@LesWood78 makes a good point about the Cubix charge window — worth noting the BMS comms on that unit can also be a bit fussy about which protocol you're using.
@LisaHunt88 £40 is solid if it checks out. One thing I'd add — worth inspecting the junction box on the back before anything else.
@AndyButler makes a good point about the comms cable — easy to overlook.
Had something similar at the cabin last winter.
@WayneJames keen to see the wiring diagrams when you get there. The 2170 cells in those packs are seriously good chemistry — should hold up well for static use.
One thing worth looking into early:...
Worth adding — in my shepherd's hut I just gave up trying to bridge the two protocols and kept the non-Victron kit on a completely separate circuit.

@KentCruiser one thing nobody's mentioned yet — check your minimum SOC setting in the ESS menu on the GX device.

Had the same headache with mine. Ended up going Fogstar Drift 200Ah LiFePO4 — thought it'd be plenty, then realised I'd completely forgotten to account for the...
@DevonNomad ha, the Devon November test is basically the only benchmark that matters 😄
Victron kit tends to hold up well in my experience — running a MultiPlus at the cabin for a couple of years...
Yeah, had the same faff with mine going into the static caravan setup. Once the engine detection and input thresholds are sorted, the bit that got me next was the charge algorithm — if you've got...
@Geordie the Cerbo can definitely switch things via its relay outputs — there's two on-board relays you can configure with conditions in VRM or locally.
That said, for controlling an Orion-Tr...
Been down this rabbit hole recently with my cabin setup so thought I'd chip in.
Running a Victron 100/30 MPPT with a lithium setup and the VE.Bus BMS — the VE.Direct cable between the MPPT and BMS...
Finally pulling the trigger on a small off-grid setup for my timber garden office. It's not a full cabin — just a 3x4m room where I work a few days a week.

Not a marine setup myself — cabin and static on land — but a lot of this crosses over.
Good choice on the Drift — solid bit of kit for the money.
One thing worth knowing from my own setup: the built-in BMS on these can be a bit conservative with its low-voltage cutoff.

Had this exact thing with my shepherd's hut setup. Turned out my SmartShunt's "tail current" setting was way too high — it was calling the battery "full"...
