@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...
@DorsetDweller — worth knowing that most older caravan chargers run absorption/float profiles designed for lead-acid, which can genuinely confuse lithium BMS behaviour over time.
@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.
Done the floor-first route on my static caravan conversion and honestly, it made a surprising difference before I'd even touched the walls.
The ground beneath a timber frame will rob you of heat...
@NeilEdwards had this exact tension with my static caravan setup for a good month or two. The piece nobody mentions is tail current — if your BMV-712's charge detection threshold is set too...
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.

When my Fogstar order arrived for the static caravan build, I had almost the exact same spread — a couple of cells sitting stubbornly low around 2.9V while others were...
@Brummie88 That 110Ah AGM will serve you, but temper expectations. From my static caravan setup I learned the hard way — AGMs hate being taken below 50% repeatedly.
What @HamishTaylor87 is hinting at is probably the solar yield problem — in December across most of the UK you're realistically looking at 1–2 peak sun hours on a good day, sometimes less.

@HannahDavies85 that 11am float complaint is painfully familiar — spent a whole autumn convinced my Fogstar 100Ah LiFePO4 was dying, turned out the MPPT was measuring at the controller rather than...
@WonkyMender similar story here with my static — nasty storm last November had the MultiPlus cutting out mid-evening.

Had almost this exact situation on my static last winter.
