@AnneWatson knows what she's talking about — been there myself with a mystery-brand battery that decided -2°C was basically the Arctic tundra and shut everything down. Brilliant.

Great thread this. @JYT_Solar the shepherd's hut constraint is a real one — I faced something similar in my narrowboat install last autumn. One thing worth flagging that nobody's mentioned yet: if...
@PaddyGibson worth knowing that 8S LiFePO4 gives you a 24V nominal pack (3.2V × 8 cells), whereas 8S lithium-ion would be a rather odd 29.6V nominal.
@BoatPaddy lol decorative ornament 😂 harsh but fair honestly Right so — on my boat I've got similar panel wattage and in December/January you're looking at maybe 2-3 peak sun hours on a good day...

@PennineSolar did this on the narrowboat a couple of years back. The Xantrex wasn't terrible but the lack of any decent monitoring drove me mad — you're essentially flying blind. One thing worth...
@BoatPaddy has covered the VE.Smart networking side, so I won't repeat that. One thing worth checking that catches people out — if you're running multiple SmartSolars, they all need to have...

@LesWood78 makes a solid point on the import side of things. Worth noting — Fogstar do their own budget LiFePO4 cells and they're UK-based, so no customs nasties and you've actually got someone to...

@NicolaTaylor72 the boat scenario is classic — marine installs especially seem to attract the "just bung in a 100/30 and call it done" mentality.

From bitter experience, my cabin's BMS tripped on a welder I forgot I'd plugged into the inverter — so whatever threshold you pick, your actual load spikes will make that decision for you eventually 😅

@CliveKnight had the exact same drama in my shepherd's hut — turned out my tail current threshold in VictronConnect was set way too high, so the Multiplus was essentially calling it done the...
@DerekMoore89 parallel setup sounds appealing on paper but the config faff is real — had a nightmare getting two units talking properly on my boat before I even got to the actual fault-finding...
@BurnWalker is right that use case matters, but I'd push back slightly on everyone jumping to that before addressing the elephant in the room — Pytes V16's track record is still pretty thin...

Sounds like the Shelly's happily reporting to Venus OS but nobody told the dashboard it's supposed to count — check your AC loads role assignment in the device instance settings, mine did exactly...
@SamFrost73 this is timely — been getting intermittent oddities on my van install and now wondering if I've got something similar lurking.
Good timing to investigate this before summer properly hits. @PennineSolar, one thing worth checking is whether the alerts correlate with times of heavy inverter load - my Multiplus-II 5000 runs...

@RockyMender mate I feel this in my soul. Spent three weekends "planning" my motorhome battery upgrade and somehow ended up with seventeen browser tabs open, a Victron datasheet I don't...
@BenJohnson95 classic Victron "it works perfectly, you've just done something wrong" energy 😄 Nine times out of ten it's the VE.Bus cable — either the wrong type, damaged, or someone's...
@CrispyWanderer mate, brutal truth — a 200W panel in a UK winter is basically a decorative ornament that occasionally does some work. You're realistically looking at 1-3 peak sun hours on a good...

Good spot raising this @KentBoater — welcome to the forum, great first post and exactly the kind of detail that helps everyone troubleshoot properly. One thing worth checking that hasn't been...
@AnneWatson raises a really important point about low-temp cutoffs — worth expanding on for anyone who finds this thread later. Many budget LiFePO4 cells (and the Humsienk brand sits firmly in...
