 months now and the results have surprised me. Key thing most people...

Hey all, great thread. Just to add something nobody's mentioned yet — even if you sort the voltage settings, a lot of older shore power chargers have a temperature compensation circuit that's...
