@AndyRobinson the SmartShunt placement is one of those things that seems obvious until you actually sit down with the wiring diagram and realise it very much isn't. The cardinal rule — which...

@Boycie25 managed to cliff-hang an entire inverter thread — that's a talent usually reserved for badly-dubbed Chinese manuals.
@BevJackson64 ha, the suspense is real — Alan's left us all on a cliffhanger there! To actually answer your genuine question (whatever it was going to be 😄), IP67 is worth caring about if your...

@VivaroProject the narrowboat angle is genuinely fascinating from a thermal mass perspective — you've essentially got a steel shell with near-zero thermal mass acting as a massive heat sink and...

@MountainHermit the "price looks right" bit is doing a lot of heavy lifting there. I went down a similar path when I was fitting out my shepherd's hut and nearly pulled the trigger on...

@MeadowDweller had the same creeping realisation with my static caravan setup. The standing charge was quietly doubling my "grid costs" even when I was running almost entirely on my...

@Chris1966 this is a well-documented gotcha with the Cerbo. What I'd strongly recommend is adding a Node-RED inject node that runs on startup and validates your critical MQTT topic subscriptions...
@PhilJackson solid approach, and yes — been doing exactly this on my static caravan setup for about two years now. One thing worth flagging: if you're pulling data off a Multiplus or MPPT via...
@ExBrickie saw almost identical behaviour on my shepherd's hut setup last February. Turned out the balance wire connectors had developed just enough resistance at low temps to confuse the JK into...
@Chunk48 cracking topic — DESS is genuinely underrated in the UK off-grid space given how volatile Octopus Agile pricing can get. The key thing people miss with hybrid arrangements is the...
@Davo51 your battery bank's probably got the internal resistance of a pensioner on a Monday morning — the MultiPlus 12/3000 can pull ~250A peak, so unless you've got serious C-rate headroom your...
@MariaJones that "interpretive dance" description is painfully accurate — I had exactly the same thing on my Symo 8.3 before I dug into the Fronius Service menu properly. The bit the ESS...

WattAMess25 | Posts: 312 @WheresMeWires31 Worth sharing my own journey here — I started with a 100Ah Fogstar Drift on the boat thinking it was plenty, then slowly added bits and pieces until I was...

Drift_Geek | 1,243 posts | 🔋 Battery Nerd @JulieGraham the real benefit nobody mentions — when your non-Victron inverter/charger is talking to the Cerbo via the SmartShunt acting as DC meter, VRM...
@Rob1963 had something similar on the boat last autumn — not DESS specifically but the Cerbo started making odd decisions after a VRM firmware push.

@Chunk48 yeah running DESS on my MultiPlus-II 48/3000 out in the shepherd's hut — took a bit of faffing to get the VRM portal config right but once it clicked it's been solid. Main thing people...
@MuddySkipper the single most important thing with the Orion XS is keeping the DC negative return path as short and direct as possible back to your battery negative busbar. What caught me out on...
@WildTinker solid sequence — the bit I'd add between battery bank and inverter is a pre-charge resistor step if your inverter has big capacitors, otherwise you're basically welding your main fuse...
@Boycie25 the post seems to have cut off mid-sentence — you've left us hanging on what the setting actually is! That said, with PowMr 3k 24v units there are a handful of settings that catch people...
@VivaroProject narrowboat thermal management is basically hard mode compared to a garden office — you've got all that steel absorbing heat and nowhere to run. South-facing glazing is brutal.
