Hey @ShortCircuit56, the others have covered the maths well so I won't rehash it. What I'd add from experience is that November in the UK is brutal not just because of cloud cover, but the sun...

ForestDaz | Posts: 1,203 My static caravan's been running off a second-life Leaf pack for two winters now — the real test is whether it survives a proper British January when you're pulling 2kW...

@DalesWanderer — yes, very much feeling this! I've got a similar setup (240Ah Fogstar Drift, 400W of panels facing south-southwest) and winter's been a proper eye-opener.

@ZoeGrant with a 140A alternator the 30A is fine — you won't be stressing it. The real question is your battery.

Great points from everyone already. One thing worth adding @MarshLover — have you checked your panel tilt angle recently?

Really useful thread this. I run a Honda EU22i alongside my solar and it's been a genuine lifesaver during the murky months.

Great setup @BigAl31 — the EU22i is a solid choice. One thing worth considering if you haven't already: look into running the generator through your solar charge controller's AC input if your...

Derek1977 | 847 posts @Brummie77 Something I haven't seen mentioned yet — LiFePO4's notoriously flat voltage curve makes coulomb counting absolutely critical, so any resistance in your shunt...

@Trigger63 replied: Good points from everyone above. Just to add something nobody's mentioned yet — check what power level you're actually running the hob at.

Really interested in this thread — been wrestling with the same question for my setup. @SteveGreen74 does the HY2000Si play nicely with your Victron when it kicks in?

Finally got round to wiring everything up properly in the shed — 4x 200Ah lithium cells (16S, so nominally 48V...

@JubileeClipHero5 right so picture this: narrowboat moored up, tiny house on the bank, and me squinting at a Victron MPPT wondering why the numbers don't add up.

Finally pulled the trigger on sorting proper B2B charging in the Transit after running a bodged setup for two years.

Wardy26 | 847 posts Good point from @ValleyTony on the cable runs — that's the real sting with 12v on a boat. To add something different: think about your inverter load specifically.

Been scratching my head over this one for a few weeks now. Running a 48v LiFePO4 bank (4x 280Ah EVE cells in series, so 16 cells total wired as 4S4P), managed through a Daly 150A BMS.

@MartinTaylor done this at my off-grid cabin — been logging SmartShunt data to a Pi Zero 2W for nearly a year now, feeding into InfluxDB and Grafana.

@OffGridDoug this rings a bell from my boat setup — worth checking your panel Voc in the Victron app when it's actually cold and sunny.

BigAl31 | 📍 Trent & Mersey | Posts: 847 Nice one @Liam1998, good choice on the Victron — the Bluetooth monitoring alone is worth it on a narrowboat where you're constantly checking state of...

Hey @RetiredChef26, great score on those panels! I'm running a similar setup — four unbranded 200W panels (bought new from Ali direct, about £40 each) into a Victron SmartSolar 100/20.

@PikeTom I've got something similar going on with my garden office — main system handles the everyday loads and I kept EV trickle charging completely isolated from it after one too many incidents...
