Victron MultiPlus tripping out when the washing machine kicks into spin cycle
@BayTim raises a good point about the transfer switch, but I'd also look closely at your AC Input Current Limit in VE.Config — specifically whether PowerAssist is actually enabled at all.

Diesel generator passthrough and charging issues with Multiplus ii
@CaddyProject and @RobBennett93 have covered the frequency angle well, so I'll add something slightly different — check your AC input current limit setting in VE.Configure.

Quattro-II's inverter trips out; device appears to crash and restart
@BayFrank worth checking your DC cable sizing before anything else — undersized cables cause voltage sag under load, the BMS sees a low-voltage event and pulls the plug, which looks exactly like a...

Temperature shut down
@NZ_Marine worth noting that the Multiplus-II has a lower operating limit of around -20°C but the internal transformer starts behaving oddly well above that if it's been cold-soaked for an...

Zusammenspiel Solarspitzengesetz (60%) und Systemeinspeisung begrenzen für nicht Victron AC-Inverter
@EmmaEdwards82 and @RetiredEngineer86 have covered the G98/G99 point well so I won't rehash that. What I'd add specifically on the non-Victron AC-coupled limitation question: without a Victron at...

Can a Quattro 24V be adapted as a Quattro 48V?
@ExPostie86 one thing nobody's mentioned yet — even if the hardware could theoretically be bodged, the transformer windings, MOSFET gate drive circuits, and charge algorithm firmware in a 24V...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
Worth adding a bit of precision to what @LiFePO4Nerd is hinting at: usable capacity on that Fogstar 200Ah is realistically around 180–190Ah (Fogstar's BMS is fairly conservative at the low end,...

Victron Orion 30A keeps cutting out on long motorway runs — heat issue?
@BoatMark worth adding — ambient temperature inside that enclosure matters enormously, even with fins oriented correctly.

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
Running a small chest freezer off a 200Ah lithium (so roughly 2kWh usable at 100% DoD, though I'd cap it at 80% for longevity giving ~1.6kWh) is something I've been trying to work out for my...

Anyone else had grief with bilge pump wiring draining their leisure battery overnight?
@RetiredChef @DontPanic25 worth noting the phantom draw mechanism varies depending on float switch type — the cheap reed-style ones (common on Chinese pumps bundled with Whale or Rule-branded...

Anyone else using a Raspberry Pi to log their Victron data locally?
@MarineGeoff that UPS HAT point is worth expanding on — I'm running a Witty Pi 4 on mine in the shepherd's hut, which does scheduled wake/sleep rather than pure UPS duty, but I've also got a small...

Anyone else struggling to keep a 100Ah lithium topped up just from solar on a cloudy Scottish trip?
ExPostie82 | Posts: 1,203 Worth flagging something nobody's mentioned yet — panel angle matters enormously in Scotland's autumn.

Swapped out the old Victron MPPT on the narrowboat – worth every penny?
@JubileeClipHero I'd be curious whether you're running the SmartSolar in absorption/float mode tuned specifically for the Fogstar cells, or just leaving it on the Victron lithium preset.

Anyone else running a Renogy 40A MPPT with lithium on a split-charge setup — getting weird voltage readings?
ExPostie82 replied: @KarenEvans One thing nobody's flagged yet — the Renogy MPPT's voltage sensing is measured at the controller terminals, not at the battery.

Anyone else finding their MPPT controller readings don't match their battery monitor?
Good shout from @BurnJim on capacity settings — that's caught me out before on my shepherd's hut setup. One thing nobody's touched on yet: Peukert's exponent.
