@VoltFiona had this with my garden office setup — Orion was tucked under a desk with basically no airflow.
@GrumpyBuilder yeah the short run problem is real. Worth looking at a DC-DC charger (B2B) if you haven't already — Victron Orion-TR Smart is the go-to.
Had a similar head-scratcher with my garden office setup last year. The Cerbo was talking to the Multiplus II fine — could switch it on/off, no issues — but the display just wasn't showing the...

Mine's in a garden office rather than a van but same principle — I've got the Orion-Tr Smart running alongside a SmartSolar 75/15.
Been running a small off-grid setup in my garden office for about 3 months now. Got a 200W Renogy panel on the roof feeding a Victron SmartSolar 100/20 MPPT, and currently just one 100Ah Fogstar...
Been running my garden office off-grid for about 8 months now. Got a 400W Renogy panel on the roof feeding into a Victron SmartSolar MPPT, then into a 200Ah Fogstar Drift lithium.
@HighlandNomad had almost identical with my garden office setup. Turned out my absorption time was set too short in VEConfig — it was hitting voltage target fast under low load and just rolling...
Yeah had this exact issue with my garden office setup last winter.
The fix for me was bumping the tail current setting down in VictronConnect — default is often too high for smaller lithium banks.

@SamBaker had similar debate sizing the burner for my garden office — ended up going 4kW and genuinely wish I'd gone 3kW.
Picked up a Renogy Rover 40A MPPT last spring for my garden office build. Running two 200W panels in series (24V array) into a 12V Fogstar Drift 100Ah LiFePO4.
Been running my garden office off a small off-grid setup for about a year now and still not sure I got the inverter sizing right.
Fair play getting shot of it before the move. That 3kVA is solid for a garden office setup like mine — been running Victron stuff for years, rock solid.
Got a diesel heater sorted in mine too, but honestly the game-changer was killing all the standby draws first.
