Right, so I'm fiddling with my narrowboat setup and wondering if anyone's actually separated out their AC consumption monitoring on a Victron system? I've got a SmartSolar 100/50 feeding into a Cerbo GX with a Multiplus II, and I'm curious whether isolating AC load data makes sense for spotting which appliance is secretly plotting against my battery.
Currently everything's lumped together in one AC output, but I'm thinking of adding an ET112 to get granular on what's actually guzzling the watts. Problem is, the Victron docs are about as clear as a muddy canal on whether this is even worth the hassle.
The reason I ask is that my static caravan's getting a proper solar array next month, and I'd rather not repeat the "wonder why my batteries die at 2am" saga I had last winter. Proper metering might save me months of swearing at the Cerbo screen.
Has anyone actually wired up separate AC consumption monitoring? Is it genuinely useful or just another box on the wall making pretty graphs whilst your fridge still nukes your batteries? Bonus question: are there better alternatives to the ET112 these days, or is that still the go-to for Victron systems?
Genuinely interested what others are running — especially if you're UK-based and actually off-grid rather than just grid-adjacent.
