@ExSquaddie49 makes a fair point re DVCC but worth checking your absorption voltage settings too — if the Orion's set higher than the MPPT it'll basically be fighting itself.
Had exactly this mess...
@Macca was probably gonna say combo — insulation plus ventilation. People always treat them as separate fixes but they're not.
Done the same battle in my static.
@PaddyDavies what firmware are you on? Victron pushed a few ESS updates last year that caused weird grid draw behaviour even with a full battery.
Yeah @CrispyMechanic is on the right track but I'd add — the SmartShunt is only as good as your initial setup.
@ShesBeRight yeah had something similar on my static van setup after a Victron update a while back. Grid code defaulting to NONE is annoying but easy enough to sort in VEConfigure — just set it to...
Done the same on my static and a motorhome — and honestly the thing that gets me every time is how the voltage holds flat right across the discharge curve.
@TracyAllen yeah the smart alternator thing is well documented at this point tbh
What I'd add — if you've ruled out both thermal and the smart alternator nonsense, check your cable run.
@BatteryTim yeah usable capacity is the big one nobody talks about until they've lived it
Had 200Ah of AGM on the motorhome. Thought I was sorted.
Yeah the 78 second thing is genuinely baffling design choice. Like who decided that was the magic number?
Running a SBP-100 on my static and I've bodged around it with a relay timer module off...
@Julie1991 honestly for a static caravan this is massive overkill, but I get the appeal of the tech.
@LDVNomad done this exact thing on my static caravan. One thing nobody mentions — generator output quality matters a lot.
@Titch never heard of the Yixiang MB56 tbh — is that even available UK side or are we talking grey import territory?
@LDVNomad tried something similar on the static van a few years back. Honestly? More hassle than it's worth unless you've got loads of time to burn.
The rewind alone nearly broke me — getting the...
@MasterWanderer had the same issue in my static — shoved the Orion under a shelf like an idiot. Moved it to a vertical mount on the bulkhead with a small 12v fan running off the same circuit and...
Never really got the appeal of swapping away from Victron tbh. Yeah Sterling know marine, fair enough, but Victron's ecosystem integration is hard to beat once you're in it — Cerbo, MPPT, BMV all...
