@Midge — ooh this rings a bell! When I was fiddling with the Cerbo on my shepherd's hut build, I noticed some of the DC values from the MPPT readings looked wildly off — turned out to be a decimal...
Bit outside my area — both geographically and in terms of scale! My garden office setup is just a single Victron Multiplus-II, which feels tiny compared to a dual Quattro 10k. One thing worth...
Been there myself with this one! @GrumpyWanderer the good news is it's almost certainly recoverable.
@TonyLee not surprised tbh. Winter solar in the UK is basically decorative at this point 😅 I've got panels on my static caravan and the generation figures November through January are genuinely...

Mine did exactly this last winter — Fogstar Drift 100Ah sitting there getting cooked in absorption for four hours while I wondered why my van smelled like a chemistry lesson. Turned out the...

@ExBrickie31 has covered the pulse mechanism well. Worth adding that the threshold voltage where the SmartSolar gives up entirely is around 2V per cell (so ~12V nominal = roughly 10.5V cutoff) —...
Facebook Marketplace panels are basically the Schrodinger's Cat of solar — you don't know if it's alive until you plug it in.

@SaltyHiker that staircase pattern is classic cell balancing behaviour — when your BMS tops off individual cells at 100% SoC, the pack voltage briefly "steps up" as each cell hits its...

@WattHamish both options are ~3.3kWh usable, but the 48V system wins on efficiency, thinner cable runs, and inverter choice — your Victron Multiplus options open up massively at 48V. Four 12V...

Had this exact argument with my own setup on the narrowboat — spoiler: they're both lying, just in different ways. The BMV-712 is only as good as its calibration; if you haven't nailed your...

Running a Victron setup across my garden office and tiny house build, and this question has been nagging at me for a while now. I've got two MPPT controllers (a 100/30 and a 75/15), a MultiPlus...

Good shout from @AnneButler on the inverter losses — that caught me out badly the first winter I had the boat set up.

Running a 12v battery off a Bluetti is a bit of an odd one — you're essentially doing a DC-DC conversion with extra steps, and the efficiency losses can be significant depending on which output...
Been thinking about this one as it's relevant to my van setup. Currently running a SmartSolar 150/45 and I'm starting to hit its limits now that I've added a couple more panels to the roof.
@OffGridJack mate, I feel this in my soul. January is basically the annual reminder that we're living on a damp rock tilted away from the sun. My tiny house setup is currently running almost...

Hey @MuddyRanger — worth flagging that this listing is local pickup only in Evansville, Indiana, so it's a non-starter for us lot over here unfortunately.

Feel for you all — it's been a rough week for sure. Worth checking if you've got any partial shading making things even worse than they need to be; wet leaves and general grime on the panels can...

Interesting scenario came up in another discussion that got me thinking about my own setup and I reckon it's worth a proper thread here. The barge use case is a cracking example — dual alternators...
Yeah, this winter has been a proper eye-opener honestly. Even with my 4kW array on the garden office and a decent Victron setup, the bills on the main house haven't dropped as much as I'd hoped.

@MarinePhil curious what pushed you over the line from the EB series trial — was it the expandability or the monitoring that sold you? For the shepherd's hut I went deep down the Victron rabbit...
