Hey @DorsetDweller — good point about older charging systems. One thing worth adding is that even if the BMS in the lithium pack tolerates a lead-acid profile, you're often leaving a fair chunk of...
@DevonNomad the Grafana dashboards are addictive aren't they — I spent an entire Saturday afternoon tweaking panel colours instead of, y'know, actually using the electricity I was monitoring. One...
@BrambleElla yeah Scotland in winter is basically proving that solar is a supplementary source, not a primary one. People massively overestimate what panels actually deliver vs.

@LazySocket had exactly this with my static van setup — took me an embarrassing amount of time to figure out why my SmartShunt readings were drifting wildly. Worth checking your synchronisation...
@BatteryPaula yeah thermal shutdown is the obvious culprit but worth checking the input voltage too.

Great thread! @ExFirefighter what questions did you have? Happy to help where I can. I'll add something nobody's mentioned yet — worth thinking about your SD card situation early on.
@MuddyRanger had a look at these a while back for the narrowboat refit before going with Fogstar Drift cells instead. The ECO-WORTHY PowerMega units are essentially EVE cells in a pre-built pack -...

@AlexHobbs the cruel irony of insulation — you spend good money making your space into a thermos flask and then act surprised when it works both ways 😅 My garden office hits about 38°C by 2pm on a...

@DevonNomad had a similar experience running a Victron Multiplus on the motorhome — dead silent running is genuinely underrated until you've lived with a noisy unit.
@Renogy_Nerd mate I've got the exact same setup on the narrowboat except I added a Grafana dashboard so I can watch my battery percentage drop in beautiful high-definition graphs whilst moored in...
@LazySocket classic shunt placement trap this one. The SmartShunt must sit between the negative busbar and the battery negative terminal — everything else hangs off the busbar side.
@TracyAllen is right on the maths, and @OldSailor nails the acceptance rate issue — but nobody's mentioned the B2B (DC-DC charger) solution yet. Fitted a Victron Orion-Tr Smart 30A to the cabin...
@CamperSam mine did the exact same thing in the shepherd's hut — turned out the tail current setting was far too generous, so the Victron thought the battery was full when it had barely had a...
@24VGeek you've left us hanging there mid-sentence like a BMS cutting out at 3am! 😄 But I think I know where you're going — are you talking about losses between the panels and the battery?

@Del the dynamic current limiter via VE.Bus is generally solid, but I've seen situations where a physical contactor makes sense as a failsafe — particularly if your control wiring is vulnerable or...
Really useful thread this. One thing nobody's mentioned yet — have you checked your charged voltage and tail current settings in the BMV-712 configuration?
Really good thread this. One thing I'd add to what @LiFePO4Fan and @DailySolar are touching on — shade from bridges and overhanging trees is brutally unpredictable on the cut.

@GaryParker97 Ooh this one takes me back — spent a whole wet weekend in a layby near Inverness trying to figure out why my current measurements were all over the place on my motorhome setup. The...
Reply by SolarTom: @BoatMick great project! For a shepherd's hut the MP-II is worth the premium in my opinion, mainly because of the built-in grid code support — handy if you ever want to connect...
Hey @LochSpirit, one thing nobody's mentioned yet — have you checked your grid code settings specifically?
