Had something almost identical happen with my setup last year — Victron Multi-RS 48/6000 refusing to budge out of storage mode even though the JK BMS was communicating perfectly with the Cerbo GX.

CamperSam replied: @SmartSolar_Queen Right, ignoring the forum gobbling up half these posts like a hungry seagull... Classic MultiPlus charger dropout.

Been having a nightmare with this exact thing on my narrowboat setup and wondering if anyone else is seeing it. Running a Cerbo GX alongside a pair of Victron SmartSolar MPPTs and a MultiPlus-II...
Really useful thread this. Following @VivaroWanderer and @Ben1960's points on parasitic loads — one thing I've been trying to get my head around for my van build is whether it's worth fitting a...

Running into something similar with my shepherd's hut build and wondering if anyone else has hit this wall. Setup is: Multiplus-II 24/3000 (latest firmware) Cerbo GX (v3.73) SmartSolar 150/85 2x...

@Frank1969 curious what your setup was when that happened — AGM or flooded? For anyone considering this for a van conversion, worth flagging that the MS-PAE 4448 isn't exactly compact.
Good point from @CurrentAffairs on the app config. One thing nobody's touched on — check your input voltage under load.

Had similar grief with my Quattro in the motorhome last year. Worth checking your generator's Hz output under load — mine was drifting badly once the EV charger kicked in and drew heavy current.
@Boycie25 good catch on the VE.Bus conflict — that one bites people hard. One thing nobody's touched on yet: assistant switch / remote on-off terminal.

@OldSparky VRM as proof of purchase... imagine trying that with HMRC 😂 Seriously though — has anyone actually phoned Victron UK direct rather than going through a dealer?
Been running a similar Victron setup for about 18 months now and the solar priority question comes up constantly in my system tweaking. My kit is a MultiPlus-II 48/3000, Cerbo GX, Fogstar Drift...
Living on a narrowboat means my panels get a special seasonal coating of tree dandruff, canal algae and whatever the ducks decide to contribute — pollen is honestly the least of my worries.

Did something very similar about 18 months ago — converted a 1970s hut that had been rotting in a field corner for years.

Seen this exact behaviour on my own setup last winter. The Victron Smart Lithium cells have a low-temp cutoff that kicks in well before you'd expect — something like 5°C for charging, if I recall...

@LiFePO4Fan done this on my own static — one thing nobody's mentioned yet: double-check your grid code settings in ESS.
Really interested in this thread — I've got a Pi 4 sitting in a drawer doing absolutely nothing and my narrowboat setup is crying out for proper monitoring.
@YorkshireExplorer makes a good point about repeated clicking being the tell-tale sign something's off. I had a similar saga on my narrowboat last winter — turned out my grid connection was...
ShaunWard replied: @GrumpyBuilder I'd push back a bit there — it's not quite that simple. The SmartShunt is brilliant at coulomb counting but it drifts if you haven't given it a proper full charge...

@Gibbo @LazySparky @SilverMender — all useful stuff, cheers for laying the groundwork. Slightly different angle: has anyone actually done a twin Multiplus II setup in a UK coach conversion...
