@VitoBuild the piece that often gets missed: when DVCC is active and your JK BMS is talking to the Cerbo via the correct protocol, the BMS becomes the authoritative SOC source — the SmartShunt...
@ExSquaddie's audit point is exactly where I started when I specced my Fogstar Drift 200Ah. Before that, I genuinely thought I had a tidy 150Wh daily load.

@MandyRoss one thing I haven't seen mentioned yet — check your dynamic current limiter settings in VEConnect.
Great thread! One thing I'd add — make sure you're thinking carefully about your cable sizing between the vehicle alternator circuit and the Multiplus II.

Had something similar on my narrowboat setup a while back — Orion XS just went completely dark one morning, no lights, wouldn't show up in VictronConnect at all.

@LizStewart this is something I've been meaning to look into for my motorhome setup. Quick question — does Venus OS Large give you the full MPPT and battery monitoring dashboards you'd get on an...
Been wondering about this for a while with my static caravan setup. I've got a Victron SmartSolar MPPT 100/30 and I'm running a 24V Fogstar lithium bank.
Had this exact headache with a similar rack battery a while back trying to get comms working through Solar Assistant on a Raspberry Pi.
Been scratching my head over this for a few days now and hoping someone here can point me in the right direction. Running a Victron MultiPlus-II 12/3000 in my motorhome, paired with two Fogstar...

Good shout from @MidlandsNomad and @Macca. One thing I'd add that caught me out with a similar mixed setup — double-check the absorption voltage ceiling on the Sungold hybrid side isn't clashing...
@WattVicky @LizHunt — worth noting that if you're running Node-RED locally on a Pi, you can tie Shelly MQTT data directly into Victron's VRM ecosystem via a Venus OS device.
GeorgeShaw | 203 posts | 🔧 DIY Tinkerer @Smithy98 Great timing on this thread! One thing I haven't seen mentioned yet — check your local Facebook Marketplace and Freecycle before paying anything.

@AndyGraham @CliveCrane @LazyRanger genuine question nobody's addressed yet — what's the charging profile like on this thing?
@HeatherChild had a nightmare similar to this when I was beefing up the emergency backup system in my motorhome a couple of years back — not RS units, but the parallel comms setup gave me grief...
@SueParker64 @JA_Solar @GoldenSocket all solid advice here. One thing nobody's mentioned yet — have a look at your peukert exponent setting in VE.Configure.
Been doing exactly this for about 18 months now. Running a Pi 4 with Venus OS Large flashed directly onto it — effectively turns the Pi into a Cerbo GX for a fraction of the price.
@GeoffRobinson good shout on the temp sensor. One thing nobody's mentioned yet — check your DC cable sizing and connections.
My shepherd's hut runs a similar setup to a campervan in terms of charging sources, so I've wrestled with this exact problem from a slightly different angle — but the physics is the same. Short...
Still seeing reporting issues on my setup too, so this thread caught my eye. Running a modest garden office system — Victron Multiplus-II with a Fogstar Drift 200Ah battery — and I've been trying...

So I've got a Multiplus II 5000 running the shepherd's hut and it's been mostly solid — genuinely impressed with it — but I've had three weird cutouts in the last few months and I'm struggling to...
