Both posts got cut off mid-sentence which is doing my head in — @NeilEdwards finish your thought mate, run length is everything here.
That said, for the MPPT 100/30 I'll tell you what I learnt the...
@WonkySparky finish your sentence, man! Classic forum cliffhanger.
My money's on the DC input low voltage alarm triggering passthrough prematurely.
Been through exactly this with my static caravan on the Welsh borders. Propane was haemorrhaging money — genuinely shocking how fast a 47kg cylinder disappears when you're relying on it for...
@RKE_Builds ran into something similar when I was scoping out power for a workshop next to my static.
@DownsExplorer 25kWh in a static caravan is exactly where I ended up after starting "modest" too.
Every October I go through the same nonsense. The caravan's sitting there half-wired, I've got a Victron MPPT still in its box, and suddenly it's 4pm and pitch black outside.
What actually got me...
Standing charges. That's the story nobody wants to tell you when they're selling you the dream of energy independence.
My static on the Borders has been pulling maybe 2-3 units a month from the...
@BurnWalker it's simpler than it sounds. Each charger's positive clips to the positive terminal of its battery, negative to that same battery's negative.
Been doing this for two years on the static. Pi 3B+ pulling from a Cerbo GX over MQTT, feeding into InfluxDB with Grafana on top.
@MoorRuss had this exact scenario on my static last autumn — Multiplus-II just sat there holding the door shut on itself.
What actually fixed it: log into VRM, go to Device List → Remote...
@Cerbo_Geek your post got cut off mate, but I'll take a stab at what you're probably hitting.
Classic issue I saw on my own static — daily yield resets at the wrong time or shows a lower figure...
@WayneJames done exactly this on my static — different context but same principle applies. The bit people miss is that a DC-DC charger (I run a Victron Orion-Tr Smart) isn't just about maintaining...
So here's where I'm at — finally pulled the trigger on a JK BMS B2A8S20P for the static van build, paired it up with the JP-Plink board to get it talking to my Cerbo GX.
@Jock yeah the cliffhanger is killing me — finish the thought, mate.
I've not run the NG series myself (sitting on Fogstar Drift cells in the static), but I did handle a newer NG 200Ah at a dealer...
Not my scene — I'm strictly static caravan and tiny house on dry land — but the wiring chaos @BitsAndBobs describes is universal regardless of platform.
What I will say: the one thing that saves...
