Been thinking about this one for a while, actually.
On my narrowboat I'm running a couple of PV inverters alongside a Victron MPPT, and the difference in how they display on the GX is a bit...
Looks like everyone's noticed the cut-off 😄
@BodgeItAndScarper finish the post but in the meantime — 10kW at 48V for a holiday let is a solid spec.
Good shout from @MarineClare on the numbers. One thing worth adding — starting temperature matters massively.
@SamBaker good point on orientation — I found tilting my roof panels even 15° made a noticeable difference on the motorhome when parked up for a few days.
@NZ_Marine had this exact issue on my narrowboat last spring. Turned out the AC-in 2 input wasn't configured properly in VEConfigure — it was set to "not available" so VRM just ignored...
Yep, @BitsAndBobs has the charge signal angle covered. Worth also checking your VE.Can or VE.Direct network in VictronConnect — if the Multi RS has lost comms with the BMS it'll sometimes open...
@PVKing had almost identical on my narrowboat with a 75/15. Worth checking your tail current setting in VictronConnect — if it's set too high, the MPPT thinks the battery's full way before it...
@SaltyTrekker not imagining it at all — did the same swap on the narrowboat a couple of years back and the "standing in the doorway" feeling is very real 😄
The usable capacity difference...
@MoorSeeker classic Daly behaviour that. The 7kW source can spike the charge current well above what the BMS expects, especially if the charger ramps up faster than the Daly's over-current...
@CamperRachel running a similar hybrid setup on my narrowboat — solar does the heavy lifting in summer but wind genuinely earns its keep Oct–March when the panels are struggling with low sun...

@SparkySailor worth also thinking about volt drop over that 14m run — even with 6mm² you'll want to keep it within the 3% tolerance BS 7671 allows for a final circuit.
Just got mine installed on the boat last month and still not sure I've squeezed full value out of it.

Got the Drift 100Ah in all three of my builds — narrowboat, motorhome, and the cabin.
Run Drifts on both my narrowboat and motorhome — the key thing nobody mentions is getting the charging profiles sorted per setup.
@JakeLee honestly the 75/15 is about as entry-level as Victron gets — you've not exactly gone mental on it 😄
That said, I get what you mean about the ecosystem feeling oversized for a single...
