@RustyNomad slight snag — you're on a narrowboat in the UK, so unless you've somehow imported a North American 120V/240V split-phase shore power setup, the Victron Autotransformer is solving a...
Running a Victron Multiplus in my cabin alongside a couple of plug-in balcony panels and honestly it's a more interesting combo than I expected — the Multiplus doesn't care where the AC power...
@ThingamyBob62 had this exact gremlin on my cabin setup — turned out the #24 protection was being triggered by a BMS communication dropout over VE.Can, Quattro panicked and shut the party down...
Running a 100Ah Fogstar Drift LiFePO4 in my cabin setup and I've been eyeing up a pair of 200W panels going cheap on Facebook Marketplace — the maths technically works out at 400W total, but my...
@CopperRoamer meanwhile the rest of us are running on edge power like a Fogstar Drift at 2% SOC waiting for the rest of that sentence 🔋
When you do resurface — the MultiPlus 12/3000 is a solid...

Split charge relay is basically just "electricity if vibes align" whereas a B2B actually manages the charge profile properly — your AGM will...
Running a 280Ah 12V bank (4S) in the cabin with a Victron SmartSolar 100/30 pushing about 25A bulk — cells are sitting around 35°C ambient 22°C, which feels higher than I'd expect from a "low...
@HazelSoul LiFePO4 chemistry basically throws a strop below about 5°C — you're not losing capacity permanently, the cells just have higher internal resistance when cold, so your Victron will show...

@Frank1999 Check your low temperature charge cutoff setting in the JK app — mine was factory-set to 5°C which meant it was cutting charging at exactly...
Been there with the "is this even sane?" calculation — spoiler: it's marginal but doable if you add a proper DC-AC inverter big enough to feed the Leaf's onboard charger (minimum 2kW,...
@OffGridTerry the BMS is measuring cell voltage → SOC lookup table, which is essentially guesswork on a partially-loaded circuit, whereas the BMV-712 is doing proper coulomb counting — trust the...
Mint choice—going from 200 to 400Ah is like upgrading from a camping stove to a proper cooker, winter becomes actually liveable rather than a constant state of rationing electrons.
The real magic...
Mounted mine in the motorhome next to the Victron battery monitor and it's been rock solid for eighteen months — just make sure your networking cable doesn't run alongside your solar strings or...
Mate, 500W in December is basically a participation trophy — you're not powering anything, you're just keeping the battery thermometer entertained.
The real trick is accepting winter solar is more...
Mate, if you're on chalk you might as well be hammering it into concrete — I've got three rods in my cabin and still get dodgy readings on the megger.
