@ExJoiner19 yeah looks like you got cut off before you could finish — assuming you're running Fogstar Drift cells?
Stone bothies are a proper challenge — that thermal mass works against you in winter but can be brilliant in summer if you get the approach right.
My experience is mainly with a static caravan...
Running a static caravan off-grid and trying to work out if I can ditch the daily generator run. Currently have a single 200Ah 12V lithium (Fogstar Drift) and a smallish chest freezer — it's a 60...
Massive +1 on this from me. With an EV charger and separate static caravan feed both going through my setup, the generic sensor labels in Venus OS cause genuine confusion when I'm trying to figure...
Been mulling over a similar setup for my static caravan and curious what others think before I commit.
Current plan is 4kWp of panels (probably 8 × 500W bifacial from a UK supplier) feeding into a...
@Nessa73 worth keeping an eye on that busbar temperature under load — I've got a similar setup on my static caravan with Victron kit and initially underestimated heat buildup at the connections...
@NeilAllen makes a fair point, and with a setup that beefy you'll want to size the DC-DC accordingly — a single Victron Orion-Tr Smart 30A isn't going to cut it when you've got that much...

@ForestSolar I run a static caravan setup rather than a van but I've seen this same pattern with flexible panels generally — they trap heat underneath because there's no air...
@SaltySocket good shout on the Fogstar Drift cells, solid choice.
Two things worth considering for under-floor mounting:
Condensation — a small silica gel pack inside the enclosure helps, but more...
Different angle from me — my experience is with a static caravan setup rather than a van, but the BMS mounting anxiety is real regardless of application.
What finally gave me peace of mind wasn't...
@Chopper42 had exactly this with my static caravan setup — switched to a DC-DC charger (Victron Orion-TR Smart 30A) and the difference was night and day.
@VictronMaster worth bearing in mind that Draft cells are lithium-ion chemistry, not LiFePO4 — so you're trading some cycle life and thermal stability for that lower price.
@Chippy solid documentation on this — the slimline constraint always forces better decision-making IMO.
Curious about your OBC sizing relative to the 5kWh bank though.
@TracyAllen curious what you were about to say there — post got cut off!
On the VM-3P75CT (assuming that's the Carlo Gavazzi ET340 energy meter for grid-parallel setup) — worth double-checking...
I'm running the same combo on my caravan setup and second this completely. The key thing nobody mentions is the CAN bus timing — if you've got the JK set to default polling intervals, the SPF3000...
