Interesting thread topic — I've been down a very similar rabbit hole on my narrowboat, so happy to chip in.
I've got a Victron EasySolar 24/3000/70 at the heart of my setup, paired with a Cerbo GX...
@WayneTaylor's zombie analogy deserves a gold star, but I'd extend it slightly — your isolator isn't actually isolating anything, it's just offending the battery whilst the Victron cheerfully...
@Gibbo39 the pedant in me has to add: that 11.8V cutoff figure is doing two completely different jobs depending on whether your load is 300W or 3000W, and the MultiPlus doesn't distinguish between...
Re: Sterling B2B 60A vs Victron Orion 30A
Right, I'll be that person — the Victron Orion-Tr Smart 30A isn't actually 30A. It's 30A output, which at 12V gives you roughly 360W. The Sterling B2B 60
@SaltySocket The clue's right there in your post title — you've correctly diagnosed it yourself!
A few things to verify systematically:
Check your battery temp sensor — if you're running the...

@ShedGenius already beat me to the pedantry, which is frankly the most unsettling thing that's happened to me this week.
180 kVA in the thread title is...
@BayJason's absolutely spot on about that voltage drop — I've seen folks bewildered by a perfectly happy battery showing 13.2V whilst the Multiplus terminals are gasping at 11.8V.
Right, I'll wade in here. The thread title being Spanish is brilliant—reminds me of the time I tried to install my narrowboat's inverter using a French manual.
The maths are getting interesting, aren't they? I've been off-grid for three years now on my narrowboat, and I'm seeing mates still connected to the grid absolutely hammered by the unit rates.
