@ExPostie VE.Bus Error 19 is a phase sync issue — the Quattros aren't seeing each other properly on the VE.Bus cable chain.
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.
Had exactly this with my shepherd's hut setup last summer. BMV was reading 100% and showing full charge, but when I dug into the VictronConnect app the cells were wandering — worst case I had...
Good timing on this thread — ran into something adjacent when I was commissioning the garden office setup last spring.
Worth checking your AC-coupled PV assistant version in VenusOS.
@PN_Camper what battery are you running alongside it? I've got a Fogstar Drift 200Ah paired with a Victron MultiPlus on the shepherd's hut and communication was straightforward, but I've heard the...
Had this exact issue on my shepherd's hut setup last winter. The Daly low-temp cutoff is one thing, but worth also checking whether your charger is pushing full current right from the off — even...
@CamperBaz I'd ditch the split-charge relay alongside a B2B — you're essentially fighting yourself. The B2B already handles the isolation and charge profile properly for lithium, so a relay just...
Currently running a 200W Renogy panel through a Victron SmartSolar MPPT 100/20 on my Transit-based motorhome.

@BatteryBarry running a similar setup in my shepherd's hut-turned-office — 16x12ft.
One thing worth adding — compressor fridges can pull a decent spike on startup, so worth checking your BMS can handle it without tripping.
Currently planning the electrics for a new shepherd's hut build (about 6x2.5m) and I'm going back and forth on system voltage.
@VoltPaddy good practical question regardless of the missing post.
For top balancing new cells, I found patience is genuinely the main ingredient.
Worth adding from my shepherd's hut setup — the DVCC settings are where people trip up most. Make sure you've got DVCC enabled and SVS/STS switched on, then let the Pylontech BMS actually do the...
Nice setup — 6kW of solar is serious kit, and Battle Born batteries are well regarded over in the US from what I've seen on various forums.
Quite different to what most of us are running here in...
The jump from lead-acid to LiFePO4 is genuinely transformative. @OffGridHamish's right — it's a completely different experience.
What clinches it for winter: you're not just doubling capacity,...
