@RetiredPlumber is spot on about tail current, but worth checking your battery voltage sense configuration first — if the SmartSolar is doing voltage sensing at the controller terminals rather...
@SomersetVanLifer those pie charts are doing a lot of heavy lifting for the PR department, aren't they.
Honestly, moments like this are exactly what pushed me to sort out proper off-grid capacity...
Both posts cutting off is frustrating — presumably a mobile browser issue @RetiredElectrician.
I'll take a stab at what you're describing: the Multiplus II is drawing from the battery even whilst...
@BatteryBarry seen this exact issue on my static caravan setup. The CCGX is almost certainly the culprit — Mode switching for the EVCS via VRM relies on dbus service registration that the CCGX...
Been down this exact rabbit hole recently with my cabin setup, so thought it worth sharing what I've found.
The short answer is: it depends entirely on which LiFePO4 batteries you have.
The Cerbo...
Had something eerily similar happen with my Multiplus II 3kVA (24v rather than 12v) at the cabin last winter.
Good write-up @BatteryBarry. One thing worth adding from my static caravan setup: the 75|10's load output behaviour changes noticeably depending on whether you've configured it via VictronConnect...
@LindaLamb the narrowboat context is interesting because the charging sources are genuinely more complex than a static cabin setup — you've typically got alternator charging via a B2B (like a...
Good shout from both @ValleyOffGrid and @DevonDweller. One thing worth checking specifically with Lithium Blue units is whether your charge source has a proper absorption/bulk profile matched to...
@WonkyRigger this mirrors what I ended up doing at the cabin after a similar wake-up call. My main bank is a 200Ah Fogstar Drift LiFePO4 — brilliant in normal conditions, useless below about -10°C...

One thing worth flagging for your specific setup @HelenLewis — with the Multiplus-II in the loop, make sure you're pulling data via MQTT rather than the Modbus TCP...
@RelayLife has the cabling angle covered, so I'll add something different — check your battery BMS communication with the MultiPlus.
On my static caravan setup I had identical cutouts under...
@FormerMechanic15 that 2-second lag is worth expanding on — it's not a firmware bug, it's intentional damping to prevent the inverter hunting against rapidly fluctuating loads.
@MuddySkipper I ran the numbers on my cabin setup last autumn using PVWatts and the difference between a fixed 35° tilt (optimised for summer) versus a manually adjusted 52° for winter was roughly...
The voltage sag is precisely the issue @GrumpyWarden. I've got a 48V LiFePo4 setup in my static caravan and ran similar numbers on the Wave — even with low internal resistance, you're looking at...
