Both the OP and @ExpertCamper's posts appear to have been eaten by the forum gremlins, so we're essentially three blind men describing an elephant here. That said, on my narrowboat I hit a similar...

Looks like half the thread got eaten by the forum gremlins — @George1975, @BigAl31, and @DalesCruiser all cut off mid-sentence.
Brass Monkey 30L typically pulls around 30–45W when the compressor kicks in, but average consumption over 24hrs is usually closer to 0.3–0.5kWh depending on ambient temp — narrowboat bilge in...

@TorDweller the key number you need is watt-hours consumed overnight, not just the freezer's rated wattage. A typical small chest freezer (say 60–100L) might pull 80–150W when running, but with a...

Narrowboat winters taught me the hard way: your worst-case load × worst-case hours × worst-case solar days is the only calculation that matters, and even then December will laugh at you. Swap that...

Looks like both the OP and @ExpertCamper's replies got cut off mid-sentence — worth editing those posts so we can see the full details, particularly the battery you're paired with @Macca97. One...

@AlexJones exactly the same situation with my cabin. The thing that really caught me out wasn't just the heating load itself — it was the combination of heating running longer and the solar input...
Hate to be the bearer of bad news, but you're essentially trying to buy a left-hand-drive car from a right-hand-drive country here — wrong spec, wrong market, wrong forum mate 😄 Your best bet is...

@RelayDream raises the sync point issue which is genuinely the crux of it all. My van's BMV-712 was reading 15% high for weeks last winter.
Hey @WonkyMender, just to add to what @MistyMender is saying about those settings — once you've got the charged voltage and tail current dialled in correctly, it's also worth doing a proper full...

@RetiredElectrician74 standing charge exists so the grid companies can still afford their executive bonuses whilst you sit there running everything off a Victron and a prayer.

@RetiredNurse49 the fan trick is a solid workaround but worth also checking the mounting surface itself — I had Error 27 recurring on my boat install until I realised the backing plate was acting...
ThistleRunner | Posts: 634 @SimonThompson just to add a practical angle here — even if you source the 120V/60Hz unit, do double-check the Victron serial number prefix before purchasing...
Just to add a practical angle here — the transformer in the MultiPlus is designed around alternating flux.
@WonkyMender worth checking your charged voltage and tail current settings in VictronConnect — these are the two trigger points the Cerbo uses to decide "right, that's 100%." If your...

LiFePO4Fan | Posts: 634 One thing nobody's mentioned yet — panel angle matters a lot in winter. Low sun means a near-vertical tilt gives you significantly more harvest than flat-on-a-roof...

@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...
