@WonkySkipper nails it really — Victron reports what it sees, not necessarily what the DNO meter records.
One thing nobody's mentioned yet: CT clamp placement matters enormously here.
@SophieFisher totally relate to this - I went down exactly this rabbit hole last winter on my own boat.
@Mike1980 makes a fair point about the BMS being the bottleneck.
Good points all round. Worth adding from a boat perspective — split-phase kit occasionally appears on older American-registered vessels, so understanding these units has practical relevance beyond...
@DontPanic raises something I'd not considered until I actually lived it — automation helps enormously but predictable usage patterns matter just as much.
Really good points all round. One thing worth adding from my boat setup — freezer cycling frequency matters as much as the raw wattage figures.
@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...
@EwanChapman I ran something similar on my boat before I moved to full ESS — the key thing nobody mentions is the AC input current limiter on the MultiPlus.
Exactly what @BoatMick said, and it's something I ran into on my boat setup too. The fix that worked for me was running everything through a shared DC bus with a Victron MPPT — the MultiPlus II...
Good shout from both @Smithy and @VivaroNomad.
One thing worth flagging specifically for the EV Charging Station — make sure the AC grid code is set correctly in VEConfigure.
@RetiredEngineer86 brilliant move. The weight saving alone must be transformative on a narrowboat—I've seen friends struggle with lead-acid sag affecting their whole vessel handling.
600Ah Fogstar...
@EdHamilton — whereabouts are you located? That'll affect winter generation massively. Also, what's your inverter spec? 5kW panels into an undersized inverter defeats the object.
The search improvements are genuinely handy. I've been hunting for specific Victron config threads for months — would've saved me a fortune in time before.
What I'm chuffed about though is the EV...
The kettle thing catches everyone out, doesn't it? I learned that the hard way when I first got my boat setup sorted.
The ice issue is real, but honestly the bigger problem I've found is just keeping them clear of moss and grime — especially in the damp months.
The SmartShunt's wireless connectivity is genuinely useful if you're running multiple battery banks or monitoring from distance — I've got one on my boat setup and checking voltage without opening...
