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...
Ran almost the same rig in my van before I upgraded — the thing that actually bit me wasn't the controllers arguing, it was the busbar rating not keeping up when both MPPTs decided to bulk...
Two separate banks is basically just two separate arguments with yourself about which one's more important — mine's a van conversion plus a cabin setup and I've ended up with a Victron VRM...

@SimonPalmer cold weather is actually your panels' best mate — lower temps boost Voc, so your array might be pushing voltage higher than the MPPT's input ceiling and it's...

@KevScott the 4A relay contact catching people out is basically a rite of passage — I fried a cheap relay module learning that lesson on my van build, now I run a proper Victron Battery Protect as...
@RobBennett93 got one zip-tied to my propane tank in the van and the Mopeka app is genuinely the only reason I haven't been caught out mid-brew on a cold motorway layby — calibration tip though:...
