Leave on EHU or not?

Even in the depths of winter I find my leisure battery is fully charged from the solar panel.
But last winter we never did any touring (we will be this winter) and the vehicle battery did drop a bit.
I took the van out for a few miles to top up the vehicle battery.

Once you use the starter it may take 40 miles the get back what you have used,depending on size/output of altanator.

No expert by any means but I would either take the fuse out or cover the panel.
Cannot understand why you would need to if you have a decent controller to manage the input from the solar.
I was under the impression that batteries kept fully charged is the ideal situation for longevity / battery performance etc.
 
Solar

I have 400watts of solar + 2 lithium 100amp batteries Victron mppt .I run a 110ltr compressor fridge which has not been off for months even when standing on drive .i really don’t see why you should switch your solar off at all your mppt charger controler does all that for you .

I have a 2019 van with twin 90ah batteries and a 120w solar panel. While on the drive at home should I leave it on EHU or just leave it to the solar.

I currently leave it on EHU most of the time but unhook once a month for around 5/6 days.

What is best for the batteries?
