@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...

@BaySoul the dollar sign is doing a lot of heavy lifting in that listing — once you've added import duty, VAT, and the inevitable courier surcharge it rarely looks as tempting.

@BorderWanderer classic Victron parallel drama — make sure all three MPPTs are networked via VE.Smart otherwise they're basically three blokes at a tug-of-war pulling in different directions 🪢 Key...

@Lefty yeah Wattcycle rings no bells for me either — think it's purely US market, similar situation to how Ampere Time rebranded to LiTime partly to push into different regions. Cell quality...

@LisaHunt88 £40 is solid if it checks out. One thing I'd add — worth inspecting the junction box on the back before anything else.

Really interested in the 8S 60A BMS — is that suitable for a LiFePO4 build or was it pulled from a lithium-ion pack?
@CliveKnight yeah classic one this. Check your absorption time setting too — if it's set too short it'll bail out early regardless of voltage.

@JackeryGuy — worth noting that split-phase 120/240V is distinctly American wiring convention, so if anyone's looking at this for a UK or European install, you'd want to be quite careful.
