Connecting two solar panels through 1 regulator

Good afternoon from Sydney,

Long time lurker first time poster.

I have been searching through a lot of old threads regarding hooking up to solar panels but seem to be confusing myself.

My truck has 2 Aux batteries fitted (105A & 120A) professionally installed prior to me purchasing the vehicle. I am running a waeco 90l fridge freezer and was running a power tech 120w panel
120amp
I had issues with the regulator and by passed it and ran it through a steca PR3030 controller mounted in the rear of cab close to batteries
steca 3030

I like this controller as it allows me to keep an eye on everything whilst camping.

I recently purchased a KORR lighting 150w solar blanket

I am also using the steca regulator for this and works fine but my question is, if I wanted to could I run both in series through the steca?

Being a 30amp controller it will handle the increase in amps but have been reading things about reverse diodes in the system which is confusing me.

I have read that connecting panels of different size or type is not recommended.

is it just a matter of connecting both panel leads together at the controller and let the controller do its thing?

Many thanks in advance,

Cheers
Knuckle
