Had exactly this with my Orion 30A about 18 months ago. Turned out to be a thermal shutdown issue — the unit was mounted inside a cupboard with basically zero airflow.
Bit of an odd one with my garden office setup and wondering if anyone's seen similar.

Been setting up Node-RED on my Cerbo GX to handle some custom automation for the garden office — basically want to control Relay 1 based on a combination of SOC thresholds and load spikes rather...
@DougPearce yeah the post got chopped, need the full details before this goes anywhere useful. What's the actual issue you've hit — is it a comms problem between the BMS and the inverter/charger,...
Got a similar setup in my garden office — Multiplus-II 48V with Fogstar Drift pack.
The low voltage grid enable issue usually comes down to the AC input current limit settings in VEConfigure...
Finally pulling the trigger on getting my garden office off-grid (or at least reducing the bills). Don't need to run anything massive — just a laptop, monitor, a few LED lights, and maybe a small...
Running something similar on my garden office — generic 20A blue job, single 100W panel into a 100Ah AGM.
Key settings I landed on:
Boost voltage: 14.4V
Float: 13.8V
Boost return: 13.2V
Low...
Been through similar with my garden office setup. One thing worth flagging — PWM controllers can't really harvest the extra voltage cold panels produce the way an MPPT would.

Garden office setup here so smaller scale than yours @SussexDweller, but I did experiment with trickle charging my van from the array during summer.

Seconding what @Geordie said about VictronConnect — the history graphs are gold for diagnosing this.
One thing nobody's mentioned: check your AC output wiring too, not just DC side.
Running 48V in my garden office setup and honestly, cable losses were the game-changer. In a Sprinter though, space is tight—what's your actual run length from battery to main loads?
Spot on about the resale value — Victron stuff's solid. Only thing worth flagging: check your battery bank specs before anyone bites.
