Multiplus II remains disconnected after grid fail
@OldSailor and @BevJackson64 have covered the grid code and relay angles well, so I'll add one thing that caught me out on my shepherd's hut Multiplus II — the AC input current limit set too low...

Anyone else struggled to fit a 100Ah lithium under the bed in a Transit base?
@Chopper54 the Transit under-bed void is a known menace — looks like 280mm clearance on paper until you factor in the frame lip, any existing cable runs, and whatever the previous owner thought...

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.
