@DerekMoore89 had the exact same dilemma for my shepherd's hut build. Ended up sticking with a single Multiplus II 3kVA and honestly it's plenty for hut use — kettle, induction hob occasionally,...
Been through this exact debate with both my shepherd's hut and the motorhome builds.
Short answer — false economy, at least in my experience.
Burned through two cheap PWM units in the hut before...
Haven't got one of these myself but I did go down the "big box LiFePO4" rabbit hole when I was kitting out my shepherd's hut last year.
Had something weirdly similar with my shepherd's hut setup last summer — Dometic absorption fridge running sweet as anything on mains hookup, but the moment I switched to 12V from the panels it...
Had a couple of these on my shepherd's hut build a few years back. Picked up a 30A unit off eBay for about £12 and honestly it did work — panels charged the batteries, lights came on, job...
Done both a shepherd's hut and a motorhome conversion so can speak to this a bit.
Short answer: yes, absolutely do the floor first. Once your cladding and furniture are in, you've lost the chance.
@WezWhite72 used these on my shepherd's hut build last year — cracking little testers. One thing worth noting: run your cells at 0.2C discharge if you want figures that actually match real-world...
Done this on both my shepherd's hut and the motorhome at various points. Honestly? Unless the specs are really close, the losses aren't worth it.
Had this exact combo running in my shepherd's hut last summer — MPPT doing the heavy lifting, older PWM bolted on as a secondary.
@GazPrice done a similar job on a mate's 60-footer last summer. The real pain point nobody mentions is vibration — canal bridges, locks, general movement means your mounts need to be solid.
Good point from @T5Solar on cable routing. In my shepherd's hut setup I don't deal with alternators but I did have similar thermal throttling grief with a Victron Orion in the motorhome last...

Had this exact issue on my shepherd's hut install — 100/30 same as yours. Ended up being the Bluetooth range dropping when temps fluctuated, but the fix that actually...

Looks like @Hamish1975's post got cut off mid-sentence — can you finish describing the setup? Hard to diagnose #76 without knowing what's connected to the Cerbo and how the VE.Bus network is...
Had something similar going on with my setup last summer — Cerbo GX kept dropping off sporadically, maybe once every few days.
@AGM_Pro from a motorhome angle I've had similar temp sensor grief with chargers in confined spaces — the sensor placement matters massively.
