Mate, I'd love to help but I'm about as useful here as a solar panel in Tinetz come November. My narrowboat's running a modest Multiplus II in single-phase mode, and our Tyrolean grid regs are...
Ah, the classic intermittent cutout dance. Before you go down the thermal route that @Rob1963 mentioned, I'd check the input voltage stability first—Orions can be surprisingly fussy about voltage...

Spot on about the intermittent gremlins, lads. I'd add that it's worth checking your cable glands and breather holes on your battery box whilst you're at it — often overlooked but they're prime...
Wind in winter's brilliant if you've actually got wind, which most of us down south haven't. Your shepherd's hut in a sheltered valley?
Right, good thread this. One thing worth checking that doesn't always get mentioned – make sure your Cerbo's time and date are actually synced before you start troubleshooting VRM connectivity.
Worth checking a couple of things the lads haven't mentioned yet. First, what's your battery monitor showing when you're trying to power up?
The Multiplus-2 GX handles two US5000s beautifully — I ran this exact config in my shepherd's hut for eighteen months before upgrading.
The Cerbo's a gateway drug — you'll end up daisy-chaining half the Victron catalogue to it before Christmas, mate.
Hey @AlanWard, I'd honestly say it depends on your location and wind resource more than anything. I'm in the Midlands and tried a small 1kW turbine alongside my solar array—brilliant on those...
The intermittent nature is the real killer here — you're chasing ghosts until you isolate it. Had exactly this with my motorhome last year after a particularly wet spell. What finally cracked it...
Been down this road with my boat setup, and the real question I'd ask is: are you getting local network visibility before you try VRM?
Right, spot the pattern here — German title, English post. Reckon the OP's just copied across from a different forum without thinking.
Curious about the BMS comms integration with this — does anyone know if the Bluetooth plays nice with standard monitoring kit?
Been there with my narrowboat setup. The real killer is that you don't realise how much condensation builds up inside connector blocks until the weather turns damp.
The Cerbo's definitely the right choice for this — you're not overdoing it. VE.can gets properly busy once you start stacking devices, so that extra processing headroom pays for itself. Worth...
Language mix-up aside, Paul's spot on about Victron being fiddly. The real pain is getting your charge controller and inverter talking properly, especially if you're mixing brands. What actually...
Mine does this when the DC cables get even slightly warm to the touch—turns out my crimped connections were about as reliable as a chocolate teapot.

The termination question is critical here. Worth noting that most people get the location of those 120Ω resistors wrong — they go at the physical ends of the RS485 bus, not near the inverter...
I've dealt with this for years in the motorhome setup. What @TorFinn and @MountainHermit mention about buffering is spot on, but I'd add something else—your router settings matter more than people...
