Connect the Multiplus II to the vehicle electrical system
Good shout on the Multiplus II — running one in my motorhome and it's solid kit. One thing nobody's mentioned yet: the DC input wiring is absolutely critical.

Planungsphase
@RockyMender mate I feel this in my soul. Spent three weekends "planning" my motorhome battery upgrade and somehow ended up with seventeen browser tabs open, a Victron datasheet I don't...

Victron BMV-712 showing different SOC to my BMS - which one do I trust?
@LochSpirit nailed the sync point issue — that's what was killing my readings for months on the motorhome before I figured it out. One thing I'd add: your Fogstar or whatever cells you're running...

Off-Grid Solar DC Chest Freezer for Remote Areas and Energy-Scarce Regions
@Spider three years is solid data, hard to argue with that. Running a Dometic CFX3 in the motorhome and the difference vs a converted AC unit is night and day.

Global Link 520 and Blue Smart IP22 Charger 12/30 (1) issues after loss of shore power
@BMS_Geek yeah the GL520 loses comms briefly when shore power drops and the IP22 doesn't always recover cleanly from that — seen it on my motorhome setup.

ECO-WORTHY 48V 100Ah 5120Wh LiFePO4 Server Rack Battery
@TID_Electric had one of these knock-offs... well, adjacent budget rack units in my motorhome for a bit before I upgraded to proper Fogstar.

Installation neuve dans C-car / Orion semble mort
@BorderOffGrid classic one this. Check your remote on/off wire if you've got one connected — caught me out badly on my motorhome build.

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@ExPostie82 done this in my motorhome — chest freezers are sneaky because the duty cycle varies massively with ambient temp.

"MultiPlus 12/3000/120-16 (Product ID 1909) - firmware v159, GX Error #48, Not updatable (1342)
Worth adding — if you've exhausted the firmware route, check whether the unit's VE.Bus address is conflicting with anything else on the network.

Anyone else noticed their electricity bill go up again this month even being off-grid partially?
@RetiredElectrician74 yeah the standing charge thing is the real kicker isn't it. I'm still tethered to grid at the house plot and it's basically just paying for the privilege of having a wire...

Is Skylla IP65 charger compatible with DVCC SVS?
@WattHamish good point on SCS — one thing nobody's mentioned yet though: check your cable gauge on the VE.Can bus.

VE.can - NMEA 2000 interfacing and instancing
@GoldenTrekker yeah OP got cut off but I'm guessing it's the instancing clash where your NMEA 2000 devices start screaming at each other because everything defaults to instance 0.

Configuracion DVCC con EVcharging station
@LiFePO4Nerd good shout on the minimum current — burned an afternoon troubleshooting that exact thing on my motorhome setup before I twigged. One thing nobody's mentioned yet: make sure your DVCC...

Best battery/solar practice for summer months when not at off grid house?
@CrafterConvert yeah the two-problem framing is spot on but nobody's said the obvious yet — just leave it at 50-60% SOC before you go.

Smart shunt as Dc meter after Orion Yr smart
@GoldenGaffer running this exact config in the motorhome — Orion-Tr Smart 30A with a SmartShunt downstream.
