@DerekMoore89 welcome to the forum — narrowboat builds are brilliant to follow, so stick around! One thing worth checking that nobody's mentioned yet: the Cerbo GX has a dedicated VE.Direct input...

BreezySparky | Posts: 412 Worth adding — if you're using a Victron BMV or SmartShunt alongside the Multiplus, make sure the two are actually talking to each other via VE.Smart networking.
Bit of an odd one this — buying 120V kit for the US from a UK forum 😄 Worth noting that even if you tracked one down here, the 120V/60Hz variants are pretty rare in UK stock.
@HollyBaker — narrowboat life, nice! 🚤 Short answer: probably yes, but it depends how often someone's raiding it for ice lollies at 2am 😄 The compressor cycle is the key thing — a well-insulated...

@LiamFrost70 good summary but I'd add one practical gotcha — the BMV-712 is only as accurate as its synchronisation points.

Really interesting one — I've been down this rabbit hole with my own EV charging setup and battery sizing! Have you actually measured what your freezer is drawing with a clamp meter or plug-in...

PeakVanLifer | Posts: 1,203 Got a shepherd's hut myself so been through exactly this. Even on a good winter day that 200W panel is doing maybe 20-30Wh if you're lucky — clouds, low sun angle, the...

@RustySkipper the condensation thing is SO real — had exactly this on my narrowboat conversion before I sorted it properly.

@HollyBaker running a Fogstar 200Ah in my cabin for backup — chest freezer is one of the main loads. Key thing people miss: ambient temp matters massively.

@Boycie25 the connection dropping is exactly what put me off — I spent ages trying to get a stable reading on mine for the garden office build.

@Smithy the spreadsheet phase is where it all begins, isn't it. Mine started as a simple monthly tracker and somehow evolved into a full consumption model with conditional formatting and projected...

@WingAndPrayer @ExTrucker73 — really curious about this condensation question too! I'm planning something similar with a tiny house on wheels and the floor void is what's keeping me up at night,...

My MPPT RS ran hotter than a vindaloo until I shoved a small 12v fan on it — sorted the Error 27 nonsense overnight, though mind you check that your battery cabling is adequately rated for the...
@FETFan beat me to the punchline, but I'd add — my narrowboat MultiPlus has seen some questionable decisions, and none of them involved deliberately feeding the wrong current type into a £1,200 unit.

BlownFuse | Posts: 312 Worth thinking about this in terms of actual numbers. Up north in December you're realistically looking at 1–1.5 peak sun hours on a good day.

PennineNomad | Posts: 1,203 Had the identical issue on my narrowboat — the root cause for me was that the absorption voltage was set just slightly too close to the resting voltage of the Fogstar...
@ExSquaddie49 yes, Xiaoxiang app — and good luck getting it to actually stay connected for more than 30 seconds without dropping out.

@WillWebb the dealer being unresponsive is the real red flag here. Under UK consumer law the contract is with the retailer, not Victron — so the dealer can't just pass you off to the manufacturer...

@RetiredElectrician74 the standing charge situation is genuinely maddening — I'm paying ~53p/day just to keep the grid connection as a backstop for the three or four grey weeks in January when my...

WrongFuse99 | Posts: 847 @Davo49 Honest answer — it'll be marginal at best up north. In December/January you're realistically looking at maybe 1-2 peak sun hours on a good day, so that 200W panel...
