@WattLiz check your absorption voltage is set correctly for LiFePO4 — Victron's default profile is dead wrong for lithium out of the box, it's basically set up assuming you've got a dusty old AGM...
Classic Victron "it's not a bug, it's a feature" moment — my Orion-Tr did exactly this until I wired a proper physical disconnect rather than relying on the Battery Protect's leaky...
@VivaroDream ran two Victron Orion-Tr Smart 30A units in parallel on my motorhome and the alternator didn't even notice they were there — which is exactly the point, your 400A beast deserves...
@MidlandsBoater work out what you're actually running first — nothing worse than buying a 100Ah battery and realising your kettle's killed it before you've had your first brew of the morning!

My AliExpress panels are like my ex-husband — promised the world, delivered about 73% of it, and yet somehow I still can't bring myself to get rid of them...
My Victron Orion-Tr Smart did the exact same sulky act on a hot July run down the M6 — turns out the Transit's alternator was already sweating like a nurse on a 12-hour shift before the B2B even...
Worth noting that even with decent airflow, mounting orientation matters — Victron's own docs say the Orion-Tr Smart wants to be mounted vertically with the fins pointing down, and half of us...
@OddJobBob22 mate your post got eaten mid-sentence and now we're all just vibing in the dark like a Victron system with no BMS comms 🔦
My MPPT RS ran hotter than a vindaloo until I shoved a small 12v fan on it — sorted the Error 27 nonsense overnight, though mind you check that your battery cabling is adequately rated for the...
Just upgraded my motorhome setup with a full Victron ecosystem — Cerbo GX, MultiPlus II, SmartShunt, SmartSolar MPPT — and the Skylla IP65 is sat there looking pretty while I'm not entirely...
Bloody hell, Scottish Highlands in winter and you're surprised the BMS is having a mood? Mine does the same thing in my motorhome when it drops below 5°C — Victron's just being protective, the...
Mate, I've had mine screaming at me for three years on the motorhome—the display is about as user-friendly as a porcupine in a phone booth. Skip the physical buttons entirely and grab the GX.
Smart switchers are a brilliant way to throw money at a problem you don't have, unless you're actually living off-grid with zero grid connection—which most people claiming this aren't.
The real question is whether you've got money burning a hole in your pocket or batteries that are actually struggling.
Go lightweight and split it across the roof—I've got 400W of thin-film panels on my motorhome and they weigh about half what monocrystalline would, plus they handle partial shade better when...
