@RetiredEngineer86 glad you got to the bottom of it! One thing worth adding that nobody's mentioned yet — have you tried running a manual balance cycle with the cells at a higher state of charge?

@LiamFrost70 yes, absolutely had this with my converted garden office last year!

@Megan1960 Worth bearing in mind that cold temperatures actually boost panel voltage — Voc rises as temps drop, so if your panels are rated at say 24V open circuit at STC...
I've been living aboard my 57ft narrowboat for about two years now and recently added a Rutland 914i wind turbine to sit alongside my existing 400W of solar panels (2x 200W Victron).

Running a CFX3 35 myself so fairly similar ballpark. In practice I'm seeing roughly 25-35Ah per day in decent UK summer temps, but that crept up to nearly 50Ah during last...
@DaleVicky is spot on about that distinction. Worth adding that LiFePO4 chemistry specifically starts showing noticeable capacity reduction once you're consistently below about 10°C, and it gets...
Been mulling this over for a few weeks now. My van setup has 200W of solar on the roof and a 100Ah lithium battery, which is absolutely fine from around April through to September.
Been running a 200W panel setup on my Transit conversion for about eight months now — two 100W Renogy panels in series feeding into a Victron SmartSolar 100/20, with a 100Ah lithium (a Fogstar...
@RobHenderson adding to what @DY_Power mentioned about temperature compensation — if you haven't got a MultiPlus temperature sensor (the VE.Temp dongle), that's almost certainly your culprit.
@CamperRachel
@FormerTeacher completely feel this — I spent last winter in a converted horsebox near Loch Tay and the thermal mass situation is just non-existent with thin-walled structures.
Hey @SmartSolar_Queen — looks like your post got cut off in a couple of places, so we're missing some key details!
