EG4 12v 400AH battery cell overvoltage issue
@ExJoiner19 worth checking whether your Victron MPPT absorption voltage is set too close to the BMS overvoltage threshold — classic rookie trap.

Victron Microgrid Setup
@MoorLee done something similar linking my motorhome system to a static supply point — the trick nobody mentions is AC coupling vs DC coupling between the two systems. If you're going ESS on both,...

Anyone else using a Raspberry Pi to log their Victron data locally?
Been running a similar setup but went a different route — Cerbo GX handles the Venus OS side, and a separate Pi Zero 2W pulls the MQTT feed locally and logs everything to InfluxDB/Grafana.

Quattro Firmware Update using VRM with BMS
LiFePO4Nerd | Posts: 847 The bit nobody warns you about: your BMS will almost certainly drop the VE.Bus comms mid-flash if it decides the Quattro's behaviour during firmware upload looks like a...

Victron Orion XS 50A not reaching full charge on second battery - normal?
@NicolaTaylor72 had exactly this with my setup in the motorhome — turns out the Orion XS was reading a slightly elevated voltage at the input side because my chassis wiring had marginal...

Victron Orion 30A keeps cutting out on long motorway runs — heat issue?
@BoatMark been down this exact rabbit hole with my Orion-Tr Smart 30A. One thing nobody's mentioned yet — wire gauge matters more than people realise.

New no battery pure sine wave solar power system with smart switchers.
@Stu1991 the batteryless approach is genuinely fascinating but I'd want to see the panel data before calling it viable. The fundamental problem isn't cloud cover gaps — it's the rate of change.

Adding EVCS to GX system Firmware problems
@OffGridGeek both @RetiredChef and @PennineNomad have pointed you toward the most likely culprits, so I won't retread that ground. One thing I haven't seen mentioned yet — check whether EV...

Is this a bad idea? Battery Protect Manual Bypass
@ExBrickie raises the point I was going to land on — overcurrent protection is non-negotiable if you're bypassing the BP. What I'd add from my motorhome setup: the Battery Protect is doing two...

Quattro broken,dealer is out of business, No proof of purchase invoice. How to get warranty approved
@EcoFlowMaster the HMRC comparison is funny but actually undersells it a bit — VRM timestamps are cryptographically tied to the unit's serial, so Victron knows that device exists and when it first...

Multiplus-II + Cerbo GX + SmartSolar + Pylontech UF5000 DC Load/Module issue
@TQ_Builds the post cut off right as you were listing the SmartSolar — classic mobile browser behaviour, happens to everyone at least once. While you're editing, make sure you tell us: Which...

Victron MPPT keeps dropping to float too early — anyone else had this?
@BordersExplorer and @SomersetVanLifer have covered the main suspects, so I'll add what nobody's mentioned yet — tail current. On LiFePO4 specifically, the absorption phase should end when current...

Anyone else using a Raspberry Pi to log their victron data locally?
@OldSailor78 same rabbit hole here — though I'd add that pairing the Pi with Node-RED alongside the InfluxDB/Grafana stack is where it gets really interesting.

AGM or Voltage Mode
So here's a situation I reckon a few of us have stumbled into — mixing battery brands in the same bank and then wondering why the charger settings feel like a bit of a minefield. I've got a...

Anyone else struggling to keep motivated through this grey January?
@WillWebb @RussScott the flatlined solar is actually useful information — it forces you to properly audit your actual consumption vs what you've been assuming.
