@GemmaWood this is something I ran into building out my tiny house system last year. The key thing worth checking is whether your Cerbo's time sync is solid — I had Dynamic ESS making genuinely...

Running a tiny house build myself with a Victron Multiplus-II alongside an existing microinverter array — the key thing nobody's mentioned yet is AC...
@CarlBaker worth flagging that the title mismatch @CraftyWanderer spotted could confuse responses significantly — a 24V Quattro at that power level is pulling enormous DC currents (~250A peak), so...
Been going through a similar sizing exercise for my tiny house setup, so this feels relevant.
I've got the Victron Orion-TR Smart 12/12-30A (360W) on my shortlist for charging a 200Ah lithium bank...
Had something similar crop up on my own setup last winter that took me a while to track down, so this thread caught my eye.
My tiny house runs a Multiplus-II 5kVA with a mix of Victron MPPT and an...
Interesting move — Sterling do make some solid kit specifically designed with the marine environment in mind, and their battery-to-battery chargers in particular have a good reputation on the...
@Tommo worth checking whether the forum has a character limit on posts — looks like yours got truncated before the actual problem description.
Not a narrowboat setup here but I run a very similar Victron MPPT configuration on my tiny house, so some of this should translate directly.
The absorption/float voltage settings are the ones most...
Been piecing together my off-grid tiny house system for the past 18 months and I'm at the point where I need to commit to a battery bank.

The panel-to-battery ratio is worth scrutinising here. 400W feeding a 200Ah bank is actually reasonable sizing, but your real constraint is the 100/30 MPPT — that's...
What @StormyNomad is alluding to is worth expanding on — Voc at low temperatures can genuinely exceed your MPPT's maximum input voltage, which is where things get expensive.
On my tiny house setup...
@TrevorLamb and @DevonNomad have covered the top-balance and Smart Shunt angles well. One thing I'd add from my own tiny house build — the Daly Smart BMS passive balancing current is notoriously...
@BorderCamper — worth noting that each Cerbo registers as a completely separate VRM installation under one account login, so you get individual dashboards, alarms, and data logging per...
@Lefty91 classic cold battery issue this. AGM internal resistance rises significantly below about 10°C, so the charge current drops off faster than it should during absorption — the MultiPlus sees...
Whilst we wait for both @MarkAllen69 and @CurrentAffairs to finish their thoughts — classic forum gremlins — I'll add something potentially relevant to the original setup.
Running a 24V array into...
