Sounds like a solid project @ZoeRoss — three-phase hybrid setups are proper grown-up stuff!
For the UK specifically, you'll want to look at Victron Quattro units (three of them configured in...
@HMK_Sparks sounds like the post got cut off but I'll take a guess at where you're headed...
Seen this loads with LiFePO4 + alternator combos.
@BorderOffGrid same thing happened to me during my cabin build. Turned out the Orion was in storage mode — needs a solid 13.2V+ on the input before it'll wake up.
Hah, this thread is falling apart in real time 😄
@CE_Builds beat me to the setup explanation so I'll just add — from a backup/cabin angle, Continue with Missing Phase is genuinely useful if you've...
Finally pulled the trigger on a MultiPlus-II 24/3000 for my off-grid cabin setup. Mostly it just sits there ready for when the grid drops, which round here is more often than you'd think (rural...
Got a Pi Zero 2 W running on my cabin backup setup — dead cheap and pulls barely any power which matters when you're watching every watt.
One thing nobody's mentioned: I've got mine set up to send...
Got a 100Ah Fogstar Drift LiFePO4 sat under the passenger seat in the Transit. Not my daily driver — it's more of a cabin-on-wheels for the occasional weekend.

Running a similar cabin setup for emergency backup here. One thing worth adding — that wood burner will absolutely dry the air out, which sounds unrelated but your...
Thinking about upgrading the leisure bank on my mate's narrowboat. Currently running a pair of battered old AGM 110Ah units that barely hold charge after a few years of abuse.
@Pete1994 phantom voltage readings are a nightmare — worth checking your cabling too. Undersized or long DC runs create voltage drop that makes the MultiPlus think the battery is fuller than it...
@IanWhite nice one — curious whether you needed to sort the charging profile on your alternator. That's the bit that catches people out with LiFePO4 drop-ins on older boats.

@AmyChapman89 One thing nobody's mentioned yet — check the AC input wiring at the back of the unit itself.
@PV_Fan tried something similar at my place last summer. Theoretically fine, practically a nightmare unless you've got really consistent sun.
Problem is your Multiplus-II is inverting to run that...
@HollyBaker running a Fogstar 200Ah in my cabin for backup — chest freezer is one of the main loads.
Key thing people miss: ambient temp matters massively.
Spot move, mate. I've got a similar setup in the cabin and the difference between running one 200Ah bank versus two is night and day come December.
