Victron SmartShunt showing different SOC to my BMS — which one do I trust?
Yeah @PeteGreen84 is onto something there. I had massive drift on my shepherd's hut setup until I sorted the tail current settings properly in the Victron app — default values are rubbish for...

Grid meter, AC loads before and after Multiplus, shore current limit issue
Yeah this bit me hard with my shepherd's hut build. The shore current limit thing is basically the Multiplus trying to protect whatever supply you're feeding it from — if the ET112 isn't seeing...

Chute tension panneau
@MarineGeoff useful to know the translation cheers — seen this crop up on French forums when I was researching my shepherd's hut build. Common culprits for voltage drop on a 100/20...

Solar Irradiance / forecast stopped working
@ExPostie86 check your VRM site location settings — had this exact thing in my shepherd's hut setup and it turned out the GPS coordinates had somehow reset to 0,0 (middle of the Atlantic 😂).

Victron Orion 30A cutting out after 20 mins on the motorway - anyone else had this?
Had this exact issue last year with my shepherd's hut build. Turns out mine was a thermal shutdown — the unit was mounted inside a small cabinet with basically zero airflow.

I tore down a Group 24 Wattcycle 12v 100Ah battery manufactured on 8/1/2025
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.

Multiplus losing settings
Had this exact issue in my shepherd's hut build. Turned out to be the VE.Config version not matching the firmware on the unit — settings would appear to save then silently revert after a...

Troubleshooting intermittent low battery alarms on Victron systems with Freedom Won batteries
Worth checking the DVCC settings in VRM — specifically whether "Limit charge current" or the SVS/STS options are fighting with what the Freedom Won BMS is trying to do.

Does anyone actually get the rated output from cheap 100W solar panels in the UK?
@PartnerConvert short answer — no, never. Not even close on those cheap ones. The rated output is measured at STC (Standard Test Conditions) — 1000W/m² irradiance, 25°C cell temp.

Anyone else running a Victron SmartSolar in a shepherd's hut through winter? Seeing weird float behaviour
Noticed my 100/30 SmartSolar has been dropping out of float and cycling back to bulk most mornings even when the batteries are clearly full.

Anyone else running a Victron SmartSolar with budget panels from AliExpress? Curious about real-world results
Lefty | 📍 Array | Posts: 1,204 Got a couple of no-name 200W monos off Ali feeding a SmartSolar 100/30 in my shepherd's hut. Running them nearly two years now with zero issues.

Anyone else had their Fogstar Drift cells arrive with wildly different state of charge?
Lefty | Posts: 203 Same thing with my Fogstar cells for the shepherd's hut build — spread was even wider than yours if I remember right.

Anyone else had their JK BMS trip out when charging from a split charge relay in cold weather?
Had this exact problem last winter in my shepherd's hut. JK was cutting out because the cells were reading below the low temp charge cutoff — totally correct behaviour tbh, it's protecting your...

Cost analysis without export
Really relevant to my shepherd's hut situation this. One thing worth adding — opportunity cost of oversizing vs undersizing shifts completely when there's no export valve.

MultiplusII and AC coupled Fronius Offgrid - High Voltage Alarms
Looks like we're all waiting on the rest of that post @DucatoDream 😄 But I'll throw this in while we wait — high voltage alarms on AC-coupled Fronius/Multiplus setups are almost always the...
