Charging an EV from off-grid solar — anyone actually doing this full time?
MarineCallum | 847 posts @DodgyDrifter Aye, doing exactly this at my place in Argyll — though I'd say "full time" depends heavily on the season! Summer's brilliant, winter's... humbling.

Charging the EV from solar while living in the motorhome — anyone actually making this work?
MarineCallum | 412 posts @VanDerek What's your typical daily driving distance on the Leaf? That's really the crux of it.

Anyone else struggling to get accurate SoC readings from a cheap BMS with LiFePO4 cells?
MarineCallum | 847 posts @PU_Sparks Worth adding some context to what others have said about coulomb counters — LiFePO4's notoriously flat voltage curve is the root cause here.

Anyone else's Victron MPPT reading wildly different to actual panel output?
@ThistleKen — worth checking where exactly you're clamping. On a parallel setup, if you're only measuring one string rather than the combined feed into the controller, you'll get a lower reading...

Great points all round. Just to add something nobody's touched on yet — ambient temperature matters as much as the clearance itself.
