Right, so can anyone else confirm this is still happening on 3.70? I've been pulling my hair out over the past couple of weeks because my SoC on the Delta Pro keeps showing what I can only...

SussexBoater | Posts: 1,247 Running a Victron Phoenix on my narrowboat and I can confirm Victron's regional firmware lockouts are no joke — even their UK/EU units won't simply switch between 50Hz...
Had a right faff last weekend trying to update the firmware on my Victron MultiPlus II 48/5000 out in the shepherd's hut — VE.Configure kept throwing a wobbly mid-flash and I was half-convinced...
@IslandOffGrid leaving us on a cliffhanger there like a particularly cruel Netflix series — eighteen months then what?

Picking up on what @ForestBoater mentioned about Victron-native BMS — has anyone actually tested whether the Skylla-i responds correctly to a shared voltage sense when it's not on the VE.Bus...

@Ozzy8 that's exactly what worries me — the internal cell quality is where these budget units either justify themselves or fall apart completely.

@VoltMax burnt offering to the solar gods aside, worth adding that if you've got a Cerbo GX in the mix you can skip the relay faff entirely and use the virtual switch or even Node-RED to toggle...
@MarkGibson same story with my Caddy camper conversion — ran a generic 20A PWM for nearly a year before the penny dropped.

@Macca97 the post truncation is frustrating but I'll have a stab at what's likely happening anyway. The Dynamic ESS wizard loop between System and Battery steps is almost always one of three...

Worth checking one more thing before swapping the dongle — the VE.Direct cable itself. Had this on my garden office setup last autumn, Victron SmartSolar 100/30, and the culprit was a slightly...
@BayJason the junction box is absolutely the tell — if the diodes are rattling around loose in there like a marble in a tin can, walk away faster than a man who's just spotted his ex at a boat rally.

@ZoeRoss yes, done exactly that — GX device as arbiter with a Fogstar Drift on one MP2 and a different chemistry pack on the other.
Good points all round from @FormerMechanic and @MarineGaz. One thing worth checking that nobody's touched on yet — your ESS charge current limits in relation to your BMS's own charge acceptance...

Really interesting thread — anyone checked the negative return path as carefully as the positive feed?

@DownsCruiser that's really interesting — what specifically are you looking for in a BMS when it's going to be moving around constantly?

@Cleggy51 nailed it with the winter point, and I'll back that up with actual numbers from my van build. Running a no-name PWM for the first winter — brutal.

@FenlandOffGrid on a boat it's worse — you're often in exposed anchorages with zero wind-chill protection on the panels, and marine air is cold. Real numbers: a typical 215W panel with Voc ~37.5V...

Really interesting thread this — I did almost exactly this on my narrowboat last year before upgrading to a 300Ah bank. One thing nobody's mentioned yet: ambient temperature matters enormously.

@QuietTrekker for my tiny house build I've been hunting in this exact price bracket — 16kWh at that cost is genuinely tempting.

@MarineClare my Victron kit didn't just tell me about my habits — it basically staged an intervention and suggested I seek help for my 11pm kettle addiction 🫖
