Ordered goodies have arrived as suggested.
1 X MPPT Victron controller 75/15
1 X 5m pannel to battery extension lead
2 X battery plugs w/t 10a fuse Anderson connectos.
So, battery connection will have 2 fuses one on the eyelet connection with 10a and the main connection lead leaving the controller which has 20a fuse. Is this ok?

Do you mean this cable? This is extension to the battery from the controler with Anderson connector (option of crocks or eyelets).
I have been following this with great interest as I want to do exactly the same but the way it looks to me is that with the long cable going from the battery to the controller then the controller will end up being outside?
wouldnt it be better for a short run batt to controller and then long run controller to panel or am I misunderstandin?
Well, I would place the MPPT controller as close to the battery as possible. Then the long cables would be from MPPT to panel. Which is the same as you.
well in my case now i have option of both, long battery lead from panel with attached controller, or long controller cable with short battery. Is there advantage having MPPT controller as close to the battery as possible? I have attached my controller to the back of the panel via heavy duty Velcro, i think it will be tidy keeping it like this.
The normal convention is to have a longer PV lead....
And a short-as-possible battery power lead.
You can obviously do both,.
The only downside to the longer battery lead is a slight volt drop and loss in charging power & effiency.
You can always make leads as long as you wish to suit your setup.

Agree. I wouldn’t want my Victron MPPT out in the weather though. I’m sure it’s not even water resistant. Much better to have that inside the van near the battery and the long lead to the panel imho.
Its always good to have a range of extension cables and options for deploying mobile solar.
It will depend on the location at the time.
As an example....
I had the van parked in the shade and deployed mobile solar while camping.
I had a long PV extension cable connecting the panels in the sun to the controller that was in the awning. Which was conected to to a short battery lead that was charging the battery box in the awning.
Once the battery box was charged up..... i plugged in the long anderson extension lead to connect the setup to the van battery to charge that.
Saved moving the whole setup closer to the van.

I dont think EdH will be swapping from 1 battery to another. Also in none of the setups you have the Victron MPPT outside exposed to the weather.

Now flat on the ground directly facing the sun but only showing 6w? I thought it would be more than this? @Dellmassive
