Solar question

[neo_daz]

Good morning

We have an existing solar on the roof (80w) and a portable 200w panel
I wanted to put these separate into the victron mppt100/30
Can I put the negatives into the controller and use a 3way switch for the positives to switch them over when needed as the current 80w panel will pull the other down ?

I have my portable panel direct to the battery as it has it's own solar controller ...
I installed an Anderson connector on the skirt of the motorhome, which also now gives me an external 12v connection, which I use for a tyre inflator or the Starlink
