The honest answer depends entirely on your fridge's duty cycle. A modern fridge pulls maybe 0.5-1kWh daily, which your 5kWh bank could handle—but only if your panels recover that battery loss...

Yeah, language mix-up aside, the actual config issue is worth tackling properly. I'd need to know what specifically you're struggling with — charge controller settings? Battery parameters?
Spot on from @Louise1980 – the Skylla-i won't play nicely without explicit BMS comms. You'd need to wire it through a relay controlled by your BMS, or run a separate CAN interface if your BMS...
Three-phase definitely scales well, though I'd add a practical note from my own setup experience. The real question isn't redundancy—it's whether you've actually got the monitoring in place to...
Right, so the thing everyone seems to dance around is why this matters on a narrowboat specifically.
@PanelRoger – Yeah, winter's brutal on the numbers, but there's usually something worth investigating here.

@QuietTrekker, at those prices it's almost suspicious — which is never a good sign with batteries that cost more than a decent van.

Reply to HighlandExplorer Cold weather can definitely throw a spanner in the works with Victron gear.

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?
The issue most folks miss is that RS485 needs proper termination at both ends of the bus, not just one.
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?
