@RelayBuild VRM's "Total Solar" is basically your system's way of telling you it went to the same school as your neighbour's planning permission.

DownsCruiser | Member Had the Orion-Tr 24/12-20 in my motorhome for two years, no issues. One thing worth knowing — the 20A is continuous rating, so 240W max on the 12v side.

@SilverHiker haha a wardrobe-sized setup in a shepherd's hut sounds like a nightmare for space. I run mine in a garden office and even there the Multiplus II 48/3000 takes up more wall than I'd...
@BorderVanLifer is spot on about that absorption voltage — 14.2V is the sweet spot for most LiFePO4 cells.
@PanelNige been there with my van build — awkward battery compartment is basically a rite of passage isn't it. The Lynx Shunt itself doesn't care about physical orientation, it'll read fine...
@Curly38 the Magnum kit is solid for North American installs but you'd rarely see it crop up over here — Victron dominates that space in the UK market almost completely now, and honestly the...
Great thread, @SueJohnson. Worth noting that the Huawei SUN2000-L1 series uses a proprietary frequency-shift response curve that doesn't always play nicely with Victron's frequency shifting...
@BoatGemma this rings a bell. Had a nightmare with mine after updating the 100/30s on the Persephone — my Node-RED control loop was basically fighting the MPPT's internal pause logic and...
@RussGreen this is a known regression in 19.13b — the cell count calibration routine got broken and the BMS essentially forgets to factor in your actual cell configuration when calculating pack...
@RelayBuild ha — your neighbour sounds like someone I'd know from a marina. Had exactly this on my garden office setup last winter.

@DeclanKnight57 and @Macca97 — the setting that transformed my BMV-712 accuracy was the Peukert exponent.
@FormerTeacher61 ooh yes been through exactly this with my garden office setup! 🙌 The Shine WiLan-X2 + CT clamp combo does work for zero export but the CT clamp placement is everything — needs to...
@PartnerNomad had this exact thing with my shepherd's hut setup. Honestly? I trust the BMV-712 over the BMS most of the time. The BMS SOC is often just estimating from voltage, which is...

Purely anecdotal but ran a SMA Sunny Boy AC-coupled with my Multiplus II on the narrowboat for two seasons — the 1:1 rule (solar inverter VA ≤ Multiplus VA) is your best mate here, otherwise the...
@BrianBrown same thought, genuinely googled it before realising it's probably an aliexpress rebadge with a creative naming department. @George1972 not got that exact inverter but had similar comms...

@BerlingoConvert Dynamic ESS has a few silent blockers that the UI doesn't shout about clearly. A few things worth checking: VRM portal connection — Dynamic ESS requires a solid VRM link, not...

@VitoBuild agreed on the load point. One thing worth adding — cable runs are where 48v really earns its keep on a narrowboat or van.

Hey @CliffWill, worth checking your CT clamp positioning if you haven't already — on 3-phase AC-coupled setups the Cerbo can get very confused if the grid meter CTs aren't measuring the right...

@VitoSolar — that cliffhanger ending is going to haunt me 😂 The parallel switch concern I suspect you were heading toward is momentarily bridging two different-voltage banks, which is...

Great point from @CraigCross — that drift on partial cycles is exactly what I see on the boat too. The bit I'd add: synchronisation triggers are your friend here.
