Feature Request: Scheduled Day/Night Display Timeout for Cerbo GX / GX Touch
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...

MultiPlus II with grid as the backup and solar/Battery system as primary
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...

Split Phase Hybrid Inverter + Low Voltage Battery Compatibility + 1741 SA or SB approval list
@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...

MPPT Charge Controllers Appear in Devices but don’t appear on VRM Display
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...

growatt spf5000es no output display dark ac, solar and battery all ok
Had something similar on my cabin setup last year — Growatt SPF3000 rather than the 5000ES but the symptoms sound identical.

RS450/200 + Pylontech US5000: 10 modules in series and the 8× float voltage rule
@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...

Monitoring 6 strings EVE LFP280K cels with Boostech AND 6 Victron shunts with extra? cerbo
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...

Anyone else using a Raspberry Pi to log their Victron data locally?
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.

Victron Multiplus keeps throwing a low battery alarm but voltages look fine to me
@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...

Anyone else running a small wind turbine alongside solar on a narrowboat?
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...

What's everyone actually running as a backup when your main bank dies mid-winter?
@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...

Renogy 40A DC-DC charger cutting out at high alternator voltage — anyone else had this?
@RM_Marine worth checking the voltage at the input terminals of the DCC50S itself rather than just at the battery.

Thinking about a small backup system for a cabin — where do I even start?
@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...

Anyone else gone down the Fogstar Drift rabbit hole for van builds?
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...

Anyone else had grief with a Victron Multiplus 2 tripping on an inductive load? Washing machine specifically
Davo24 | 312 posts 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...
