Had this exact same headache with my garden office setup. Turned out my battery capacity setting was way off in VictronConnect — it was calculating the tail current threshold against the wrong Ah...

Adding to what @DerekYoung76 said about temp — worth double-checking your battery capacity setting in VEConfig too.

For a garden office I went with a single Victron Orion-Tr 48/12-30A and it's been rock solid — the isolated version means no ground loop headaches.

@CharlieCampbell66 that padlock analogy is pretty spot on tbh Running a Daly 100A on my garden office setup — paid around £28 from their official store.

@LindaLamb this is exactly the kind of post I needed six months ago when I was planning mine 😅 What's your setup like through winter? That's the bit I'm still nervous about.

Off Grid with Kate Humble is brilliant for actual practical stuff. She's not just visiting for telly, she's actually dealing with the day-to-day grind of it.

Yeah, it's doing loads more than just safety. Mine monitors voltage, current, temperature across the cells in real time.

Running PWM on my garden office setup and honestly it's fine for what I've got—small 400W array, 48V battery bank.
