Cool, the manual is one thing but good to have confirmed.
So, I had a look after 5 mins driving on school drop off and it was showing the first two screen shots, although it was notable that the input voltage varying slightly every couple of seconds. The second couple of screen grabs were taken this evening after about 20 mins driving with heater fully warmed up...something has clearly kicked in at that point...does this all look fairly normal?
I have noticed that my battery seems to discharge over the course of a week even though I've only using it to go to work and done no camping past few weeks. It goes from 5 to 2 bars on the monitor in van in the course of a week. Admittedly its not getting much charge on my short journeys but is it normal to lose that much charge I a week?
Thanks again, Mark
What monitor are you talking about that goes from 5 to 2 bars?
Ok, so it's definitely charging sometimes whilst being driven, so the DC-DC is basically working. I'd have a look at the solar controller in decent sunshine too just to verify that's also working. The reason why it's sometimes running and sometimes not when driving is that you don't have an explicit ignition or engine run signal (unless it's hiding in the photos) to tell it to turn on so it has to rely on assessing the voltage. The voltage flies around all over the place depending on the electrical load on the van, regenerative braking spikes, etc so it can be a bit erratic. If you want to play with it, you can change the voltage detection parameters to try and make it more sensitive to come on more.
As to your other question, it really depends what five bars to two bars actually means in terms of state of charge. It's probably relying on simply voltage thresholds so is probably not very closely calibrated to your battery. The important thing is that you don't have any meaningful drain when it's just sitting there - e.g. leaving a fridge on or something, that would definitely cause it to lose charge quickly.
Afternoon all!
If its the Sargent panel - same as i have in mine like this:-
Then, the battery status is given based on voltage alone like this:-
Is this the same panel you have in your van?
With regards to the engine shutdown detection, you just need to change the shutdown detection settings in the B2B charger to overcome that.
I will share my settings that work well in my T6.1 if needed

The one that came with set up ( pictured)
Like you say, I'm unsure if theres too much to gauge by the bars. It was on 2 this morning and upto 4 when I got home after 20 minute drive.
That would be helpful..many thanks
In that case, if its an AGM battery and its regularly below 11V then the battery may be not great condition.The one that came with set up ( pictured)

Oops forgor to add pic.. this is mineThe one that came with set up ( pictured)

It would appear it’s this unit VEGAS Control Panel 12v Battery/Water c/w Surround Caravan Motorhome BC21008 - Caraquip
