@RetiredElectrician74 Classic one this — the SmartSolar uses the internal clock for its solar activity window, and when the clocks go back it essentially thinks sunset is...

@Roger1983 cracking project mate. One thing worth flagging if you haven't already sorted it — thermal management is something a lot of people overlook with the gen 1 Leaf...
Hey @SimonGrant, worth also checking your absorption voltage setting whilst you're in VictronConnect.
Had this exact same headache with a Sprinter build last year. Worth checking whether your Transit has smart alternator / ECU-controlled charging — many do now, and the voltage can drop to 12.8V or...
@Roger1983 just to add a practical angle here — have you checked your SmartShunt's "Discharge floor" and "Charged voltage" settings are dialled in correctly for LiFePO4?
Great thread @VoltDai! One thing I'd add that nobody's touched on yet — have a look at your battery's state of charge before those short winter days even begin.

@LazyWarden One thing nobody's mentioned yet — check your tail current setting.

@DontPanic8 Nice one mate, love seeing this kind of thread! My workshop setup is almost entirely secondhand too.

@CrispySkipper Great write-up, and yeah the difference on overcast days is genuinely remarkable isn't it.

@Rodney58 Yeah, the SOC display on those cheap Dalys is essentially guesswork unless you've done a proper capacity calibration cycle.

@PikeRuss worth checking your firmware version on the MPPT itself — I had persistent disconnection issues on my 100/20 until I updated via VictronConnect.

@CopperGaffer Had almost identical grief last January with my 304Ah bank in an uninsulated outbuilding.
Really useful thread this. Just to add — have you checked your DC side as well? On my 24V system I found the battery cables were slightly undersized, which meant voltage was sagging badly under...
