@VanJulie same issue on my static van — Victron MPPT + Cerbo but a non-Victron inverter and the flow diagram just looks broken/incomplete.
What I ended up doing is using Node-RED on the Cerbo to...
Got a Brass Monkey 35L running off my static caravan setup — similar situation. Rough rule of thumb I use is assume the freezer pulls maybe 30-40% of its rated wattage as an average draw over...
Not a motorhome but my static caravan setup taught me loads about exactly this. Short winter drives won't cut it — the alternator barely gets going before you're parked up again.
Worth looking at...
Been doing this for about 18 months now in my static and honestly it's been brilliant. Running a Pi 4 with Venus OS Large on it — pulls everything off the Cerbo GX via MQTT and shoves it into...
Had this exact headache with my static van setup last summer. Both were showing wildly different numbers and I didn't know whether to trust either of them.
Short answer — trust the BMS for...
Glad I made the jump to off-grid when I did tbh. My static caravan runs almost entirely on solar + Victron kit and I dread to think what I'd be paying otherwise.
Saw my neighbour's bill last week...
Had a similar situation with my Victron Smart Lithium 12v 100Ah last year — got it installed in the static and started poking around in the Victron Connect app out of curiosity.
Worth knowing that...
@SophieClark the grounding thing tripped me up too when I fitted mine in the static van. Key thing in non-isolated mode — your chassis grounds need to be properly bonded together already,...

Same issue hit me on the 200A unit in my static. Rolled back to 11.19 and it's been solid since.
@LakelandSolar yeah this is totally normal mate — cold panels actually perform better than hot ones. Something about lower cell resistance means higher Voc.
Yeah, the relay issue is real. Had the same setup in my static before I knew better — relay just sees "voltage high enough, connect" and your LiFePO4 just sits there half-charged...

@SussexDweller done this with my static for about a year now. Key thing nobody mentions — schedule your charging around surplus, not convenience.

Had similar issues with mine in the static caravan last winter. Turned out it was a combination of things worth checking:
First, the obvious bits:
Is the Multiplus actually set to inverter mode?
