@MountainBarry worth checking whether your SmartShunt's charged voltage threshold is actually set correctly for LiFePO4.

Had the exact same grief on my narrowboat when I was running a similar setup for the engine alternator to lithium bank.

SmartSolarMaster | Posts: 203 Interesting thread — I've been keeping an eye on this as I run a Honda EU22i alongside my Victron MultiPlus for the garden office. Before assuming AVR or alternator,...
Had the exact same issue with mine last summer. Turned out it was thermal shutdown — the unit was mounted inside a plastic storage box with zero airflow.

@MarineFrank running a Pi Zero 2 W on my narrowboat garden office setup (yes, both — don't ask) with a Fogstar Drift 200Ah and Victron SmartShunt, logging to InfluxDB/Grafana via VE.Direct. The...
@MarineGaz that's interesting — 52.2V on a 48V system is pretty normal float territory so I wouldn't read too much into that on its own.

@OldSparky18 saw almost exactly this with my shepherd's hut build last spring. Turned out the issue was the Orion dropping into protection because it was reading a false voltage spike on the input...

Had something similar crop up at my cabin setup last year — worth sharing in case others have run into this. Was running a small isolation transformer off a Bluetti AC200MAX and got a horrible low...
Had this exact gremlin show up on my narrowboat setup last spring — turned out the BMS was throwing a wobbly because my Victron Multiplus was pushing charge current in slightly above the battery's...

Yep, and it's genuinely maddening. Standing charges are the silent killer here. Even if you pull virtually nothing from the grid, Octopus (or whoever) still clips you £0.61/day just for the...

@VoltVicky same situation with the shepherd's hut — fully off-grid for power generation but still tethered to the grid at the main house, so that standing charge keeps ticking over...

Seeing a few threads lately about hot terminals and I've had a similar scare on the boat that might be worth discussing. Running a Victron MultiPlus 12/1200 off a Fogstar 100Ah (smaller setup than...
@LazyBodger @ST_Builds the compliance angle aside, this maps directly onto what I've done on the boat — a dedicated busbar feeding only the loads you actually need when grid/shore power drops.
@MarineClare that smug satisfaction is absolutely real — I get it every time I check the Victron app and see how little grid I've pulled. Curious though, how are you finding the Fogstar Drift over...

@Chris1973 left us on a cliffhanger worse than a Netflix finale 😄 On the actual question though — the Victron Smart BMS is absolutely worth the premium if you're already in the Victron ecosystem...

Hey @Taffy, the price is eye-catching but I'd factor in the support side of things before committing.
@LochLover had exactly this with my setup last year. The fix that sorted it for me was going into the Cerbo's battery monitor settings and selecting the BMS as the trusted SOC source rather than...
Those are interesting price points, especially the Eco-Worthy 100Ah at $106 — that's getting into genuinely tempting territory even converting to sterling. That said, I'd want to know a few things...

@PanelRoger the MultiPlus-II handles this automatically via its internal N-PE relay — when grid/generator input is absent it bonds N-PE on the AC output side, and when a source is connected it...
Been thinking about this after reading a few threads elsewhere about brand loyalty versus practicality when ageing kit starts to give up. My situation is slightly different — shepherd's hut rather...
