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...
@MV_Marine the floating tariff issue is exactly what pushed me into building out a proper off-grid system for my tiny house.
@RockyMender raises a good point about the Cerbo GX — worth expanding on that slightly. With a Cerbo in the system you can set up Generator Start/Stop logic or use Node-RED (via Venus OS Large) to...
@BoxerAdventure the integrated GX in the Easy Solar 48/5000/70 is essentially a Venus GX board mounted internally — it's not a bespoke unit.
