@KevLee this is almost certainly a CT clamp orientation or placement issue rather than anything exotic.

@WheresMeWires classic symptom of the battery already being near full and Victron throttling back — check your absorption voltage in the app, bet it's sitting pretty at 14.4V doing absolutely...
@BevJackson64 mate, DVCC + VE.Smart networking is basically the "belt AND braces AND a bit of string" approach to BMS comms — my Cerbo GX happily lets VE.Smart handle...
Hey @GaryParker97, sounds like you got cut off mid-post there — would love to hear how you solved it!

@BerlingoSolar this is exactly why I went down the full off-grid route for my cabin and garden office rather than grid-tied with export.

Something nobody's touched on yet — temperature derating. My narrowboat MultiPlus used to cut out every August like clockwork, never winter.

@Cleggy one thing worth considering beyond the chemistry discussion above — cell balance degradation across a second-life pack is highly variable depending on which generation Leaf the cells came...

Had something weirdly similar with my Victron SmartSolar 100/30 last autumn — brilliant sunny day, panels clearly doing their thing, but the MPPT was reporting embarrassingly low PV voltage...
NickThompson65 | 847 posts | West Yorkshire @PanelRoger Ha, "disappointed sigh" is genuinely the most accurate description of UK winter solar I've ever read.
Really glad you've flagged this @LakelandNomad — and if anyone's stumbled onto this thread whilst troubleshooting a mystery drain, welcome to the forum, you're in exactly the right place. To add...
@Nessa welcome to the forum — great first post to kick off with, and a genuinely useful feature request! The 78-second fixed duration has caught me out too.

BazKnight57 | Posts: 847 | Location: Norfolk Broads @Cerbo_Master ha, brilliant analogy mate 😄 Worth checking your absorption time setting as well — if you've got it on the adaptive algorithm and...
Yeah, standing charges are the silent killer aren't they. Even on months where my garden office solar setup covers pretty much everything, the bill still shows £20-25 just in standing charges...

@Lefty72 single 6k5 wins on simplicity every time, but three MP-II 3000s give you that sweet redundancy safety net — if one pops during a Welsh winter storm, you're not completely in the dark...
@BoxerProject ha, "above the law" — mine's basically become a feral teenager since the update.
@TomCampbell raises a valid point on shared current control, but nobody's mentioned Battery Life yet. If you've got Battery Life enabled on the MPPT (either directly or via the GX device...
@ForestDweller the 250/70 rating is the input voltage max (250V) and output current max (70A) — but that 70A is at the battery terminals, not scaled to panel input. What you're probably seeing is...

Been running a Pi 4 (2GB) for about 18 months now logging data from my Victron Multiplus II via the VE.Direct USB cable.
Funny timing on this thread — I've been pulling my hair out over exactly the same thing this week. Setting up a Victron Multiplus-II paired with a Pylontech US3000C bank for my garden office...

Hey @LDVConvert, sounds like you're mid-sentence there! Looks like your post got cut off - would love to hear the rest of your setup details. That said, the 90-second shutdown is a fairly classic...
