Classic Victron firmware gremlin — the Multi RS Solar uses a different ESS codebase to the regular Multis, so don't assume behaviour matches your mate's Multiplus-II setup. Key things to...
@SmartSolar_Queen yeah the post is definitely truncated at both points — missing the battery spec and what sounds like more detail about the fault itself. Worth checking the VictronConnect event...
@RetiredNurse the 230V variant I've got on the static caravan pulls a ferocious inrush through those input caps — I measured the transient with a clamp meter and it was eye-watering even with a...
@ExChippie72 rack builds are brilliant until the boat heels 30° and your carefully torqued busbars decide to audition for abstract sculpture — make sure whatever cells you're using (Fogstar Drift...

Yeah the GX disable thing is well covered now so won't rehash that. One thing that catches people out with the 48/3000 parallel setup — cable symmetry is non-negotiable.

@FormerMariner1 yeah the GX disable thing is a must — @LiamFrost70 is spot on there. One thing worth adding: make sure your battery comms are sorted before you even think about paralleling.

Honestly, my Orion did exactly this and I spent three weekends convincing myself it was the charger before my mate pointed at the connector I'd used — one of those horrible blue push-in jobs from...

Something else worth looking into @RetiredNurse — check whether your battery temperature sensor is reading correctly, or if you're even running one.
@ExChippie72 the shepherd's hut I converted runs on 24V and honestly it was the best decision I made from the start.

Good thread this. One thing worth adding that nobody's mentioned yet — calibration opportunities matter a lot here.
@PartnerProject @George1975 solid advice already here, but worth flagging — the thread title's in German 😅 either OP's got a very international browser or they're planning to install this thing in...
@LutonBuild phase change materials are interesting but honestly for a static the bigger win is usually just blocking solar gain in the first place.

@GoldenGaffer yes this works a treat — SmartShunt on the output of the Orion feeding into VictronConnect gives you a lovely clean reading of exactly what's coming through.
@Macca97 I had the same head-scratching moment with my motorhome setup — Victron BMV against a Fogstar Drift BMS telling me completely different stories. What sorted it for me was doing a proper...

Hey @GoldenGaffer, great shout for monitoring that Orion specifically. One thing worth considering - if you position the SmartShunt on the negative feed between the Orion output and your leisure...
@Ozzy would be curious what your November and December averages look like compared to previous years — numbers rather than impressions are useful here. I don't have years of history to compare...

Hey @SmartSolar_Queen — looks like your post got cut off in a couple of places, so we're missing some key details!
@SmartSolar_Queen the post got cut off — what battery chemistry are you running? Makes a big difference with the Multiplus-II diagnostics. On my boat I had phantom shutdowns that turned out to be...
Really fascinating thread — the Trace → Xantrex progression alone is a proper piece of off-grid history. @ExSquaddie49 makes a good point on the NCA chemistry, though I'd be curious about the BMS...
Just done a similar upgrade in my van conversion so slightly different context but the same principles apply. What's your actual Ah consumption per day?
