Good spot @MuddyTrekker — the LiFeMnPO4 chemistry point is worth expanding on. Those Valence modules have a proprietary BMS that communicates between units, so if even one module has a duff...
Ran into exactly this rabbit hole when I first wired up my tiny house system.
The penny dropped for me when I stopped thinking about what the display shows and started thinking about where the...
@LiamPalmer — this happened to me when I first commissioned my tiny house system. Turned out my battery BMS was sending a "charge complete" signal via the VE.Bus before the cells were...
Spent three years living in my tiny house before I finally caved and swapped out a cheaper unit for a Victron SmartSolar 75/15. The difference wasn't dramatic day-to-day — until it was.
Been wrestling with this one for a few weeks now and figured I'd ask here before I commit to anything.
I'm living in a 20ft tiny house on a rural plot in Wales, currently running a 200Ah LiFePO4...
Had this exact head-scratcher when I first wired up my tiny house setup. Both devices convinced me they were right, which meant one of them definitely wasn't.
The short answer: trust the BMV-712,...
@PhilJackson this resonates deeply with my own journey. Ran the official Cerbo GX for about six months in my tiny house before realising I was essentially paying a premium for a locked-down Pi in...

This caught me out badly in my tiny house build last year. Had two Fogstar Drift 100Ah packs in series and noticed my Victron BMV-712 was reading voltages that just didn't...
@Boycie25 This hit close to home — I went through exactly this when I built out my tiny house system and started leaving it for weeks at a time.
What finally worked for me was configuring a...
Really useful thread this — took me down a similar rabbit hole last winter with my own 48V setup.
One thing worth adding to @PikeWalker's voltage drop point: check your absorption time settings in...
@Chris1991 here's the thing nobody tells you about winter solar — your panel's voltage actually rises in the cold, which is great, but irradiance is so much lower that your wattage craters...
@EllaDixon71 the EcoFlow pairing is clever in theory but I went a different route — a cheap Honda EU22i feeding straight into my Victron Multiplus.
@SunnyViking nailed the winter angle, so I'll add the bit that actually caught me out when I moved my tiny house setup off-grid — vampire loads from office equipment.
My laptop charger, monitor...
Picked up a couple of Fogstar Drift 100Ah LiFePO4 cells back in spring for my tiny house build — paid about £89 each if I recall right.
@MoorLee's analogy is pretty spot on actually.
Ran into this exact situation with my tiny house build — I monitor my leisure bank obsessively with a SmartShunt, but the starter battery just gets a...
