@BoatPaddy worth checking whether your panels are actually wired for the highest practical Voc too. On the boat I found that running two panels in series rather than parallel made a noticeable...
Got my first Victron MultiPlus 12/3000 installed last weekend in the static caravan — proper job, or so I thought. Everything looked perfect on paper.
DodgyCaptain | 312 posts Different application here — running a Victron SmartSolar on the narrowboat — but cold morning sluggishness was an issue until I moved the controller inside the cabin...
Interesting one this — slightly different situation to the usual "charge leisure from alternator" setup most of us deal with. Got me thinking about my shepherd's hut build actually,...

@NotAnElectrician had this exact nonsense on my motorhome rig — turned out the PV array open-circuit voltage was sitting just under the MPPT's minimum startup threshold because I'd wired two...
@ZFS_OffGrid worth ruling out ground loops before you go chasing cables or firmware. If your Cerbo and SmartSolar are pulling their negatives from different points in the system, you can get all...
Had this exact problem on the narrowboat last winter — SmartSolar 100/30 kept dropping out of Bluetooth overnight, usually when temps dropped below about 4°C.
@PanelLouise the orientation thing on boats is even more of a headache — my setup has panels on a tilted stern arch and flat ones on the coachroof, completely different irradiance profiles...
Has anyone else had issues with a Victron Cerbo GX misreading battery state on a 24v lithium setup? Running a fairly standard van build — 24v system with Fogstar Drift 200Ah cells, Victron MPPT,...

Went through this exact palaver last year swapping out the knackered lead acid in my tiny house setup for a Fogstar 100Ah LiFePo4 — best thing I ever did, but the emergency brake side of things...
WillHall | Posts: 412 Great thread @PeakNomad! I've been running Venus OS Large on a Pi 4 for about eight months now and it's been rock solid.
@EcoFlowMaster done exactly this on my narrowboat — ran both for about six months thinking the relay gave me a useful backup.
@HeatherWalker VE.Direct is fine but if you've got a Cerbo GX already you're just duplicating work. That said, I run a Pi Zero 2W in the shepherd's hut pulling MQTT from Venus OS — logged 14...
PaddyDixon61 | Posts: 312 Had almost this exact setup in my motorhome last year. Orion XS in monitor-only essentially means the Cerbo can see it but DVCC won't actually push CVL/CCL down to it —...

Something worth flagging that I don't think's been mentioned yet — make sure your DC cabling between master and slave is absolutely symmetrical in length and cross-section.
Good shout from @MrBodge73 on PowerAssist — saved my generator's bacon more than once when the batteries decided they were hungry and I had loads running simultaneously. One thing worth adding: if...
VitoProject | Posts: 1,156 @Rob1963 that "enthusiastically redistribute" comment made me laugh despite myself — seen similar.

@BigAl the rabbit hole is real — I spent three weeks convinced my Multiplus was faulty when it turned out I'd just not set the correct battery preset 😅 One thing that genuinely helped me was...

@ZFS_OffGrid worth checking the firmware on the SmartSolar itself — I had a similar gremlin on my garden office setup (150/35 talking to a Cerbo GX) and it turned out the MPPT was running firmware...
Petrol goes stale faster than my enthusiasm for rewiring the shepherd's hut in January — kept a small Honda EU22i for the cabin and the carb gummed up after one lazy summer of neglect. Sta-Bil in...
