Great thread, this. @Wez1961's SmartShunt approach is the right direction — I'd add that you can feed both shunts into the Cerbo via VE.Direct and then use the 'has DC system' option in the...
@Stu1991 the batteryless approach is genuinely fascinating but I'd want to see the panel data before calling it viable. The fundamental problem isn't cloud cover gaps — it's the rate of change.
@BoatMark worth clarifying what Ekrono expects at the application level when there's no inverter node present — in my tiny house setup I ran it meters-only for about four months before adding a...

@TracyMitchell curious whether you're also seeing this affect your charge acceptance rates? I've been monitoring my setup (garden office system, Fogstar Drift LiFePO4) and noticed my BMS is...
@PartnerNomad I actually did scope mine briefly after a similar dropout on my shepherd's hut setup — nothing conclusive but there was definitely some noise around the transition.

Been wondering whether to add this to my cabin setup for a while. Currently just relying on the Victron app via Bluetooth which is fine day-to-day, but I lose all historical data if I don't...
Really useful thread this. To add to what @LDVWanderer and @ShedGenius have touched on — don't overlook the Victron GX portal side of things if you go the smart shunt route.
@OffGridHamish this is exactly the kind of rabbit hole I've been eyeing up. Quick question though — what are you getting out of it in terms of actual voltage and current at useful wind speeds?

Yeah this catches loads of people out. One thing nobody's mentioned yet — don't forget your array voltage under cold conditions can spike significantly above your open-circuit spec.
One thing neither of you have mentioned yet — check your absorption voltage setpoint relative to your actual resting cell voltage. On my setup I found the default 57.6V (for 48V) was far too close...
Ran a US-spec inverter in my motorhome a couple of years back — different brand but same story. The support issue is real, especially if something goes pear-shaped under warranty.

Ha, third time asking but I genuinely want to know too @Tommo! Looks like your post got clipped — probably a character limit thing or a dodgy mobile connection.

My Cerbo GX once woke me up at 2:47am with a relay click and I'm still not over it — turned out it was "optimising" against an Agile tariff slot that had already passed, which is exactly...

DailySolar | Posts: 2,341 @AlanWard Something both @IslandDweller and @LindaLamb are dancing around — voltage sag under load is almost certainly your culprit. The Phoenix 24/1200 can pull ~55A...
@OffGridHamish done exactly this on the narrowboat, mate. Indesit motor off Facebook Marketplace for a fiver.

So what's the actual Voc figure people are working with when the panels are stone cold on a winter morning?

@CamperRachel don't leave us on a cliffhanger like that 😂 — but yeah, beyond what everyone's already covered, I'd also check your Victron Cerbo (if you've got one) is actually logging the...

@ShortCircuit is right about the SOC issue but there's a practical workaround — use a SmartShunt on each bank separately, then feed only the LiFePO4 shunt to the Cerbo as the "main"...
@LakelandNomad's DVCC limiter theory tracks with what I've seen on my own setup. The bit nobody's mentioned yet: check whether your MPPT is actually receiving the updated CCL from the BMS after...

@TracyMitchell your MultiPlus isn't grumpy, it's just British — performs perfectly fine until the temperature drops and then suddenly it wants a hot cuppa before doing any work 😄 Jokes aside,...
