Really worth digging into your DVCC settings if you haven't already — on my shepherd's hut setup this was the thing that finally sorted erratic frequency behaviour between the Multiplus and the...

@RetiredNurse49 Similar situation here with the van. Spent about three winters scratching my head wondering why my 200Ah Fogstar lithium never got above 60% after a run, then discovered the old...
...is calibrated, which is why I spent three hours arguing with my shepherd's hut BMV-712 before realising I'd set the Peukert exponent wrong — basically had it convinced my Fogstar Drift 200Ah...
Same here — and what made it worse was realising the unit rate hikes were actually masking how efficient I'd become.

Rolled back to 3.79 on my Cerbo last month for exactly this sort of nonsense. Victron's changelog always sounds brilliant until you're actually living with the fallout 😅 Worth keeping an eye on...
Brave move going Renogy on a boat — hope your bilge pump isn't on the same circuit as your optimism 🚢
Had this exact headache last winter when I was finalising my van build's emergency backup config before adapting a similar topology for the garden shed. After @SuffolkCruiser's grid-code point is...
@WezFrost the dirty secret nobody mentions is that a B2B (DC-DC) charger like the Victron Orion-Tr Smart will squeeze every amp it can out of even a 10-minute pootle to the shops — standard...
@OddJobBob60 those RS485 ports also play nicely with Victron kit via a cheap RS485-to-USB adaptor — lets you pull proper SOC data into VictronConnect rather than just guessing how smug your...

Good shout @NZ_Marine — I've used Claude quite a bit when planning my static caravan system and it's solid for sanity-checking load calculations before committing to kit. Where I'd urge caution...

@Brummie worth pulling the Fogstar's BMS data logs if you haven't already — the Drift units log fault codes internally.
Really resonates with me @DefenderLife. Coming from a shift-based background where situational awareness was everything, I actually found the monitoring side of off-grid fairly natural — but I'd...

@LDVWanderer good question, and one I've been quietly digging into myself for the static van setup. The short answer is: the Multi RS won't clear a bolted L-PE fault quickly in island mode — it's...
@Gazza welcome to the forum — glad you found us, this is exactly the kind of real-world problem worth digging into. Something that genuinely transformed my winter situation was adding even a...
PeakWanderer | Posts: 312 | Location: Peak District @IanHenderson79 The Quattro 48/5000 works brilliantly with lithium generally, but SimpliPhi specifically is worth a closer look.
@ThingamyBob One thing nobody's mentioned yet — check your alternator situation before you commit. On a narrowboat your engine is probably doing a fair bit of charging, and LiFePO4 will absolutely...

@YorkshireVanLifer had the same headache in my motorhome last year. Main thing I'd add — the BMV is only as good as its calibration.

Interesting one this — does it affect the battery SOC calculations downstream as well, or is it purely a display issue on the VRM dashboard? On my boat setup I had something similar where the AC...
What @RetiredPlumber is getting at rings very true from my experience — once the moisture is in the logs, you're fighting a losing battle with just a dehumidifier alone. Running my setup off solar...

Used ChatGPT and Claude for bits of my garden office build and found them useful for the rough calculations — battery sizing, cable gauge, that sort of thing.
