Interesting one. The spec sheet looks compelling on paper but I'd want to see real-world data from UK installs before getting excited — we're not exactly blessed with the solar irradiance these...

@OldSailor @DevonDweller both solid points — had this exact nightmare on my motorhome last spring and spent three days convinced my Fogstar battery had gone rogue before realising the VE.Can cable...
QuietTrekker | 1,204 posts | ☀️ Solar Tinkerer Had this exact thing with a Quattro last spring. When it's mid-update and goes unresponsive, don't power cycle it — that's the killer move that...
Had this exact issue last winter with my Multiplus-II 48/3000. Was seeing it drop to float at around 80–85% SOC, which was driving me nuts — especially when I'm trying to get a full charge before...
Been running a Pi 4 (2GB) with VenusOS for about 18 months now and it's transformed how I manage the system.
@KenCross the wall insulation decision genuinely transformed my garden office situation. I went with 100mm PIR board between the studs plus a second layer of 50mm across the face — total overkill...

Had a similar head-scratcher with my Victron setup a while back, so thought I'd share in case it helps anyone else troubleshooting. Running a Multiplus-II 48V with a SmartSolar MPPT 150/35 and a...
Saw the announcement drop for the Victron Multi HS19 Solar 15k — genuinely curious what people here think about it landing in the UK market. From what I can tell it's aimed squarely at that...

@BodgeItAndScarper is right about the Orion, though I'd add — don't cheap out on the cable run to it.
Yeah, had the same faff with mine going into the static caravan setup. Once the engine detection and input thresholds are sorted, the bit that got me next was the charge algorithm — if you've got...

@CotswoldCruiser this is exactly the kind of project I've been eyeing up for my tiny house but haven't had the nerve to start yet.

Great thread this. I've gone a slightly different route — rather than Venus OS I'm running a bare Raspbian install with Node-RED pulling data from my Victron via VE.Direct to USB, then pushing...
@PV_Fan the old "Schrödinger's MPPT" — simultaneously working and not working until Victron decides to observe it properly 😄 Seriously though, had this exact thing on my garden office...
Really good thread this. @CaddyProject makes a solid point about stone behaviour — I'd add that the direction of heat flow matters too.

@GoldenMaker had this exact headache on my static van setup — different inverter but same logic problem. Worth checking whether you've got the grid meter configured correctly in the ESS assistant.

Good thread. One thing nobody's flagged yet for shepherd's hut use specifically — thermal mass is almost zero in those thin-walled timber structures, so your battery will work harder than you'd...

@DevonNomad had this exact drama with my garden office setup — Fogstar battery sitting there half-charged while the Victron smugly declared "job done" like it had just completed a...
@QMC_Camper @CrafterConvert — yes, been there! What caught me out beyond the engine detection was the input voltage lockout settings.

Has anyone actually tested the charging efficiency difference on a boat install? I'm wondering whether the losses from PWM vs MPPT are more pronounced when you've got longer cable runs to contend...

@BorderWanderer absolutely the right approach in my view. The SmartShunt's coulomb counting is simply more accurate for day-to-day SOC tracking than BMS voltage-based estimation, particularly at...
