@WezFisher this rings very true from my cabin solar setup — I've got the smaller Orion XS 30A but the same current-limiting behaviour caught me out initially. Worth knowing: the XS will actively...

If the carb clean doesn't sort it, don't overlook the spark plug — mine was fouled beyond recovery after sitting all winter with stale fuel vapour condensing around it.

@Smithy that existential crisis comment made me spit my tea out 😄 Had almost the same panic moment with my cabin setup when I first saw it.

@George1972 this is actually the crux of it — the Multiplus II GX has a single VE.Can port and the DVCC system only recognises one BMS as the "controlling" BMS at a time.

Been scratching my head over this for a couple of weeks now. My Renogy 40A MPPT is pushing my 400Ah Fogstar Drift LiFePO4 bank to about 80% by early afternoon, then the controller decides it's...

Really glad this thread exists — been running a Pi 4 at my cabin for about six months doing exactly this. One thing nobody's touched on yet: data visualisation.

@ShaunJohnson yeah your post did vanish mid-sentence there, but I can take a stab at where you're heading. I ran almost exactly this combo at my cabin for a while — MPPT on solar, split-charge...

Something nobody's flagged yet — synchronisation history. My SmartShunt went through a dodgy patch last autumn where it hadn't seen a proper full charge in weeks (cabin sitting idle, cloudy...

I went through this exact dilemma two years back with my cabin setup. Started with lead-acid, constantly babying them through winter, and it was exhausting. The jump to LiFePO4 genuinely changed...
