@OakSoul the utility room placement makes sense initially but it does bite you later. Moved my Multiplus-II from a similar spot into the motorhome garage area and immediately noticed the...
Anyone else's sensitive electronics throwing a wobbly every time the MultiPlus-II switches between sources? My tiny house setup has the classic Victron MultiPlus-II doing the juggling act between...
@BoatMick one thing nobody's mentioned yet — inverter efficiency losses. If you're running a 230V combi off a 12V Fogstar via an inverter, factor in roughly 10-15% overhead on top of whatever the...

@SolarRachel this is a well-defined problem and worth pushing Victron on via their GitHub feature requests — they do actually engage with those. The crux technically is that the Quattro's current...

Seen this a few times — don't panic just yet. Inverters cutting out in bad weather isn't always the battery's fault. First thing I'd check is whether it tripped on low voltage or overcurrent.
Been down this rabbit hole for my cabin setup and honestly the same principles apply — you want something that can handle those brutal cranking amps without browning out and leaving you stranded...

TomButler | Posts: 847 | Location: Shropshire @CrafterDream makes a solid point about emergency backup.
@HeatherChild I had exactly this crisis with my shepherd's hut build — agonised for weeks before pulling the trigger on the SmartSolar 75/15. Felt ridiculous at the time. Three years on though?
Bit of a weird one and wondering if anyone else has hit this. Upgraded my Cerbo to 3.75 last week — no other changes to the system — and DESS has been acting oddly ever since.

Been through almost exactly this with my static caravan a couple of winters back — condensation was absolutely relentless no matter what I tried. The thing that genuinely shifted it for me was a...

Had almost the exact same head-scratcher on my narrowboat build last summer. Victron SmartSolar 75/15 rather than the 100/20, but the symptom sounds identical. Panels were reading a healthy...
Standing charges are the real villain here — mine went up again last quarter and I've got a 10kWh Fogstar battery bank sat there doing most of the heavy lifting while the grid connection just...

Hey @ForestDweller, good question! Worth noting though that the Renogy Rover Lite is only rated to 60A charge current, so with a 2000W inverter plus EV charging pulling serious amps, you'd want to...

@XU_VanLife welcome to the wonderful world of "using less but paying more" — the energy suppliers' favourite magic trick! 🎩 It's basically the grid equivalent of a gym membership.

What specific voltage thresholds have you configured in the VictronConnect app? I'm running a similar setup — Orion-Tr Smart feeding a Fogstar lithium in my garden office — and found the default...
@FrostyHiker this is actually what pushed me toward lithium for my static caravan setup — AGM just can't deliver those big instantaneous currents without the voltage sagging badly.
@CallumCampbell55 that smallholding angle rings true. A friend of mine runs a small glamping site in the Brecon Beacons — six pods, a shower block, and a workshop — and she's been piecing together...
@Clive1978 the bit nobody mentions: a 40A DC-DC charger doesn't actually pull 40A unless the alternator and wiring can support it properly.
Good timing on this thread — I had almost exactly this scenario play out in my motorhome last winter when the BMS hard-tripped and killed everything including the heating.
