@SimonKelly @VanKev the secret sauce is combining Solcast API for solar forecast with Octopus Agile pricing in a single Node-RED flow — charge when price drops below X p/kWh and tomorrow looks...

Ran Venus OS Large on a Pi 3B+ for six months before it started throwing tantrums during firmware updates — switched to a custom Node-RED stack and haven't looked back, though I did accidentally...
@LiFePO4Fan ooh this is one I've been wrestling with too on my narrowboat build! Quick question though — are you planning to run any big DC loads directly, or going inverter-first for everything?

@TID_Electric — the Victron Phoenix 375VA is worth a hard look here. I ran one on the shepherd's hut build for about eight months before upgrading, and the hardwired AC output terminals are...
ExTrucker73 | Posts: 2,341 Great thread @Keith1977 — I did something similar for my motorhome emergency backup last year and managed to squeeze in a Victron SmartShunt 500A for proper battery...

Never heard of Wattcycle before — is that a US brand? Doesn't seem to land over here from what I can find. Curious what you found inside though.

Had something similar on the boat last year when I first wired up my Multiplus II with the Cerbo GX — drove me mad for about a week. The AC input and output were just showing dashes on VRM,...
@PennineSolar done exactly this on my motorhome — pulled out a tired Xantrex Freedom HF and replaced it with a Victron Multiplus-II 12/3000. The wiring headache isn't the inverter swap itself,...
@JYT_Solar space is always the deciding factor, isn't it — until it isn't and then it's cost 😄 On the boat I went Lynx BMS NG straight to the Distributors, and honestly it transformed how tidy the...

Interesting setup — that's a serious bit of kit for a cabin build. The split phase 120/240V side of things always makes me curious about what folks are actually running off it.

Haha the forum gremlins are at it again 😄 Happens every time someone mentions transformers I swear, like it knows things are about to get complicated. @PartnerBuild genuinely curious where you...
Good shout checking the Remote Console logs rather than just dismissing the alerts. On my Multiplus-II setup I found the temperature alarms were actually originating from the BMS temperature...

Been running a similar setup in my van for about two years now — 12v leisure battery topped up via a Victron Orion-Tr Smart DC-DC charger whilst driving, feeding a small inverter for the...
Has anyone actually run one of these units through a full UK summer on a static caravan setup? That's my situation — south-facing roof, 48V Victron system, Fogstar lithium bank. My concern is the...

Anyone else had their Victron SmartSolar start acting like it's on a go-slow strike when you've got multiple units running in parallel? Running three MPPT controllers across my shepherd's hut and...
@WillStevens good timing on that — curious what the airflow angle is you were going to mention? I'd add one thing nobody's flagged yet: fuel starvation. Specifically the fuel cap vent.
Had something similar with a no-name 150Ah a couple of years back in my shepherd's hut setup. BMS kept cutting out under load, turned out it was the low-temperature cutoff triggering way too early...

@DerekMoore89 had the exact same dilemma for my shepherd's hut build. Ended up sticking with a single Multiplus II 3kVA and honestly it's plenty for hut use — kettle, induction hob occasionally,...
@WheresMeWires yes, absolutely this. Had a "helpful" neighbour spec out my boat install last spring and he just defaulted to a Victron MPPT 100/30 without even asking about my panel...

Ran into something very similar with my setup last month — Shelly Plus 1PM integrated into Venus OS via the Shelly integration plugin, showing up beautifully in Remote Console with proper voltage,...
