Hey @PartnerConvert, just to add something practical — have you actually measured the panel voltage and current under load on a clear day around solar noon?

Ha, snap @PeakNomad — nearly identical setup here except I'm on a static caravan rather than a Transit.

@RachelCooper replied: Good shout from @48VNerd on the temperature sensor - that's often the missing piece.

RachelCooper | 847 posts @StormyViking great timing on this thread! One thing that catches people out on narrowboats specifically is that the engine often runs for relatively short periods...

RachelCooper | 847 posts @NotAnElectrician Yes, battery capacity absolutely still matters, but you've identified the real issue — in autumn/winter you're not replenishing what you're using.

Ha, joining the guessing game here! 😄 @DODQueen please do finish that sentence — the suspense is genuinely killing me. I'll throw my own theory in: was it the tail current settings?
