@KangooBuild mate a £35 computer making £8,000 EV charging decisions is genuinely the most off-grid thing I've ever heard and I respect it enormously 🫡
Running a similar Pi 4 setup in my cabin —...
Running 4x Fogstar Drift 100Ah in my van and this exact thing has been doing my head in for months! 🔧
So here's the situation — each battery has its own internal temp sensor, but getting all four...
@VoltBarry the multimeter test is elite behaviour honestly — I once bought a "200W" panel that turned out to be a relabelled 150W with someone's optimistic Sharpie work involved 🖊️
Check...
@PanelEwan your post cut off more abruptly than my Fogstar cells in -2°C last January — finish the config spec and we'll crack on, but just know that whatever you're about to say, the answer...
@PanelEwan your sister got "visibility taxed" — supplier spent years under-estimating her usage, smart meter rolled in and went "actually mate, it's worse than you thought"...
Spent three weekends arguing with a multimeter over my van conversion earthing before realising I'd been overthinking it — shed installs are basically the same headache but with more spiders.
Key...
Had this exact faff with my Multiplus last winter in the van — turned out the alarm threshold was set stupidly high in VE.Configure and had nothing to do with actual battery state.
@RetiredSquaddie is absolutely right about that "non-inverting" bit — caught me out on my van build when I wired mine up backwards and spent three days wondering why my Victron MPPT was...
@MarineGeoff nailed the profile thing, but also check your low voltage disconnect in VEConfigure — default is something daft like 10.5V which sounds fine until you realise Fogstar's BMS will...
Been running a Pi Zero W hooked up to my Victron kit via VE.Direct for about two years now and honestly it's been rock solid — once you've got Venus OS Large on there it basically runs itself and...
@Bazza had this exact drama with my cabin setup — grabbed a Victron SmartShunt and trickle-fed the cells back up from around 2.4V per cell using a bench PSU set to painfully low current, basically...
Rewired mine to parallel after my neighbour's new shed started casting a shadow over one panel every afternoon — night and day difference, pun absolutely intended 🌑
Worth noting the Victron 100/30...
@SarahFrost three of those eBay specials on my cabin roof for two years now — the real gotcha nobody mentions is that "100W" is apparently a suggestion rather than a guarantee, so I...
Got my Pi Zero 2W talking to a Victron MPPT via VE.Direct-to-USB, shoves everything into InfluxDB, and Grafana makes it look dead professional — until the Pi itself needs power and you realise...
@EllaDixon71 ran a similar "solar + genny as backup" combo in my van for 18 months and the honest truth is the generator mostly just sat there looking smug until January arrived and...
