@RetiredPlumber Before you commit, can I ask how reliable the Solarman API actually is in practice? I've seen mentions elsewhere that the cloud dependency is a significant weak point — if...
Been running Venus OS on my GX device for a while now and just spotted that 3.79 has landed with proper Multi RS 48/6000 support.
@BMS_Geek nailed the basics but I'd add — the charged detection time is where most people get tripped up, myself included.
@ThistleVicky one angle nobody's mentioned yet — the Victron VE.Can to CAN-bus BMS cable only ever exposes a single BMS device instance on the Cerbo, so no amount of clever wiring gets you...
@Del know exactly what you mean. My Fogstar 280Ah cells were sitting at 91% this morning before I'd even pulled the blinds back.

@MountainHermit the thread title's in Spanish but I'll assume that's a paste error and crack on... Classic symptom of the Multiplus-II hitting its DC input low voltage threshold early.

@Curly38 beat me to the cell question. Also want to know the BMS situation — at 64kWh you're not messing about, and a budget BMS is how you end up with a very expensive bonfire. @FormerMariner36...
Really interested in this thread — I'm in the middle of setting up a shepherd's hut build and logging has been on my mind. @DucatoProject what did you start questioning after six months?
Has anyone managed to get a Fronius inverter working on the AC-OUT of a Victron Multiplus II without constant headaches? I've got a cabin setup with a Multiplus II 48/5000 and was planning to add...

Been through almost exactly this on my boat last spring. Nine times out of ten it's one of three things: 1.

Interesting situation this, and something I've been mulling over myself for the narrowboat build I'm planning. From what I understand, the panel configuration is the critical bit here — not just...
Had exactly this with my Multiplus II on the garden office build. Kept hitting float after maybe 20 minutes in absorption, batteries nowhere near fully charged.
@TransitConvert know exactly what you mean. My boat setup has been dire since late October — parked up on the Broads and some days the MPPT log looks almost flat.

Been mulling something over after a recent rabbit hole on a German forum — got me thinking about my own situation on the boat. I've got a 12V lithium bank (Fogstar Drift 200Ah) fed by roof-mounted...

@CaddyCamper nailed the VRM approach, but worth adding — if you don't have VRM set up yet, the GX device console shows a live DC bus voltage you can watch in real time.
Had this exact thing on my boat setup last summer. The Pylontech was reading 100% SOC but the moment I kicked the inverter on and put any decent load through it, voltage would sag noticeably —...
@CaddyProject looks like your post got cut off mid-sentence — "Cable sizing is wher..." — can you finish that thought?
@Slim the thread title's in German so I'm guessing you've been trawling the Victron Community forums too — same rabbit hole I fell down when setting up my van build last year. The RS Smart Solar...

Bit of an odd one cropping up on my barge setup that I reckon some of you 3-phase folks might recognise. Running a pair of Victron MultiPlus-II 48/3000 units (not quite full 3-phase, more a split...
@CallumHobbs depends massively on the freezer tbh. A decent efficient one (Dometic, Engel, etc.) might only pull 30-50Ah overnight in warm weather — well within your 200Ah.
