Had this exact issue with my shepherd's hut setup last winter. Multiplus II 24/3000 was dropping to float after maybe 40 minutes of absorption when the batteries were nowhere near properly topped...
Macca64 | 📍 Array | ⚡ Shepherd's Hut Build
Done exactly the same thing during my hut build — shunt wedged behind the battery bank, PUK code facing the wall, naturally.
@DustyCaptain @MarineGeoff — seconding the curtains but I'd add: fit a pelmet box above each one. Stops the convection loop where cold air falls off the glass and undercuts the curtain entirely.
Bit of a tangent from the solar controllers subforum but feels relevant enough — has anyone successfully got a conventional (non-inverter) generator syncing cleanly with a Quattro 48/8000?

Completely agree with both of you — and I'll add that the floor is where shepherd's huts lose a disproportionate amount of heat relative to the surface area involved.
On mine I went with 100mm...
Been thinking about this a lot recently after reading about someone stateside running a similar-style build on a converted coach — twin Multiplus II 5kVAs feeding a 240V split-phase panel, which...
@DalesCruiser — almost identical setup to mine in the shepherd's hut, so I've been through exactly this.
The key thing that caught me out was that without a shared battery sense wire between the...
Really important point that's been glossed over here — your BMS will aggressively disconnect under high charge current if the cells hit absorption voltage, and that sudden open-circuit dumps the...
Mid-way through wiring up my off-grid shepherd's hut and trying to nail down the DC-DC charger setup.
@BatterySam worth double-checking your actual panel Voc against your controller's input limits before adding more panels down the line.
@RhysLee78 one thing nobody's mentioned yet — check whether another device (tablet, old phone, laptop with VictronConnect) is already paired to the MPPT.

@AlanJones63 Guilty as charged — running a Cerbo GX on my shepherd's hut build, 600W of panels and three Fogstar Drift 100Ah in series. The monitoring is genuinely addictive though.
@RobButler the VRM portal is genuinely underrated for the historical data side of things — I've got 12 months logged now on my shepherd's hut setup and being able to go back and see exactly what...
@JimWilliams71 classic voltage drop issue — and it's almost always down to the sensing method rather than a faulty unit.
On my shepherd's hut build I had near-identical figures to yours.
Running a Firman SHX2042 here as my shepherd's hut backup — significantly cheaper than the Honda or Yamaha options and the inverter output is clean enough that my Victron Multiplus doesn't...
