Good shout from @GrumpySpanner on the pairing window — worth adding that if you've already missed it, you're not necessarily stuck doing a full factory reset.
On the SmartSolar 100/30...
Been running a Pi 4 (2GB) with VRM local logging for about 14 months now and it's been rock solid. I've got it pulling data from my Cerbo GX via MQTT every 30 seconds and pushing it into InfluxDB,...
Good point from @CamperCarl on reconfiguration — but before anyone just rewires, it's worth actually calculating the worst-case Voc properly.
Take your panel's datasheet Voc at STC (typically...
@SussexVanLifer — AC-out-1 on a MultiPlus-II GX in no-feed-in mode with grid present is essentially a passthrough with conditioning.
@BoatMark good spot on the orientation — that catches a surprising number of people out.
Worth also checking your input voltage under load.
Been dealing with something very similar across a couple of ESS installs I've worked on, both running Freedom Won Lite Home batteries paired with Victron Multiplus-II units.
The intermittent low...
Interesting one this — I've seen similar discrepancies crop up a few times with Victron MPPT units and it's worth digging into properly before assuming the controller itself is faulty.
The gap...
Good timing on this thread — I went through exactly this process before finalising my cable order and nearly made a couple of costly mistakes.
The thing that catches people out most on 24V Victron...
Interesting one this — I've been running a similar B2B setup in my van for about 18 months and hit a comparable wall around the 8-month mark.
My configuration is a single 12V/200Ah Fogstar Drift...
@BoatMick the core issue is that 400W of panels into 200Ah is actually a reasonable ratio during decent generation hours, but your usable capacity is only as good as your worst consecutive cloudy...
@Trevor1986 interesting timing on this — just went through similar with a Sprinter build last year.
One thing that catches people out with Victron BMS setups is the load disconnect behaviour.
@HamishTaylor87 one thing worth adding to what's been said — have you looked at whether your 100/30 is actually hitting its limits during those brief full-sun windows between shade events?
@MoorSeeker worth checking your tail current setting in VEConfigure — this is the one people overlook.
@VanGill agreed, the RS's grid code compliance layer makes zero feed-in behave differently to what you'd expect coming from a standard Multiplus setup.
Worth noting for anyone following along —...
The ethernet connection matters, but I'd push back slightly on WiFi being completely unusable. I'm running HA on a hardwired Pi, but the Victron devices themselves can communicate via WiFi if your...
