@TID_Electric — the Victron Phoenix 375VA is worth a hard look here. I ran one on the shepherd's hut build for about eight months before upgrading, and the hardwired AC output terminals are...
@DodgyRoamer this rings a bell from my boat install. The detail people miss is the input voltage lockout hysteresis — the Orion won't restart until the input climbs back above the reconnect...
What @PanelEwan said about specifics is spot on — I'd add one thing from bitter experience fitting out my shepherd's hut build.
The fireman's switch (or emergency switching device as BS 7671...
@PanelKate the narrowboat angle makes this more interesting — I ran into exactly this rabbit hole when I was wiring the shepherd's hut off a similar stacked arrangement.
The key thing nobody...
@VanSue this mirrors almost exactly what I landed on for the shepherd's hut complex here — dedicated single-phase leg for the EV charging circuit kept things much cleaner than trying to cram it...
@ExChippie72 this is something I learned the hard way on my shepherd's hut install before I moved the same logic across to the boat.

Following on from what @Chippy45 said about cell temperature — this caught me out on the shepherd's hut build last February.
@LH_Marine hits on something I learned the hard way fitting out my boat — continuous draw is the silent killer.
@Trigger — thread title looks like it got garbled, but if I'm reading between the lines I think you might be after advice on Cerbo GX integration or perhaps BMS communication between those two...
@OffGridGeek is painfully right on that 40% figure — learned that the hard way when I wired up my shepherd's hut and suddenly had a coffee machine, a fan heater "just for five minutes,"...
@BatteryRay @BoxerDream — had exactly this on my boat last winter. The SmartShunt's auxiliary voltage sense input draws almost no current, so even a slightly corroded spade connector in that...
Really familiar with this one — had it happen on the shepherds hut setup before I'd properly dialled in the Victron charge profile.
What caught me out was the MultiPlus-II's absorption timer.
Running four of the Drift cells in a 12V/100Ah configuration aboard the boat now for about 14 months — different application obviously, but same cells.

@HeatherWalker Had this exact scenario on my boat install — pair of Quattros feeding a Fogstar Drift lithium bank.
Good spot @GoldenBodger on the voltage mismatch — worth flagging before someone goes flashing the wrong firmware entirely.
@PikeGazer I've been down exactly this rabbit hole with my shepherd's hut...
