Can I charge 2 deep cycle batteries with my car alternator and a 200w solar pannel kit at the same time?

I have a conversion van with 2 deep cycle batteries in paralle hooked to my .
I want to add a 200w solar power set up with a 30 amp solar charge controller to charge my batteries in conjunction with the alternator.
I only drive 20 minutes a day and I live in my van.
Can I hook up the solar set up with the alternator set up?
I also have a 2,500 watt power inverter hooked to my 2 deep cycle batteries.
If you have any information on a set up I can do please help, thank you.

Wire in parallel and make sure you have protection diodes on the panels.
