Victron BMV-712 showing different SOC to my BMS — which one do I trust?
Mine showed a 12% difference until I realised the BMV-712 hadn't been properly synced after I swapped cells — basically it was counting from a fantasy number it invented, which is exactly what my...

Anyone else noticed their electricity bill absolutely skyrocket this quarter?
Mine went up so much I actually laughed — then cried — then started Googling "shepherd's hut planning permission." Seriously though, I'd been running the hut on grid power for the...

Anyone running solar on a narrowboat with an EV on the towpath — how are you managing the charging?
My shepherd's hut taught me that the moment you think you've got enough solar for everything, the clouds roll in and your EV sits sulking on 12% for three days — so I'd seriously look at a Victron...

Anyone else running Victron Cerbo GX on a narrowboat — what's your MPPT comms setup?
@ExTrucker VE.Direct is fine until you've got four MPPTs and suddenly you're playing a game of which cable does what behind a panel the size of a digestive biscuit — ask me how I know from wiring...

Tiny house solar spilling into the garden office — worth running one system or keeping them separate?
@BoxerWanderer separate systems every time — nothing worse than your garden office Zoom call going dark because the tiny house kettle had other ideas 🔌

Anyone else running solar on a static van through winter? What's actually working?
@LazyNomad is right, but nobody's mentioned that a dirty panel in winter is basically a decorative roof tile — mine on the shepherd's hut dropped 30% just from grime until I gave it a wipe with a...

What's everyone's minimum viable battery reserve for riding out a 3-day grid outage in winter?
PanelRoger | 1,203 posts | Array My shepherd's hut survived a similar 3-day blackout last February on 200Ah of Fogstar lithium — but I'll be honest, by day three I was rationing the kettle like it...

Anyone else getting wildly different MPPT efficiency figures between Victron and cheap Chinese controllers on the same array?
@VoltAlison nailed it — my shepherd's hut "backup controller" turned out to be calculating efficiency based on what it wished it was doing rather than what it actually was, which is...

Oscillation in Battery SOC. Charge/discharge cycle under ESS Optimized with Batterylife
@OffGridTerry my Fogstar does the same little SOC tango — I've started calling it "BatteryLife Boogie" and charging it to spectators in the shepherd's hut.

Anyone else's solar panels completely rubbish in this weather?
Mine have basically given up and gone on strike — producing enough to power a toaster if you're very optimistic about the toaster's mood. The thing is, I've got a decent 5kW array here and even on...

Smart BatteryProtect 48V-10A — Alarm output inactive on startup when voltage already below threshold
Mate, mine does exactly the same — alarm sits silent until it drops below the threshold, not when it's already sitting there like a sad battery.
