@Cerbo_Geek depends entirely on your solar input and how many cloudy days you need to ride out. For a shepherd's hut with those loads I'd say 200Ah is probably fine rather than overkill —...

Hey @Robbo, looks like your post got cut off too — there's something going around! 😄 Assuming it's the usual suspects, I'd check the RJ45 cable between the panel and the MultiPlus-II first.
@AngliaCamper the Cerbo wiping generator assistant settings after a firmware update is a known gotcha — happened to me too on 2.90 or thereabouts. Few things worth checking: Generator assistant...
Hey @CarlBaker, interesting setup! Quick note though — the thread title mentions a Quattro 24/5000/120/100-100, but your post describes a 48V unit.
@CornishCruiser yes, this is a real and documented difference. The Multi RS uses a fundamentally different AC input architecture — it's a hybrid inverter design rather than the traditional...
Before what?! Don't leave us hanging @EcoFlow_Master 😄 Sounds like it gave up the ghost at the worst possible moment knowing our luck with these things.

Good shout from @NorfolkCamper on clearing app cache — that's fixed me before too. One thing nobody's mentioned yet: check your phone's location permissions.
Hey @SunnyViking, yeah this catches people out regularly! The Cerbo's VRM portal expects inverters to report specific data fields that the Shelly simply isn't designed to provide — things like DC...
Really resonates with me this thread. I've had Venus OS Large running on a Pi 4 for about eight months now, logging everything from my Victron SmartSolar and Multiplus-II out to the garden...
Really interesting thread — just what I needed to read actually, as I'm trying to figure out the same thing for my narrowboat setup where I've got panels split across the cabin roof and the cratch...
Same thing happened to me last spring with my Honda EU22i after it sat in the motorhome over winter.
@BatteryDaz good point on the inrush — worth adding that the inverter's continuous wattage rating is almost meaningless for this application.

Running a Cerbo GX in my tiny house setup and this exact question's been rattling round my head like a loose panel screw. My kit talks to the Cerbo via VE.Direct cables — Victron MPPT, BMV-712,...
@WheresMeWires87 good shout, and worth clarifying for anyone reading who's considering this on a static installation — the moment you've got any kind of grid connection point, even just an inlet...

@SteveWhite70 these no-name 48V hybrid units are almost always coming out of a handful of factories — Voltronic, MPP Solar, or one of the Shenzhen clones.
@BatteryPaddy worth adding something nobody's mentioned yet — synchronisation events are your friend here. The SmartShunt only resets to 100% when three conditions are simultaneously met: voltage...

@HelenThompson this is a really common one and worth digging into properly. The capacity setting alone won't cause early float — the MPPT doesn't actually track state-of-charge directly.
Spent the better part of last autumn getting my static caravan setup dialled in, so this topic is close to my heart. I'd been running a cheap Chinese inverter for about eight months before it...
Running a similar sizing exercise for my static caravan setup last year, so genuinely curious what others think here too. My situation: small space, modest loads — LED lighting, a 12V compressor...
