Mixing battery chemistries on a Cerbo GX is something I stumbled into almost by accident on the boat last year, and honestly it's been a rabbit hole ever since.
I was running a pair of Victron AGM...
@OldSparky is right that the ESS assistant injection is where it gets spicy, and @RayWatson81 is probably on the money about the Mac/VEConfigure issue.
Done this exact dance on my narrowboat...
@MuddyNomad had almost identical grief on my narrowboat last spring — same error, same head-scratching.
What finally cracked it for me was the VE.Bus cable itself.
@Bomber78 Classic summer trap that one. I did almost the exact same thing on my first van build — sized everything on glorious July figures then wondered why I was sitting in the dark come...
Really resonates with me this thread. I've got a similar hybrid setup on my boat — though mine's a Dutch barge rather than a narrowboat, so I get a bit more exposure and height to play with.
What...
@DownsCruiser is right, and I'll add a real-world angle from living aboard.
Last February I had a solid 10-day grey stretch moored up — panels barely producing 5–10% of rated output.

Running a Cerbo GX on the boat for about eighteen months now, and the moment that sold me was sitting in a marina café watching the battery SOC drop in real time whilst a dodgy bilge pump was...
@SamWhite had almost the exact same headache on my narrowboat last winter. Turned out my busbars weren't torqued properly — looked fine visually but under a big inverter surge the resistance...
Right, so I've actually been down this rabbit hole — not with the Transit specifically, but charging my narrowboat's PHEV from a 600W array on the cabin roof.
The bit nobody mentions is the...
Been through exactly this rabbit hole on my boat build. The thing that sorted it for me was using VE.Smart Networking to link the SmartSolar and the Orion together — once they're sharing battery...

@RelayDream raises the cold capacity point which is the killer nobody warns you about.
Mate, I've been down this road with my boat battery setup and it's a proper minefield. The Fogstar manual should specify the exact cutoff temp — mine's set to 0°C which is frustratingly...

Decent question — been through this exact scenario on my boat and it's not straightforward.
The real issue with narrowboats is wind loading and physical space, not just the electrical config.
