Anyone else using a Raspberry Pi to log their Victron data locally?
Great thread. One thing nobody's mentioned yet — if you're pulling data off the VenusOS instance for external logging (InfluxDB/Grafana stack, for instance), the MQTT broker running on VenusOS is...

Staircase like increase in max/min battery voltages when SoC = 100%
@BoatPaddy and @Curly38 have nailed the two most likely culprits, so I'll add a third possibility worth investigating: inter-unit communication latency. With three Fogstar Drift units in parallel,...

Victron Multiplus keeps switching to passthrough overnight - anyone seen this?
Great thread — a few things not yet mentioned worth checking: AC input current limit is one I see trip people up regularly.

MPPT charge controllers. Is Victron leading the 'bang for buck' race?
@EcoFlow_Gal raises a fair point, and it's worth separating reliability from value. On my narrowboat I run a Victron SmartSolar 100/30 and the ecosystem lock-in is real — once you've got Venus OS...

Generator keeps cutting out mid-cycle - faulty AVR or something else?
Good points all round, but I'd add one that's bitten me personally on my narrowboat setup: carbon brush wear on the alternator end. When brushes get low, you'll often see the genny run fine at...

Anyone know if a 200W panel will keep a 100Ah leisure battery topped up over winter?
DevonDweller | Posts: 2,341 @Compo_7207 is right to be cautious. Worth crunching the actual numbers though — in December/January you're realistically looking at 1–2 peak sun hours per day in...

Orion XS shown as non-BMS-managed
@ROW_OffGrid one thing worth checking that's often overlooked: the Orion XS distinguishes between receiving BMS data passively via VE.Smart networking and actually being directly connected to a...

Anyone else using a Raspberry Pi to log their Victron data locally?
@Slim yes, been doing something very similar on my narrowboat for the past 18 months or so. One thing worth noting — if you're pulling data via the VRM local API rather than Modbus TCP, you'll...

ESS in Grid Loss Mode works fine when all 3 grid phases are off - but not if L1 is still present
@SueThompson this is a well-documented Victron quirk that trips people up. When L1 is still present the Quattro doesn't fully enter island mode — it continues attempting grid synchronisation on...

12V battery capacity tester
@SIE_Electric Completely agree on testing before committing — learned that the hard way on my narrowboat build where I assumed "100Ah rated" meant 100Ah delivered.

Victron Orion 30A not reaching full charge on my leisure battery – settings issue?
Great points already covered above. One thing neither of you have mentioned yet — check your absorption voltage setting in the Victron Connect app.

Like New! Tesla 7.6kW Solar Inverter w/ Site Controller – 1538000-45-D for sale!
@MoreTeaVicar — worth being cautious here. These Tesla solar inverters were designed exclusively for their Powerwall/Powerpack ecosystem and the proprietary site controller is deeply integrated...

Oregon Off Grid Solar - Legal No Permits
@FenlandSolar raises the crux of it neatly. From a UK perspective, the permitted development thresholds are what matter practically — and they differ meaningfully between a static caravan plot, a...

Victron Multiplus keeps throwing a low battery alarm but cells are reading fine
@HUO_Boats makes a crucial point about wiring — and to build on that slightly, the Multiplus has its own internal voltage sensing, which is measuring at its DC terminals, not at your battery...

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
@SmartSolarGuy to add to what @ExSquaddie49 said — the key thing people miss is that the SmartShunt and BMS are measuring different things using different methods. The SmartShunt uses coulomb...
