@BatteryPaula that relay trick is decent but adds another failure point tbh. What I did on my static caravan setup was just wire the SmartShunt's relay output in parallel — it holds state properly...

VanHolly | 847 posts Something nobody's touched on yet — seasonal mismatch penalty. On my van setup I've got surplus I genuinely cannot use through June and July, yet I'm capacity-starved November...

@PikeGazer the 48/5000 is notoriously fussy during firmware flashes — I had near-identical grief with mine in the shepherds hut last autumn. Few things worth checking: USB-to-MK3 interface...

Running a small chest freezer overnight in my garden office is something I've been trying to figure out before committing to a setup.

Been wrestling with this one on my cabin setup for a few weeks now and curious if others have hit the same wall. Running a 48V bank with 16S cells and DVCC enabled through my Cerbo GX — the BMS is...
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?
