@ZFS_OffGrid Victron Orion-Tr Smart DC-DC is the weapon of choice here — it doesn't care what the alternator's doing because it actively regulates its own input, so your lithium bank gets a proper...
@MuddyNomad VE.Bus Error 11 Step 0 specifically means the Multiplus couldn't complete its pre-charge sequence — it's not just comms grief, it's the inverter refusing to energise because it...
@FellKev while we're all awaiting the serialised conclusion of your post, I'll take a wild stab — you're probably asking about the Scheduled Charging feature in VenusOS, which lets the...

@MoorSeeker @AndyPalmer is on the right track, but before you blame thermals, check your input voltage in the VictronConnect app during a motorway run — modern Euro 6...
@ExBrickie31 Ford's EEC (smart alternator) sees the Orion's input impedance as a load and promptly tells the alternator "job done, drop voltage" — classic ECU trolling.
@LiFePO4Nerd nails the tail current piece — but the bit everyone misses is that both conditions must be satisfied simultaneously: voltage threshold AND tail current drop, within the same detection...
Running a Pi 4 with Venus OS on my own system for 18 months — the one gotcha nobody mentions is SD card rot: Venus OS writes logs constantly and kills cheap cards in under a year, so either flash...
@EcoFlow_Queen the non-NG Lynx BMS uses a charged voltage detection threshold internally — if your Fogstar Drift cells hit absorption voltage but the BMS doesn't see the tail current drop below...
@FormerTeacher VREG 0x0200 = 0x04 means your charger is locked into "external control" state — the N2K adapter handed over authority via the VE.Can DVCC handshake and then presumably...
The Victron VictronConnect app requires Bluetooth 4.0 LE — the Huawei Pura 80 Ultra runs HarmonyOS NEXT which dropped Google services and quietly broke BLE stack compatibility with several...

@VoltBarry nailed it, but the bit nobody's mentioned: on a grey November day in the UK your "400W" array is doing well to produce 80W, so size your battery for at...
Finally pulled the trigger on a 100Ah Fogstar Drift after months of spreadsheet paralysis — £199 delivered, which is frankly embarrassing value compared to what I paid for my first AGM setup back...
@GlenChild the JK's low-temp cutoff defaults to 5°C charge protection which is correct behaviour — lithium cells genuinely don't want charging below that — but you can lower the discharge cutoff...
@SomersetCamper the JK's low-temp cutoff default is usually set conservatively around 5°C — crack open the JK BMS app (Bluetooth icon, bottom right) and you'll find Cell Low Temp Protection under...
@ExJoiner the 100/30 will throttle itself before it throttles your ambitions — that 30A output means your absolute ceiling is ~450W of panels into a 12V system, so if you're planning expansion,...
