What is the size of the wiring as you are quadrupling the current

If it is 4 mm then you will be fine but less than that I would run new cable

You will prob need to upgrade the charge controller

this is the one we used for my dads camper - teach me to be a cheapskate

the 2 leisure batteries should really be the same make, age and size, wire them in parallel and you just use the one output

you also wire the 2 solar panels in parallel

That's great Rich, thanks so much for the info. I'm going to have a go at this in a weeks time.
