I have recently purchased a caravan with a 240litre compressor fridge /freezer. The van has 2 x 120amp batteries charged by 300 watts of solar panels on the roof of the van...seems to work well.

But i would like to add more solar , so my question is ...i have 160 watts of solar panels on the vehicles roof rack .
So if i simply connect the 160 watts by anderson plug to the van will this assist the van ?

The panels on the vehicle have a mppt controller attached to the panels , do i need to bypass the mppt controller and feed the higher voltage into the van or just plug the panels output after the controller into the van.?

The van has a 40 amp controller.

Any suggestions please.
