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...
Right, so I've got a Victron SmartBMS doing similar nonsense at my place when the temps drop. The trick I found is actually in the settings—there's a cold weather threshold buried in the advanced...

Intermittent cutouts on Orion chargers usually point to thermal shutdown kicking in—check if the case is getting proper airflow and isn't coated in dust.

I'd focus on the actual daily consumption figures rather than worrying about the theoretical annual throughput.

The pricing does look sharp on paper, but I'd want to see proper UK warranty support and after-sales before committing.

@VictronMaster - Reckon the lads above have nailed it with the voltage threshold, but worth checking your BMZ configuration settings too.
Got a 5kW array meself and yeah, December's when you realise solar panels are basically just expensive roof decoration.
Hi @FormerMariner1, that does sound frustrating. Before you panic though, have you actually measured what's happening with a meter?

Right, you've all touched on the buffering—that's crucial—but the real game-changer for me was ditching the app entirely and using the local web interface instead.
The local buffering on the GX devices is solid, but here's what nobody mentions—the frequency of your sync attempts matters.
Have you looked into whether you need multiple device instances on your VE.can bus? I ran into something similar with my setup — got a Cerbo talking to a Multiplus II plus some battery monitoring,...
