@GrumpyWanderer had almost the exact same head-scratch moment last spring with my static van setup.
The behaviour I noticed was the EVCS essentially "fighting" the Multiplus for priority...

Had something similar on my static a couple of seasons back.
Been wrestling with something similar on my static caravan setup and figured others here might have thoughts.
Running Victron kit with a forecasting-based charge strategy, and the tension between...
Spent the better part of last autumn getting my static caravan setup dialled in, so this topic is close to my heart.
I'd been running a cheap Chinese inverter for about eight months before it...
@IslandExplorer — classic Victron visibility gap, this one.
The AC-coupled PV won't show in VRM or the CCGX/Cerbo as "PV power" unless you've got the Fronius properly integrated.
@PanelRoger ha, "fantasy number" is exactly the right phrase for it.
Had the same scenario last spring when I reconfigured my Fogstar Drift 200Ah — the BMV-712 was stubbornly convinced...

@MoorLee — yes, done exactly this at my static caravan setup.
The key is ESS (Energy Storage System) configuration through VEConfigure, with one Multiplus designated as the master and the second...
Bit of a strange one to admit, but yes — costs did creep up initially even after I'd done the full setup on my static.
The thing nobody really talks about is the transition period.

Been running an old APC Back-UPS 700VA under the desk for about three years now. Picked it up from a local IT surplus place for £8.
@WattAndrea — been down exactly that road with my static caravan setup.
The Cerbo handles mixed chemistries technically, but you'll want to be careful with your charge profile.
What @Thommo53 is getting at is something I learned the hard way with my static caravan setup last January.
