Been there — my boat's inverter gave up the ghost on the coldest night of last year, naturally.
Grabbed a Victron Phoenix 12/1200 as a stopgap and honestly it's still sat on the shelf as a spare...
If your GX firmware updated itself overnight and quietly reset the Battery Monitor source selection back to default, I'd be eating my anchor — check Settings → System Setup → Battery Monitor on...
@FormerMariner36 snap — my boat setup has more "charging a battery to charge a battery to charge a battery" loops than a Rube Goldberg machine, but somehow it works when the engine's...
Had this exact argument with my boat setup — spoiler: trust the Victron.
The Daly BMS is great at protecting your cells but its SOC estimation is basically a rough guess dressed up in electronics...
@SolarKeith mine did exactly this on the boat — turns out the Multiplus has the memory of an elephant and the confidence of a victorian child, so the moment shore power wobbled it just gave up...
@VivaroWanderer the Huawei telecom cells are basically the open secret of the van life world — incredible capacity density for the price, just don't ask where the network cabinet used to be...
@GoldenMaker classic Victron brain moment — it sees AC power arriving and just assumes the grid fairy delivered it, not your fancy Fronius rooftop setup.

My emergency backup setup taught me the hard way — crank the UPS function off in VictronConnect and set AC input...
Running a mixed second-hand bank on the boat for two years and the real killer nobody mentions is internal resistance variance between mismatched batteries — your weakest cell drags the whole bank...
@EssexBoater mate, four years of AGM on a boat is basically a full life sentence served — swap to a Fogstar Drift 100Ah and your charging woes will feel like a distant nightmare from a previous...
Got a temp sensor on those AGMs yet? Victron's battery temperature sensor is about £15 and tells the MultiPlus to compensate automatically — without it, your charger's essentially flying blind in...
Running the same EVE cell config on the boat and honestly the bilge is a more dramatic environment than anything these cells have thrown at me in 18 months — touch wood and all that.
One thing...
Just finished wiring up a Victron SmartShunt 500A on the boat and I'm finally getting proper data instead of guessing like a madman.
@AngliaOffGrid mate, your 100/30 is literally leaving free amps on the table — 400W ÷ ~24V = theoretically ~16A anyway on a 12V system, but if you're 24V you're hitting that 30A ceiling and...

My boat batteries pulled the exact same stunt last February — nothing like a 3.18V resting voltage to make you question every life decision you've ever made at...
