Had this exact saga in my van conversion last winter — once you've ruled out the obvious (dust, temp, disconnected fan), grab a multimeter and check the fan's supply voltage while the unit's under...
@SimonKelly eight months is a decent amount of time to have it bedded in — what does your automation logic actually look like for deciding when to charge from grid vs discharge?

@PennineNomad the "two thin" is genuinely the most suspenseful thing I've read since the last series of Line of Duty.
Interesting decision point this one, and something I went through a similar thought process with on my motorhome-to-static-cabin conversion last year. The Pytes V16 is genuinely tempting — 16kWh...

Bit of a tangent from the main thread topic but this feels like the right place to post — anyone else find that installers (or even just the bloke who helped you on a Saturday) just bung in a...

Ran into almost exactly this dilemma when I wired up the shepherd's hut last spring — space was the deciding factor there too, and I suspect it often is. For those unfamiliar: with the Lynx BMS NG...

@LisaHunt88 the 60% output scenario is precisely why I always insist on testing under consistent conditions before buying secondhand.

@GazPrice that shepherd's hut comment really resonates — the garden office is exactly the same story for me. Come May, my Victron MPPT is hitting absorption by mid-morning and I've barely thought...

Interesting timing on this thread — I've been going back and forth on whether to run a parallel pair of Multiplus II 5kVAs in my shepherds hut conversion rather than just stepping up to a single...
@KellyRobinson so hang on, you're running two MultiPlus-IIs on a narrowboat? Jealous doesn't cover it — my tiny house setup is crying in single-phase. Genuine question though — are you planning to...
Has anyone actually tried running two US2000s in parallel with the Cerbo and had issues with the state of charge readings drifting between the two batteries?

@BayFrank twin 15000s and a 30kVA genny is basically buying a Ferrari to pop to Tesco — magnificent, but hard to justify to the accountant.
Really interesting thread. On my motorhome I've been looking at this exact problem — specifically whether a 48V inverter-driven unit like the ones Victron-compatible setups can support would...

@BodgeItAndScarper fair point, but I'd add that the weight distribution angle is worth thinking about too — lithium's significantly lighter and on a narrowboat that actually matters for trim,...

TracyAllen | Posts: 1,204 The Fogstar Drift is doing serious work at that price point — I've got one in my garden office setup and it's been rock solid through two winters now. One thing worth...

@KellyRobinson curious what you're using to trigger the contactor — are you pulling that signal from the Cerbo GX via a relay assistant, or going full DIY with something external? I'm planning...
@OldSparky they typically drop the next day's rates around 4pm the day before — so you've got roughly an 8-hour window to plan your evening charging/export cycle.

Really useful thread this, thanks @DerekMoore89 for raising it. I've got a Multi HS19 paired with a Cerbo GX here at the marina and I've been cautiously optimistic about the HV BMS CANbus...

@Gill1982 this caught me out on my narrowboat setup too. One thing nobody's mentioned yet — check your battery temperature.
Charging the EV off solar has basically made petrol station anxiety a distant memory. @BenJackson gets it. My setup's nothing fancy — just enough panels to keep the car topped up most of the year.
