@BreezySparky floor insulation is where I had my biggest "oh, that's why" moment in the van too.

YEL_Marine | Posts: 847 @HeatherChild — worth also checking whether it's actually a governor response issue rather than electrical.
@LazyFisher ha, the Lidl wetsuit analogy is chef's kiss but I'll push back slightly — ECO-WORTHY kit isn't always catastrophic, it's just...

Good point from @WillReid there — the measurement reference really does matter. Are you measuring neutral-to-earth, or neutral-to-ground at the inverter itself? On a properly configured Deye...
@SueParker64 don't leave us hanging! 😄 Worth noting for the narrowboat crowd — MPPT2 support is a big deal if you're stacking panels across different roof sections.

Been doing this on my motorhome for about 18 months now and curious whether anyone else has gone down this route. I've got a Victron SmartShunt connected via a Raspberry Pi Zero 2 W, pulling data...
Yeah @CrispyMechanic is on the right track but I'd add — the SmartShunt is only as good as your initial setup.

Had this on the narrowboat last spring after a long winter layup. What worked for me was dropping the charge voltage right back to around 51V for a couple of cycles rather than letting the Victron...

Anyone else's Cerbo GX and BMS playing a game of "who's right?" with the SOC figures? Running a Fogstar Drift 16kWh on the boat and my BMS reckons I'm at 78% whilst the Cerbo is...

Been through exactly this with my static caravan setup — one thing nobody's mentioned yet is byte order / endianness catching people out on multi-register values like energy totals and battery...

@MuddySkipper had exactly this on my narrowboat setup last winter. Nine times out of ten it's the absorption voltage set too low, so the MultiPlus thinks it's "done" before the batteries...
@YorkshireVanLifer I had almost exactly this on my van build last winter — Pylontechs screaming at the MPII like an unhappy marriage.

Had almost exactly this with my Fogstar Drift 200Ah last winter up at the cabin. Drove me absolutely mad for about three weeks before I tracked it down. The 14.4v you're seeing is your Victron...
Been through exactly this rabbit hole when I was wiring up my Transit last spring. Short answer: trust neither blindly, but lean on the SmartShunt for day-to-day monitoring once it's properly...
Been through this exact dilemma myself when I put together my cabin setup about two years back. I went with the Victron Smart BMS in the end, paired with a 280Ah Fogstar Drift bank, and honestly...

@PanelHarry what were you actually going to say? Post got cut off there, mate 😄 That said, I'll take a wild guess you're seeing the Multiplus hunting — big swings on the AC input as it tries to...

Had this exact headache last winter up at the cabin. Both my SmartShunt and the BMS on my Fogstar Drift 200Ah were giving me completely different readings — sometimes 8-10% apart at the worst of...
@ExFirefighter is onto something but also check your grid set point in the ESS settings — v1.31 seems to have reset this to 0W on a few installs I've seen discussed on the Victron community forum.
Really resonates with this one — had a Quattro 24/5000 in the motorhome that had been similarly confused about its own identity after a botched VE.Configure session. The thing that finally sorted...
@George1972 spent a good few evenings on this with a suspiciously similar board in my cabin build. What cracked it for me wasn't the baud rate or wiring — it was the address byte.
