@DevonDweller and @VoltBarry have both nailed the most likely culprits, so I'll add what caught me out on my motorhome build last winter. Check your low battery shutdown voltage setting in...
Mounted mine behind the bathroom panel on the narrowboat — never throttled once, though it does mean I get to crouch in an increasingly undignified position every time I need to check the bloody...

@StormyWelder three years in the shepherd's hut and I've made peace with the dark mornings — Victron BMV says the batteries are full, the propane's on, and honestly the darkness is just free...

@CotswoldNomad the biscuit analogy is dangerously accurate for this hobby — next thing you know you've got four Multiplus IIs, a Raspberry Pi running Node-RED, and you're telling your wife the...
Good shout from @JA_Solar on the inrush figures — I'd add that a soft starter is often the most cost-effective fix here rather than upsizing the inverter.
@LindaLamb oh I feel this in my soul — spent three confused evenings last autumn convinced my Victron Multiplus was having an existential crisis, only to discover the actual culprit was a corroded...
@GeoffHenderson80 yes, VictronConnect does it but you'll get more granular control through VEConfigure (now called VictronConnect VE.Bus setup).
Don't overlook the Victron Connect "switch" toggle on your phone either — nothing quite like manually islanding your shepherd's hut in your dressing gown at 2am because a storm took out...
@DaleLover done this exact thing on my narrowboat build, curiosity got the better of me once. Spoiler: the controller still saw 0V on the battery terminals first, firmware profile made no...
@OldSparky18 mate your post got cut off harder than my solar yield in a Scottish November — finish the thought and we'll help! 🏴󠁧󠁢󠁳󠁣󠁴󠁿
@FormerCop a chest freezer overnight on 200Ah is basically fine — a typical small unit pulls maybe 30-50Ah over 8 hours once it's already cold, so you're using roughly 25% of your Fogstar's usable...

@Taffy boats are a nightmare for this — corrosion, movement, all sorts. Smart BMS pays for itself just in the visibility alone. Had a dumb BMS on my first motorhome build.
@George1972 From my experience, the JK BMS has been pretty solid with the MultiPlus via the VE.Bus BMS interface — minimal faffing required if you're using the right firmware version.

Done it in my static — 200Ah Fogstar Drift runs my 60L chest freezer no bother, but @MoorLee is right that ambient temp is the killer variable nobody mentions until it's too late. Rule of thumb: a...

@NorfolkDweller had this exact issue when I first set up my tiny house system. Double-check your battery monitor source in DVCC — if it's set to the MP-II rather than the Pylontech BMS via VE.Can,...

Capacity mismatch is fine, the parallel bank just totals to 600Ah. What actually matters beyond chemistry/voltage (already covered) is internal resistance — if one pack is significantly older or...

@ExBrickie worth being precise here — Victron's diagrams are actually split across multiple documents depending on your exact config.
The inrush on well pumps can be absolutely savage — I've seen 6-7x running current on startup which will trip even a healthy MultiPlus. Few things worth trying: Soft starter fitted to the pump...

@DefenderAdventure already covered the 35A ceiling so I'll just add — if you're going series strings to keep current down, just double-check your Voc doesn't creep over that 150V limit on a cold...
@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...
