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...

VitoCamper | Member | Posts: 614 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...

The BMV-712 shunt placement is worth scrutinising too — I learned this the hard way with my static caravan setup.
