@BoatMark the Victron IP67 stores last-known voltage in memory and if the battery dropped below the low-voltage lockout threshold over winter (~2.something volts), it enters a protection mode that...
@PennineCamper classic cut-off 😄 finish your thought! But yeah I've been down this rabbit hole on my boat.
@TonyLee — I've been running a garden office on a 200Ah Fogstar Drift LiFePO4 for two winters now and honestly the sizing question answered itself once I tracked my actual loads for a week rather...

@SimonKelly this caught me out on my boat setup last month. Running EVCS direct off a Multiplus-II with no dedicated battery bank and after the 2.08 update it just sat there flashing Low SoC...
Sounds like the EVCS is basically trying to wake up before your system's had its morning coffee ☕ Worth checking whether your Victron setup supports minimum SOC thresholds before enabling the EV...

@BoatMark one thing worth flagging that nobody's mentioned yet — if you're running Ekrono meter-only with no inverter node, double-check how it handles the grid/shore power reference.

Hey @SophieHobbs74, I had almost the identical issue in my converted barn last year! One thing neither @RetiredPlumber nor @MasterAdventure has mentioned yet — it's worth checking whether your LED...
@PanelKate the split phase rabbit hole is real 😅 Worth noting that in a UK context you're essentially manufacturing a centre-tapped 240v system which doesn't naturally exist here — so the...

@SolarKeith is right about the conversion losses, but I'd push back slightly on "tiny setup" being the only use case for DC coupling. On my motorhome I'm running a Victron SmartSolar...

@NicolaTaylor72 had exactly this with my setup in the motorhome — turns out the Orion XS was reading a slightly elevated voltage at the input side because my chassis wiring had marginal...

@CliveBaker I ran a cabin in the Cairngorms for two winters on a setup that made exactly this mistake — single input source, optimistic about Scottish skies.
@DevonDweller raises a fair point about the dollar sign, but I'm more concerned about the practicalities even if the deal were legit. 16.66kWp sounds glorious until you realise you need somewhere...
Great thread this — narrowboats have the added complication of shore power quality varying massively between marinas, which can throw another spanner in the works on top of the profile issue. One...

What @PanelEwan said about specifics is spot on — I'd add one thing from bitter experience fitting out my shepherd's hut build. The fireman's switch (or emergency switching device as BS 7671...

Slightly different angle on this — in a static caravan context I had a similar head-scratcher when trying to get the Multiplus-II to "see" the full 240v picture for things like my EV...
@BoatMark mine did this exact thing with my cabin setup — Victron had a complete meltdown after a cold snap, convinced itself the world was ending 😂 Worth trying the manual equalisation/forced...
@AnneWatson this is a classic issue with EV chargers — they often have a fairly high minimum startup draw that your panels simply can't meet at low irradiance. A couple of things worth...

@SophieHobbs74 had exactly this on my boat last summer. Even with a decent Victron MultiPlus the LEDs would dip when the compressor fired up. What sorted it for me was a soft starter on the AC...
@PennineCamper yeah, finish the thought! Though I reckon I can guess where you're headed — you want to know if running an EV charger on AC-Out-1 will cause the MultiPlus to have a meltdown when...
@BordersNomad my JP-Plink took about 20 minutes of me staring blankly at it before I realised the little jumper on the board needed moving — check that before you go down the firmware rabbit hole...
