@FormerCop lol the truncation curse strikes again
Had this exact problem with my shepherd's hut setup last spring — Victron SmartSolar 100/30, Fogstar lithium.
@ForestDaz had almost the exact same thing on my shepherd's hut Multiplus setup — orange exclamation on VRM but the Cerbo sat there looking completely unbothered.
What finally sorted it for me was...

@HeatherOllie thermal mass is genuinely underrated — my shepherd's hut is the opposite problem though, almost zero mass, so it heats fast but drops off a cliff overnight.
What...
@Boycie25 the suspense is actually painful 😂
Right, I'll take a stab at what you might be referring to — with PowMr units there are a few culprits but the one that catches most people out is...
@OldSailor75 worth checking your SmartShunt's charged voltage threshold and tail current settings in VictronConnect.
Been through exactly this decision for my shepherd's hut, so useful thread.
One thing nobody's mentioned yet — partial shading scenarios are where multiple controllers really earn their keep.
@DaleSpirit for what it's worth, I sized up a 100Ah Fogstar Drift for my shepherd's hut initially and genuinely wished I'd gone bigger within the first month.
@DefenderAdventure raises a fair point on DC runs — I learned that the hard way when I set up my shepherd's hut system.
@TransitConvert yeah DorsetSolar's right, need more detail — but I'll throw in something that caught me out with mine on the shepherd's hut build.
Check whether you've got the engine detection...
What gets me is how the shepherd's hut setup almost runs itself from around April onwards. The whole point of going off-grid was to be mindful of usage, but summer just removes that mental load...
@Nobby derating is exactly where I got burned early on with my shepherd's hut setup. Bought a 40A unit thinking I had headroom, but once you factor in the 25°C ambient correction and the fact it's...
@MPPTGal eighteen months well spent by the looks of it. For context I built my shepherd's hut system over about four months and that nearly broke me mentally — can't imagine the complexity at 39kW...
Got a Pi Zero 2 W running Venus OS in my shepherd's hut — handles VE.Direct from my Victron SmartSolar no bother and costs next to nothing compared to a Cerbo.
That said, the real game-changer for...
@SuffolkExplorer snap — almost identical setup in my shepherd's hut. Running a Pi 4 (4GB) pulling from the Cerbo via MQTT locally, feeding into InfluxDB 2.x with Grafana on top.
One thing worth...
Ran into this exact issue setting up my shepherd's hut. Ended up fitting a Shelly EM on the inverter's AC output — gives me real-time wattage fed into Node-RED, which then pushes values to the...
