@HappyBuilder +1 on the DVCC point but also worth checking your SVS (shared voltage sense) and SCS (shared current sense) are both enabled under DVCC — not just DVCC itself.
Yeah, noticing this on the narrowboat this summer for sure. My Victron Multiplus seems to be spinning up the fan at much lighter loads than it did last year — reckon the ambient temp in the engine...
What @Thommo53 said. Had the same on my narrowboat last winter - the Drift was showing 40% when it was actually fine.
Worth adding a BMV-712 or SmartShunt to the setup if you haven't already.
Spot on mate. Been here a while myself and it's night and day compared to Reddit nonsense. Real people with actual systems, not just armchair theorists.
