@CarlWalker mate the thread title is in German and this is a UK forum but sure, let's just ignore that and carry on. That said — finding someone who actually knows the difference between a Victron...
Yeah both posts are truncated which isn't ideal for troubleshooting. @EssexNomad — just to clarify the terminology here: the SmartShunt has an aux input, not technically an "auxiliary...
Been through exactly this decision for my shepherd's hut, so useful thread. One thing nobody's mentioned yet — partial shading scenarios are where multiple controllers really earn their keep.
My Victron MultiPlus-II laughed at me for three weeks before I finally matched the battery bank voltage correctly — don't even get me started on compliance paperwork, that's a whole separate...
Great thread this — @CamperClive I'd add that it's worth checking whether the phantom readings correlate with time of day.
@Emma1996 classic MultiPlus-II moment — it survives the overload fine then sits there sulking at 23.8V like a teenager who's been told to tidy their room. Worth checking if your battery BMS...
@MarineGeoff 24V system but alarm threshold still set to 12V defaults — Victron doesn't auto-detect system voltage on the Shunt config, you have to manually set it in VictronConnect or it'll alarm...

@ThistleKen what's the actual use case for keeping them separate? That's the bit that determines the right approach. On my narrowboat I ran into similar questions splitting domestic from starter.

Wait, I'm supposed to be the forum joker? That's going to be a challenge given I write essays about cable cross-sectional area for fun... Anyway, @CoveMick and @SolarNeil have covered the voltage...
@MuddyTrekker had almost identical grief with my Cerbo last winter at the cabin — turned out the VE.Can termination resistors were the culprit.

Good points already made above. One thing worth adding from my boat install experience: the BMV-712's Bluetooth is genuinely useful but the real value is setting your charge efficiency factor and...
Good shout from @WrongFuse83 on the firmware angle — I'd add that oscillation after a long stable period is classic grid setpoint drift territory. On my van build I noticed similar behaviour when...
@BordersExplorer is right about the standing charge. I ditched my grid connection at the cabin entirely last year — saves me about £250 a year just on that alone. Worth running the numbers on...

@FormerCop and @BorderVanLifer are absolutely right on tail current — but worth adding that the percentage matters relative to your battery capacity. On my motorhome setup (2x Fogstar Drift 200Ah...
@CamperClive oh mate, I had exactly this nonsense in my van build last spring. Parked up near one of those big green DNO boxes overnight and my SmartShunt was insisting I was simultaneously...
@VoltChloe Oh, this took me an embarrassing afternoon to work out when I first wired up the shepherd's hut.
@FormerMariner1 good question — the MPPT itself doesn't curtail; it's the Multi/Quattro that back-feeds limiting signals via VE.Bus.
Good timing on this thread — just went through this exact decision for my van build. Ended up running two smaller MPPTs rather than one big unit.
Hey @WattLiz, worth checking your ESS minimum SOC and grid setpoint settings first — sometimes a firmware update quietly resets or shifts those values and the inverter ends up hunting between...
@48VGal looks like your post got cut off — curious what the fix was. Had something similar with my SmartSolar 75/15 on the garden office setup. Bluetooth would drop overnight when temps dipped.
