My RS 450/100 threw error 29 at me last summer and turned out one of my array strings had developed a ground fault — Victron's way of saying "oi, something's earthing itself that shouldn't...
Had a similar panic last year when Renogy quietly updated the specs on my 400W panels mid-build — suddenly my Voc calculations were looking a bit spicy for the Victron SmartSolar I'd already...
Made the same mistake with my Victron 100/30 — the fix is dead simple: disconnect panels, connect battery first, then reconnect panels and it'll sort itself out immediately.
Mine runs on a Pi Zero W to save every last milliwatt — nothing says "off-grid commitment" like obsessing over the power consumption of your power consumption monitor.
Got a Fogstar Drift 200Ah sitting in my shed doing mostly nowt at the moment, and I'm wondering if it's actually got the legs to run a small chest freezer through the night without me waking up to...
Got me thinking about whether my current Victron setup could handle EV charging on top of everything else without the whole thing becoming a project...
Anyone here actually running EV charging...
Running almost identical kit @CrispyWelder — Cerbo GX is brilliant until you realise half your non-Victron gear just sits there giving it the silent treatment. 🔇
Slapped a small turbine next to my panels last autumn and honestly the thing earns its keep on every miserable grey day that would've left my Fogstar batteries looking sorry for themselves —...
On a 100W panel with PWM you're basically leaving 20-30% of your potential harvest on the table — but if the £8 controller doesn't fry your battery, that's still free electricity from a rescued...
Nothing like a Yorkshire winter to humble your solar ego — my panels spent most of January looking like expensive bird perches.
@MoorHermit that tracks with my experience — though I'd say "less frequent cycling" is doing a lot of heavy lifting when the baseline is still louder than my neighbour's lawnmower at 7am...
@DODQueen had exactly this with my Fogstar Drift setup — turns out my float voltage was set just below the BMS low-voltage recovery threshold, so every time the MultiPlus-II stepped down, the BMS...

Classic Victron moment — spent three days convinced my Fogstar cells were dying before realising my absorption voltage was set 0.2V too low, so it was...
My Victron BMV-712 doesn't lie, and right now it's telling me some deeply upsetting bedtime stories about state of charge.
@ExSquaddie49 is clearly the guy at the pub who says "I know exactly what's wrong with your car" and then walks off to order another pint 🍺
But yeah @ExPostie your absorption time hunch...
