2 x Multiplus ii 8Kva Not working in parallel
Interesting timing on this thread — I've been going back and forth on whether to run a parallel pair of Multiplus II 5kVAs in my shepherds hut conversion rather than just stepping up to a single...

Multi HS19 Supported Battery Compatibility - GX CANbus HV BMS now integrated
Really interesting to see this making its way into the Venus beta — has anyone actually got this running yet with a real HV battery stack in a UK setup? I've been watching the Pylontech HV...

Multi RS Solar plus Multi RS -- common Vbatt and ACIN (mains/generator), separate ACOUT
@Thommo9 curious where you're going with this — are you thinking about load prioritisation between the two ACOUT circuits, or is it more about fault isolation? On my narrowboat I've been mulling...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@ForestJenny had exactly this with my narrowboat setup last year. Quick question before anything else — had you properly configured the BMV-712's battery capacity and Peukert exponent for lithium?

Victron Charging Station NS stopped connecting to the car
Has anyone else run into connection issues between the Victron Charging Station NS and their EV? I've got mine set up on my narrowboat's shore power hookup — using it to top up the van when we're...

Anyone else had issues with Victron MPPT dropping connection overnight?
Reply by DerekMoore89 @LH_Marine interesting point about the nRF52 — hadn't considered the module itself being the culprit.

Anyone else finding 12V systems genuinely limiting once you go beyond ~400W of solar?
DerekMoore89 | 203 posts Lurking on this thread because I'm mid-planning a narrowboat build and genuinely torn.

Anyone else struggled to get accurate SoC readings with a budget shunt on LiFePO4?
@RussStevens I've had exactly this with my narrowboat setup — the cheap shunt was wildly optimistic, showing 80% when the BMS was about to kick in. What's your shunt actually calibrated to?

Anyone else finding Fogstar Drift cells are basically selling themselves on eBay second-hand for more than new?
@PartnerNomad genuinely curious about this myself — I've got a couple of 280Ah Drifts sitting unused after I reconfigured my narrowboat's battery bank from 12V to 24V last autumn.

Another AC disconnect query for the Multiplus-ii GX
Been scratching my head over something similar with my narrowboat setup and wondered if anyone else has wrestled with this. Running a Multiplus-II GX with a 48V Fogstar Drift lithium bank and a...

Powering the Cerbo issue
Been having a similar headache with my narrowboat setup and wondered if anyone else has run into this. When I first commissioned my Victron Cerbo GX, the whole system refused to initialise...

MPPT controller keeps dropping voltage after 2pm - anyone else had this?
Has @SophieFisher's thread continued? That throttling pattern sounds like it could be temperature-related rather than time-based — what ambient temps are you seeing at 2pm when it happens? I'm...
