Really relevant thread for me — also running a shepherd's hut with EVE cells and a JK BMS, so watching this closely. @SomersetNomad what's the "known issue" you were about to mention?

@CraigCross one thing that trips people up with the Multi RS — it needs a specific VE.Can profile set correctly on the Cerbo.
Really curious about the load-balancing side of communal setups — in a tiny house context (which is what I'm planning to move to eventually) you'd think each unit having its own dedicated system...

@VanLee Error 10 is your Multiplus screaming "oi, sort your DC voltage out" — classic symptom of a dodgy connection somewhere rather than the voltage itself actually being wrong, so...
@MidlandsSolar makes a fair point. Worth adding — if you're using Fogstar or similar cells and building your own pack, double-check your BMS cutoff sits comfortably below that 58.4V ceiling rather...
Been wrestling with a similar headache on my cabin setup — though mine's single-phase, the underlying physics is the same and it might help narrow down your culprit. DOL (direct-on-line) motor...

@DefenderDream one thing worth checking that nobody's mentioned yet — have you looked at your cell internal resistance readings in the JK app during the cold spells?
Been thinking about this a lot lately after pricing up a few different setups for my shepherd's hut project and helping a neighbour look at options for a small residential build. There's a real...
Been running a Victron MultiPlus-II paired with a Cerbo GX in my motorhome conversion for about 14 months now, and something's been nagging at me that I wanted to throw out to the forum. I'm using...
Been there mate, absolute nightmare timing. When my old Victron Phoenix gave up the ghost in January a couple of years back, I grabbed a Giandel 2000W pure sine from Amazon as a stop-gap.
@VDH_Boats worth checking your VictronConnect history logs — the app timestamps every fault event and records the internal temp at dropout.

LizHunt | 412 posts | ⚡ Off-grid since 2021 @ForestDaz worth checking whether Venus OS 3.81 reset your VE.Can port settings — I had something similar (different BMS, admittedly) where an update...

@BevJackson64 I feel that northern winter pain — spent two seasons in my motorhome up near the Lakes and there were whole weeks where the panels were basically decorative. What finally sorted it...
Ran into something eerily similar on my motorhome last winter — Cerbo GX on v3.79, MultiPlus-II 3000, Fogstar Drift 200Ah on CAN-bus.
@RustySpanner is spot on about the PM motors. Worth adding from my own experience — the rewound stator is where the real magic happens with these salvage builds.

@MikeCross the fix nobody mentions: drop your SmartShunt charged voltage threshold to about 0.2V below whatever your BMS terminates at.
Been getting a VE Bus Error 10 popping up on my Multiplus-II 3000 over the last week or so and it's doing my head in.
@Squib yeah I ran a single Multiplus II for a while feeding two separate DB boards — works fine until one location pulls a big load and the other browns out.

Been seeing something odd with my Cerbo GX since updating to 3.81 and wondered if anyone else has clocked this. Running a MultiPlus-II 48/5000 in the shepherd's hut — got a Victron MPPT doing most...
