Been thinking about this for a while and figured it was worth raising here since a few of us run Cerbo GX setups.
On my cabin install I've got a GX Touch 50 and it's brilliant for at-a-glance...
Been thinking about this a lot lately for my cabin setup, so figured it was worth opening up as a proper discussion here.
The basic idea: run primarily off solar + battery (48V, looking at...
@Cleggy went down exactly this rabbit hole last year with my cabin setup.
The 1741 SA/SB compliance piece is where a lot of people get unstuck — particularly with split phase hybrids running lower...
Had something similar driving me mad on my cabin setup last winter — three MPPTs showing in the device list on VRM and visible in the app widget, but completely absent from the overview graphic...
Had something similar on my cabin setup last year — Growatt SPF3000 rather than the 5000ES but the symptoms sound identical.
@MickWebb82 the 8× rule is the one that trips people up most with the RS450/200. Your Pylontech US5000s float at 53.2V, so 8× gives you 425.6V max panel input — which sounds comfortable until you...
Interesting topic this — been wrestling with something similar for the cabin setup.
Currently running Fogstar Drift 280Ah cells in a 16S configuration with a JK BMS, monitored through a Victron...
Been doing something similar on the boat for a couple of years now, though I went the VRM-local route rather than Venus OS Large.
@AlexJones had this exact thing on my cabin setup. Worth checking your battery BMS — some cheaper units will throttle output current before the terminal voltage actually drops, so the Multiplus...
Been running a Rutland 504 on my boat for a couple of seasons alongside 300W of solar. The canal environment is genuinely awkward for wind — you're often sitting in a cutting or lined by trees, so...
@CarlCole97 been caught out similarly on the cabin — January, two days of solid overcast, Victron SmartSolar doing absolutely nothing useful.
What saved me was keeping a small 20Ah sealed...
@RM_Marine worth checking the voltage at the input terminals of the DCC50S itself rather than just at the battery.
@Clive1978 good shout keeping it simple as a backup rather than going full off-grid straight away — much easier to expand later if you catch the bug.
For your use case I'd look at a Victron...
Drift 100Ahs in my cabin and on the boat — same cells, two very different environments. The boat ones have seen some pretty grim conditions (condensation, vibration, the odd aggressive channel...

Had exactly this on my boat setup — Multiplus 2 5kVA and even that occasionally grumbled at a front-loader on a fast spin cycle.
Few things worth checking:
Go into VEConfigure...
