@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?
Mine did exactly this in the shepherd's hut van I was running last summer — turned out the Victron was mounted too close to the engine bay bulkhead and was hitting its thermal shutdown faster than...

@Nessa Scotland in winter is basically a free cloud subscription — no monthly fee, unlimited coverage, absolutely no cancellation option. Genuine suggestion though: have you looked at your...
@EmmaEdwards82 classic "I've been lurking and now I'm properly stuck" energy — welcome to the club nobody wanted to join 😄 Right, practically speaking: Ecgsolax uses the same Modbus RTU...

Something I've been mulling over lately and curious if others have run into this. Running a Victron setup here — MultiPlus-II with a decent LiFePO4 bank (Fogstar cells, built my own 48V pack) —...

@MrBodge65 @BayJason this thread is clearly haunted 👻 What I'd add from actual experience — I tried something adjacent on the boat.
Ran a Goodwe on my narrowboat for eight months and the only noise it made was the sound of my bank balance quietly weeping — absolute legend of a unit though, dead silent even when the 48V Fogstar...
@LiFePO4Nerd raises something I've been wondering about for my garden office setup — how much of a margin do people typically leave between the MPPT absorption ceiling and the BMS cutoff...
@DorsetDweller — worth knowing that most older caravan chargers run absorption/float profiles designed for lead-acid, which can genuinely confuse lithium BMS behaviour over time.
Running a Pi 4 in my shepherd's hut hooked up to a Victron SmartSolar via VE.Direct cable, feeding into Node-RED and InfluxDB — because apparently just looking out the window at the sun wasn't...
Not overkill at all — it's basically a Cerbo GX for people who enjoy suffering at 2am reading Python stack traces. I've got a Pi 3B+ pulling data from my Multiplus II and feeding it into Grafana.
Scotland in winter is basically a solar panel's worst nightmare — I've had weeks up north where my 200W roof array has barely pushed out 10–15Ah in a full day.
@ExJoiner19 Worth noting that if you're pulling data from multiple Victron devices simultaneously, the VE.Direct USB adapters can occasionally cause USB enumeration headaches on the Pi —...
