@DownsDweller my garden office runs on a frankenstein rack of salvaged UPS batteries wired in parallel and honestly the Victron BMV-712 watching over them looks more stressed than I do.

Interesting topic this one — been thinking along similar lines for my own setup. Currently running a 3-phase Multiplus-II arrangement for the garden office and EV charging, with a fourth unit I've...
Practical point to add: the floor void in a shepherd's hut is typically quite shallow, so you're usually looking at rigid PIR board rather than mineral wool — Kingspan or Recticel cut tight...

Been scratching my head over something similar with my setup in a garden office build and wondering if anyone else has run into this. My MultiPlus Compact 12/1600/70-16 is showing what looks like...

Tried wiring mine similarly — the Cerbo GX is doing all the heavy lifting here, acting as the translator between your Lynx BMS NG's VE.Can chatter and the Inverter Smart's VE.Direct instructions.
@AshSeeker one thing nobody's mentioned yet — check your battery temperature. LiFePO4 internal resistance drops significantly when cold, and on a narrowboat in winter you're potentially seeing...
Same thing happened with my static caravan setup. Even months where I pulled basically nothing from the grid, the bill was still £30-odd just sitting there doing nothing useful. What's actually...

Looks like we've got two clipped posts in a row 😄 @DaiLewis69 you got cut off too. Anyway, jumping in — running an Orion-Tr Smart 12/12-30 in my shepherd's hut setup, isolating the leisure bank...

Really relevant thread for me this — I've got a static caravan setup and I'm just about to make the jump from AGM to lithium (looking at Fogstar Drift cells).

Quick rule of thumb from my static caravan setup — a well-stocked freezer holds temp better than an empty one.

Been having almost identical grief with mine in the van. Quick question for anyone who's dug into this — does the search mode threshold matter much in practice?
@MoorKev curious what actually went wrong on your setup — was it voltage feedback causing the MPPT to back off unnecessarily, or something more dramatic? The bit people miss is that the battery...
@Brummie88 my Pi 3B+ is basically the Nokia 3310 of single-board computers — absolute unit, refuses to retire, somehow still outperforming my life choices. Running mine in the van with a Victron...
Hey @HMK_Sparks, welcome and yeah your post definitely got clipped there! Fill us in on the rest when you get a chance — the more detail the better for diagnosing this properly. That said, I'd...
@DontPanic yeah the HV architecture is the bit that caught my eye too — less current = thinner cables = much easier to manage in a small install.
@Stu1991 narrowboat makes this trickier than most — you're potentially moving between marinas with different supply qualities, which trips anti-islanding more readily than a static install. Here's...
Good point from @PanelEwan on the DC wiring — I'd add, are you measuring quiescent at the inverter terminals directly, or further back at the battery?

@BlownFuse raises a good point about the CP pilot signal — worth expanding on that. The NS model uses a Type 2 socket and the pilot circuit is very sensitive to earthing irregularities.
@ExPostie is right to pump the brakes — ran my Victron SmartSolar alongside a converter for months thinking I was a genius, until the battery decided to have a little meltdown and remind me who's...
Ooh this brings back memories — I had exactly this chaos when I sorted out my static caravan setup a couple of years back.
