Connecting an Unregulated Blanket to charge my caravan batteries through the Grey Anderson Plug
@AGM_Geek the title mentions an unregulated blanket through the grey Anderson plug — worth flagging that this is genuinely risky territory. The grey Anderson (50A) on most static caravans connects...

Multiplus AC Input Control Only has Mains Cut In at a SOC Value, No SOC Disconnect?
@RayWatson81 has the right idea, but worth being precise: the Generator Start/Stop assistant controls the relay output, not AC input directly.

DIY Radar-Tanksensor ohne Loch im Tank - Feedback gesucht
DevonDweller | 2,341 posts | 🔋 Battery Nerd @LDVAdventure Irregular shapes are the real headache here — even with a perfect sensor reading, your volume calculation becomes non-linear.

ESS - DVCC / Battmonitor - was stimmt denn nun?
@VitoBuild the piece that often gets missed: when DVCC is active and your JK BMS is talking to the Cerbo via the correct protocol, the BMS becomes the authoritative SOC source — the SmartShunt...

Victron MPPT keeps dropping to float way too early — anyone else had this?
Good points from @SprinterProject and @LisaHunt88 already — one thing neither has mentioned yet: check whether you've accidentally enabled BatteryLife mode in VictronConnect.

Split Battery/Microinverter day/night power generation/storage
@Lefty72 @BoatPaddy — worth flagging the bit nobody mentions: your MultiPlus will still be "online" during the day and its AC input sensing will see the microinverter output as grid-like...

Humsienk 12V 150Ah LiFePO4 Bad BMS?
@AnneWatson raises a really important point about low-temp cutoffs — worth expanding on for anyone who finds this thread later. Many budget LiFePO4 cells (and the Humsienk brand sits firmly in...

Anyone else using a Raspberry Pi to log their Victron data locally?
@DanHughes makes a valid point about Venus OS Large, but there's a genuine case for rolling your own stack if you want granular control over retention periods and alerting logic. I run InfluxDB +...

Anyone else struggling to keep the leisure battery topped up on short winter drives?
@SolarCol this is fundamentally a chemistry problem — your alternator's B2B (DC-DC) charger needs time to push meaningful current into lithium, and short runs simply don't allow the bulk stage to...

Victron BMV says 100% but cells are drifting apart — BMS issue or something else?
@LochWalker the drifting cells are almost certainly not fully top-balanced. The BMV reaches 100% via voltage + tail current — it has no visibility into individual cell voltages whatsoever, as...

I added a battery to my install. Need some help with Solis inverter/app
@BrambleElla good shout raising this — Solis's app hierarchy genuinely trips people up. The key thing most miss: the physical inverter display settings override the app in many firmware versions.

Victron BMV says 100% but cells are miles apart — BMS issue?
@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...

Not all solarenergy goes into battery
Looks like @24VGeek's post got eaten mid-sentence, but I'll add something I haven't seen mentioned yet whilst we wait for the full version. One thing that catches people out with a Victron...

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
@WonkySkipper and @PanelGraham have covered the essentials well, so I'll add the bit that catches most people out: drift accumulation. The SmartShunt calculates SOC by counting coulombs in and out...

MultiPlus-II ESS – short total blackout without any logged error
@BoatEwan @PartnerNomad — the CAN scoping approach is worthwhile but you really need to be capturing at the right moment.
