Does anyone have a recommendation for a portable solar panel suitcase.

I have been looking at a "Renogy 200 Watt Off Grid Portable Foldable Solar Panel Suitcase Built-in Kickstand with Waterproof 20A Charger Controller, 200W-Waterproof" but I'm way over my head and not sure on what to get. I was hoping that maybe some of you might have insight/experience on what to get.

I have a Rig with 2 lithium batteries and would like something other than my Inverter Generator that I keep in the truck, to keep them charged during the day.

Any recommendations?

Thanks in advance.
